Car magazine writers can be very tough on certain vehicles and manufacturers.
A great example is with ergonomics. Traditionally companies like Honda put in more time and research to make sure that their cars are universally accepted than say, Nissan. More people will say the shift linkage on an Accord is “smoother” than a Maxima based on factors that might not even stack up in the performance world. I won’t go so far as to claim conspiracy theory based on advertising expenses…but obviously cars like BMW and Honda have set the standards for the editors. Some of which are actual car enthusiasts and the rest are excited by Mini vans and back-up sensors. I give Honda and BMW credit for their accomplishments (as they make fantastic products) but want to scold editors for their one-sided perspectives on what is the “holy grail of shifters”.
In the aftermarket world you can’t fix many ergonomic problems. You can replace the seats with something custom providing more lateral support but the way the door-knob operates is usually set in stone. You can replace shifter bushings and the linkage but a sloppy transaxle is going to be miles behind a smooth one to start with (ex: Cavalier vs Civic).  What can be fixed is many of the severe “problems” that the magazines find with a car.

For example, the new 2008 STi.  Many reviews comment on its severe tendency to understeer.  This year it has 245/40/18’s instead of 225/45/17’s so right away you have more tread on the front which actually can lead to more understeer if everything is left the same. The car also has a new multi-link rear suspension, which by nature provide negative camber angles on transitions providing more grip in the rear (providing more scrub in the front). The chassis is also stiffer than ever before giving less lateral flex and more noticeable “soft springs”. The fact is the new car pulls slalom numbers beating the car it replaces in stock trim. With some alignment changes (for less than $100) you can give it more oversteer than a Mustang. If you want to actually spend money Cobb makes a swaybar kit which allows for 235-500%+ rear bar stiffness which would allow you to trail-brake it wonderfully. This is just one example that the media picks on.

In summary, there are things that you can fix and others that you cannot. To condemn a manufacturer based on understeer is a bit extreme in my opinion while having uncomfortable seats is a completely different issue. I can have an alignment done, play around with tire pressures, and make an engine louder…I can’t really convert a front wheel drive car to a mid-engine 2 seater. Since reviews are almost completely subjective we have to weigh the results, do our own test-drives, and crunch the numbers.
Don’t believe everything you see on TV (or definitely read on a forum).

Making a modern car handle is getting easier every year.

Even the “economy” vehicles are equipped with solid chassis, adequate suspension travel, and a general lack of mass.  Even five inches of near-race rubber will generate forces requiring some driver training.

The first thing that people to modify is the stock springs.  Obviously if the car rolls side to side it’s because the springs are too soft and the engineers were planning comfort over skidpad and slalom results.  The masses will typically price out an expensive set of coilovers assuming they must be much better than springs and allow them to drop the car within an inch of rubbing the fenders…it’s what they do on Gran Tourismo so why not?

There is no problem with spending thousands on a set of coilovers (we sell them on the site and won’t fight you).  However, the biggest problem with the modern vehicle is not spring rate…its rubber and alignment.  The engineers will generally spring a modern vehicle efficiently so that bumps don’t unsettle the chassis and that the progressive nature of the spring supports the vehicles weight well.  Most “tuner” springs are also designed for the public so a spring rate (progressive or linear) increase is 10%-30%.  The 10% are the “sport” springs which are typically progressively wound so ride nice and only drop 1-1.5 inches which is respectable.  The “race” springs are stiffer, usually linear wound (as in, one inch of travel equals half as much spring torque as 2 inches…the coils are spaced a similar distance apart).  They also drop the vehicle 1.8-2.5 inches which can really knock your stock alignment for a loop and do things that the engineers never intended.  You see, whether you have a strut or multi-link system, your shocks and suspension arms are assuming a standard ride height so when you cut the suspension travel and ride position in half they don’t act in the same fluid responsive way (try running a marathon bow-legged).  You also run into the problem that a simple dip in the road which your stock suspension would soak up gently your new “race suspension” which is designed for flat-track surfaces and aggressive alignment settings tends to jump and buck.  This is NOT the fastest way around a corner nor the safest.

I could talk quite a while on the difference between a proper coilover kit, a conventional strut/spring upgrade, and just doing springs but that’s not the point of this blog.  The point is that people gravitate towards the most expensive/shiney upgrade rather than the one that makes the most sense.

You will not get much “street-cred” at the local donut shop (or wherever you hang out) with a set of GOOD tires (the kind that you cant drive well in the rain and that wear out quick) and an aggressive alignment but you will be faster on the track.  You will need tires anyways because running all-season economy tires on any track vehicle is dangerous.  Upgrade these and run a little negative camber in the front and the rear for increased cornering stability.  Your inner tread will wear a bit faster but the performance upgrade is worth its weight in gold.  With a FWD vehicle 1 degree in the front and rear is reasonable and will produce a little worse freeway tracking (and treadwear) but nothing like the 3″ dropped Honda Civic guys who show steel cords like marks of glory.  All wheel drive vehicles should go with similar figures for streetable performance.  High horsepower RWD folks or those with very sticky rubber (R-Compounds or cheater slicks) should vary this 1.0-3.0 degrees depending on how much street driving they do and their goals.  You can stagger alignment front and rear a bit to get the right cornering balance or keep better traction with less rear negative camber.

Toe setting changes should be addressed with the utmost concern.  They can make a HUGE difference in the mannerisms of a vehicle but can also turn it into a Frankenstein monster.  One degree of too much rear outer toe can turn your civil mustang into a non-stop drifting machine (in a bad way).  Likewise, caster settings allow for: ease of steering effort, front-line stability, and more aggressive turn-in.  Of these settings camber and toe are easier to modify without expensive devices.

That’s basically it: Tires and Alignment.  With the right combo you can turn impressive numbers and never bottom out on your favorite speed-bump again.  Granted, a set of $2500 coilovers and $500 swaybars could make the car much more impressive…but it’s a bottleneck of performance and you just cant beat those first two mods for the money.  Swaybars are almost tied for second but with how pathetic the stock alignment settings (well, just tuned for comfort) are and how cheap it is to fix it should be done first.

Here are some extremely rough ideas of pricing to better explain the above belief:

1.)  Tires:  Depending on wheel size and width these range from $80-200 each.  I like the Falken Azenis line for a dual-purpose track tires but Hanzook, Toyo, Kumho, Yokohama, and Nitto have some impressive versions too.  Stay away from the big-buck Bridgestones, Goodyears, Michelins, etc because a Falken RT-615 will blow them away for the money.  (installation should be $60-100)

2.)  Alignment:  Minor toe settings can be done for the price of a standard alignment for most vehicles.  You don’t need much to completely change the demeanor of a vehicle…so look around for recommendations.  A standard alignment is $89-180 depending on the make/model so add $50 assuming the tech will take a bit more time.  A cheap camber kit for the front is about $20-30 and $80 for installation but if you do the alignment with it they will probably package price the job.  If your going extensive with caster/camber plates, rear camber bolts, etc you can spend $400-600 for an alignment but your probably headed to the Nationals so who’s adding up receipts?

3.)  Swaybars:  These run about $200 each and usually come with urethane bushings.  They can squeak a bit so keep them greased.  The rear bar is normally an easy install (figure $150 ish) while the Front is a pain because the engine is right on-top of it so the labor can be in excess of 5 hours (or approx $500).  These make a HUGE difference and should be done right after the above two steps.

4.)  Coilovers, springs, struts, etc:  A simple spring drop will probably cost you $700 ($300 springs/ $400 labor) but a Civic is far different than a BMW M5 so keep an open mind.  Coilovers range from Ebay specials that probably wont outperform your stock units (or will with extremely noisy/fragile results) to $4500 race units.  A good middle range for any quality spring/strut or coilover setup that I would be proud to have would range $1200-1800 and install will run about $500 plus an alignment.  If your not a real suspension tuner then go with a pre-set system.  If you running race tires and test-and-tune laps then adjustability rules the game (same goes with adj. sway bars).

If you can’t decide what to do, get the sportiest tires possible and test them out.  It’s better to replace them once or twice a year than to run expensive suspension with crap tires.

Have fun out there and enjoy the dry pavement.

This product should receive more praise and attention that it has thus far. To be quite frank, all of the information that I have received till now left me with some questions also. Well, that was until I talked to Jeff Perrin on the phone.

Factory turbocharged vehicles have a solenoid system controlling wastegate pressure (which in-turn provides boost control). This product essentially replaces that factory solenoid which is often times a “bleed type” unit and allows for easy boost tuning. The upgraded Perrin unit is an “interupt” style that allows pressure to be stopped and continue with much more accuracy. Another way to look at it is a slipping clutch opposed to a new upgraded one…they both will get your car going but you can accelerate MUCH faster with the new one. You can reduce turbo lag by making the system more efficient than the factory setup.

This Perrin EBCS is a great answer to any factory turbocharged vehicles that use a solenoid system as described above in conjunction to their wastegate. If your factory computer is tunable for fuel/ignition this will save you a ton of money over an electronic boost control (like the Apexi AFC-R or GReddy Profec B).

These fancy electronic boost controllers arrive in-box with a similar valve to the Perrin unit coupled with the electronic brain for controlling boost….if your factory computer can do it why bother with another?

Another solution to budget boost control is with a manual boost controller. You can limited wastegate bypassing and increase the boost but depending on temperature, humidity, elevation, etc this boost can change daily. With larger turbo cars wastegate flow in each gear can give you different boost levels. It’s a rudimentary system but works in a crude way.

In summary I think that Perrin has hit the nail on the head with this unit. For 90 bucks its a steal for the sophisticated control it offers and can simply improve factory conditions at the same exact boost levels. If you have a factory turbocharged vehicle, check this out with some type of air/fuel tuning software. You will get 9/10ths the performance of a standalone electronic boost controller for most of applications for much less hassle.

If your lucky enough to have a tuner offering reflash software like Cobb Tuning then your a very lucky person and don’t really have to worry about grouping tuning tools together…just get the best one out there and enjoy the ride.

There are many marketing gimmicks in the automotive world.

Most of these just entertain someone for a few weeks, give the sales person a nice pitch of sales trickery, and ultimately break after the warranty is out leaving huge bills for something lackluster to begin with. Four-wheel steering, electronic suspension from the 80’s, and the “Power” button on the auto transmission of some Toyota SUV’s that just doesn’t deliver comes to mind (don’t get me started on electronic parallel parking cars or headlights that dance on start-up).

I definitely have my cynical side which makes my perspective on Subaru’s “SI Drive” a balanced one. This system adjusts the throttle response depending on setting from mild to wild. This system first became available in the Legacy Spec B in 2005 to current and is now available in the STi for 2008+.

In “I” mode its basically the economy system that gives slow rising/falling revs, laggier boost (most likely via wastegate solenoid controlling the rate that your internal wastegate vents gasses…this changes the “mood” of a boost car). Why would anyone want this setting?!? Well, because between clutch drops and drifting people have to get to work somehow. This setting makes the STi drive like a 2.5i with 170hp and get 23-24 mpg with no parking lot bucking shenanigans. If you want to get going it still picks up boost and moves but does so with more VW or Audi tact than it’s Mitsubishi Evo peers.

The Sport Sharp (or S#) setting is the old STi of years past we have grown to love (or perhaps a bit snappier). This is the closest thing to an over-indulged project car built by Dr. Frankenstein himself. Revs climb like a 9 pound flywheel attached to a Honda at highschool drags and the wastegate apparently has one setting: BOOOOOOSTT! (and lag below 2k rpms). If “I Mode” left you wanting more for power, this mode makes you realize it’s rally roots.

The normal Sport mode is a nice compromise.  However, we find it more effective to play with either extreme setting on the daily drive. At steady throttle, switching modes is a difference you can feel with your right foot and see on the tach (again, not the placebo effect at work). We find that it’s easier to drop into “S#” from “I Mode” instead of downshifting for mild speed increases.

The serious difference between these modes caters to the mature driver. Obviously Subaru knows that at $35k+tax (depending on options), this buyer profile is less on the impulsive youthful side and more of the mature/seasoned crowd.

We have had a 180 hp Normally Aspirated Impreza 2.5 RS and a 435whp Track-Oriented 1988 Mustang 5.0 with a supercharger.

Finally you can buy a car that excels at either game with PLENTY of room left for upgrades.

PS: The hatchback is definitely love or hate styling. We like it and its starting to grow on us more every day. It’s nice to be able to bring your race rubber to the track in one vehicle and the hatch slightly beats the trunk for this purpose.

We had to transport a table this weekend in the STi…not exactly a sales tactic we think Subaru of America will try to copy anytime soon!

We just took delivery of our 2008 STi hatchback and are already planning the races.

Despite the temptation of going “all out” on the modifications (and having access to the information to do so), we are enjoying the gentle break-in process.  This car drives more European (or Honda) and many Subaru’s of past years.  The rattles and shakes are all but gone.  While I wouldn’t call it an Audi just yet, Subaru is making huge strides.   Expect to see this doing it’s duty at Pacific Raceway during some track/lapping days and an occasional autocross.
The MR2 has only acquired a new nail in it’s tire since the closing of last years race season.   We are planning some local autocross duty and car shows for this car.

I will get some pics up as soon as possible.

There are two distinct groups of people who drive fast: Those with vehicles with traction problems and those who do not have traction problems.

The first category could be something as simple as having far too much power for their drive wheels and a chassis that isn’t up to the task.  A Evo or STi can channel an obscene amount of power via their all wheel drive systems before this ugly problem ever materializes (while drivetrain durability is the first to go at this level).  Rear drive vehicles based on physics alone will have a decent chance at using the power they have as forward momentum.  At the point where traction disappears this power can become reckless for an unskilled driver due to tail-happy shenanigans.  A rear wheel drive car can have over 50 percent of the weight on the drive wheels hence taking the best rules of physics and using them to go fast.  Just because a nose-heavy sport truck and Dodge Viper both spin their rear tires the world treats them quite differently. Front wheel drive poses the greatest limitations again due to physics of weight lifting off of the drive wheels during acceleration and more narrow tread because of fender limitations (you also have to use them to turn).  The benefit to unskilled drivers (and even most skilled drivers) is that while the drive wheels are spinning you lose speed but rarely control of the vehicle.  Onset of massive power and equal traction will lead many front wheel drive cars to torque steer which will cause the vehicle to want to steer into another lane (usually the left).  This is due to most FWD cars having one shorter CV shaft and a chassis designed for economy rather than road racing.

The second category of people who have traction have it for a good reason.  Either they simply do not have enough power to ever upset their chassis or even tires (think stock WRX), or they financed a new Evo/STi/ or other dialed in sports car where the manufacturer spent enough time to figure it out so we didn’t have too.  The minority that didn’t fit into this mold fixed the problem themselves making their car significantly faster and more controlled.

Fixing traction problems: 

1.)  Tires:  Wide tires that look impressive often aren’t.  If you have 500 whp in a mustang (or even 300whp) and are pushing it’s limits your stock radials will be a joke.  If they arent you simply aren’t going fast enough to notice.   Newer cars have sophisticated traction control devices that limit wheel spin for performance sake and almost eliminate the old concept of “feathering the throttle”.  The simple answer to your problem is to get a softer traction compound.  Don’t spend $600+ for some fancy Z-Rated tires that are 13 inches wide because unless they are under 100 tread wear chances are they will be covering your fenders and you will STILL be slow.  Look at some of the R-Compound track tires if the car doesn’t see much rain (or any snow) and assume you will have to buy more sooner than later.  You can also get a set of Drag Radials that will have a similar tread life to the R-Compound track tires but launch a bit harder for straight line purposes and you can take them off for the drive to work.  Wide tires often weigh more than narrow track tires and cause numb steering and handling as well: A car can pull 1 G on the skidpad and feel as nimble as a dump truck.  Tires pressure is a detail but definitely one to deal with when you have the right wheels/tires for your application…it’s like mild suspension tuning.
2.)  Traction Devices:  In a mechanical sense this could be adding a “limited slip differential” to a car with a factory “open differential”.  You hear the word “Posi” or “LSD” to describe this upgrade.  Basically instead of only spinning one tires during loss of traction you will spin two effectively doubling your traction.  Mild limited slips/posi’s will often give a split of about 30-50% of the main drive wheel while aggressive LSD’s or lockers will give 100% traction for both tires.  The more traction the less friendly the car will be to drive with noise, clunking, and steering mannerisms so keep this in mind.

3.)  Suspension:  Strategically increasing spring rates and playing with shock dampening will help you tame the beast.  On double-adjustable suspension systems you really can create the car to do anything you want with the help of adjustable sway bars.  A great example is the Evo 8/9 which is quite nose-heavy but handles amazing due to proper chassis tuning and AWD.  You really can’t compare a Mustang with 60% of the weight on the nose to an Evo with 60% for many reasons.  What you can’t fix at some point is the engineering of the suspension itself and a double-wishbone F/R super car is a lofty goal but difficult to match.  True track cars should be corner-balanced for predictable handling while the rest of us can just slow it down on public roads.
4.)  Chassis tuning:   A lighter more balanced vehicle will handle torque productive fashion.  You can only do so much with an older sedan but anything helps when factions of a second count.  Lighten the car up and pay attention where the weight is coming off of.  Ideally a 50/50 split is perfect for neutral handling but often not achievable.  Front wheel drive cars want this same mix for track sake because going through corners gracefully is better than plowing and hoping traction will close the gap against the stop-watch.
5.)  Drivetrain:  With motor mount inserts, chassis/drivetrain dampers (like the Ingall’s Stiffy Damper), and other devices can help keep your wheel spin under control.  When tires begin to spin often times they begin to bounce and the rebounding process increases exponentially.  Not only does this slow you down but it can destroy your transmission, differential, etc.  When your at this step of stiffening expect nasty daily driving mannerisms like vibrating dash boards…it’s the price you pay for speed.

6.)  Electronic Fixes:  Controlling wheel spin and torque delivery through technology is ideal and not always accessible.  There are companies that offer aftermarket traction control systems but these are hit-or-miss and not attainable for most budgets.  More realistically items like some electronic boost controllers for turbo cars can help limit boost in specific situations (each gear)  to keep your 500 whp under tap in first, second, and then unleash in third-sixth.  TurboXS has a multi-stage manual boost controller that can do the same thing.

7.)  Aero Fixes:  Aerodynamics are a great for increasing handling limits but unless you have a wind-tunnel available and some NASA engineers chances are it will be hit-or-miss and mostly for your own reasons.  It can’t hurt to try but for the money do so for aesthetic reasoning first.  A carbon fiber splitter may help but will definitely hit a few speed bumps along the way.
I know “7″ is a bad way to end a blog.  I could probably organize this for a more concise/orderly “10 Step Process” but am running short on time.  If I remember anything along the way I will edit this post.

There are many other tricks and techniques to tame the beast but most involve learning your car inside and out.  We recommend track days that allow you to drive your vehicle or even local autocrosses.  Learning to drive fast at slower speeds is a better (and cheaper) place to start than learning to drive on a full race track.  The best answer is to just “drive slower on the track” but that’s a cheap answer.  The “less cheap” answer is that good tires will mask the lack of skill that some have and augment the skill of the trained.  If your going to cut corners anywhere DONT do so with tires.  While on that topic, never cut corners simply to make you look faster…when a narrow sticky solution would work better.
Cheers,

Sorry to say we don’t have any racing updates.  If we were into Icelandic rally racing it would be a different story (you never know when we might pick that up!).

The good news is that our project cars aren’t stuck in any snow banks.  Sometimes that is good enough.

You have installed a cold-air intake system, header(s), and full exhaust system but the car seems held back.  Why isn’t it pulling like a VTEC like everyone said it would?

Essentially an engine is an air pump.  You put fuel and air in the cylinders, ignite the combination with a spark, and the result is energy.  Spent gases are shot through the heads, out the header(s), and through your brand new exhaust system.  Now, upgrading the flow of the basic parts such as the intake and exhaust system are great but doesn’t change the breathing characteristics of the engine itself.  If you buy a set of $300 track shoes and hit a marathon you may run better than your $20 Nike knock-offs but you might still flop your hands around and run flat footed the whole way (this is my testimony…not yours!).  What you really did was make the old system more efficient but did not re-invent the wheel.

The more expensive parts make a larger impact on HOW your engine actually responds to the air/fuel/spark flow.  Your computer system should be already done or close on the list before digging deep into the engine.  A race engine with a crappy tune is really just an expensive engine that performs like garbage (and might blow up).

The intake manifold and throttle body are typically designed decently efficient these days.  If you have something older or known to be inefficient (old 5.0 Mustangs, Camaro’s) you can pick up quite a few non-damaging horses for a decent price.  Some Honda’s see gains from these parts and the price makes sense because of how many have been sold (B-series intake manifolds aren’t exactly rare).

The next step and one of the most important is the type of camshaft that you will run.  The camshaft(s) decide how your valves suck in air and expel it.  Engines without variable valve timing can control them to some degree with adjustable cam gears/sprockets.  Some engines are set up pretty well from the factory and while you can see an increase it’s probably more expensive than it’s really worth, such as: Integra Type R, Celica GT-S (or anything with the 2zz-ge), and some turbo cars like the new WRX STi’s.  If you have an older engine the results can be dramatic (like the Mustang/Camaro/Honda guys), or the new cars with old engines like the Evo 8/9 which are basically smog choked.  Much like clutches going too far is often a very BAD thing with cams.  If you drive the car on the street, enjoy idling, and spend less time under 6,000 rpms than over it a full-blown race cam is not what you want.  These usually require extreme engine management and high-end valvetrain/internals to make the difference visible.  However, stepping up to a Stage 1-style cam will bring your power back to the upper rpm where it belongs and often times give you more low/mid range torque as your correcting emission euphoric designs from the factory.  Stage 2-style cams typically add more mid-range to upper power sacrificing a little lower rpm punch and can affect idle characteristics and sometimes give check engine lights.  These will will likely give the most bang-for-the buck and not always require new valve springs or internal engine builds.  The longed for Stage 3-style (and higher) cams are for race vehicles and greatly minimize your low-end torque/power.  If your an autocrosser or street prowler these might give you that Vtec upper rpm pull but you won’t have the economy/torque lobes (unless you have that style of engine) that most Honda/Acura people enjoy.

The people that actually build an engine (especially for normally aspirated power) past the stages above are few and far between.  They may focus on other parts of the car to make a balanced build (drivetrain, suspension, brakes, etc) but digging into the pistons/rods/block of an engine can get pricey and sometimes the built result won’t last long due to some harmonic problems.  It’s often fun to dream about a 10,000 rpm Subaru N/A engine but when you have oiling problems that were never thought of when the engine was stock you can lose $6000 in an afternoon.

For those who preach big-numbers on the internet and “daily” take down Z06 Corvette’s on the track anything but the extreme won’t cut it.  For the rest of us who drive our cars on the street, pass emissions, and want our engines to last longer than a race season it’s wise to cut-back the build to 80% of the dream.

The last 10-20% is where hobby/reality fades away and obsession comes into play.  These are both VERY powerful intents but never appear on the same vehicle.  Know where you are going, learn when to cut your losses, and don’t assume your going to build a “full N/A engine” and then pop a turbo on it later.  Call us if you have any questions.
