Subaru WRX/STi

  • Solo 2 Stock Class Level II

    This final stage maximizes your impact within the autocross stock class. In fact, after theses modifications combined with level I, anyone except the most hard-core SCCA motor heads would deem your car far from stock. Rest assured that dodging cones, on the open track, or driving to work your vehicle will far exceed anything the manufacturer had intended.

    Koni Sport Shocks

    These multi-point adjustable sport absorbers at max settings provide much more aggressive dampening for your stock spring limitations. {For those with more suspension tuning experience and less fear of fabrication, we have the Koni 8611 double adjustable inserts. These high-end absorbers are used by nearly every nationally competitive stock class vehicle for unsurpassed fine tuning since compression and rebound can be adjusted separately. This allows for maximum spring rate since legally in stock class you cannot change the springs themselves. Contact us for instructions on measuring properly for these Koni 8611 inserts.}

    Cobb Tuning 3 Cat-Back Exhaust

    This is not only one of the best performing Subaru exhaust systems in the world but it beats all other competitors in: quality, sound, and appearance. This is built entirely of T304 stainless steel and mandrel bends. The muffler features a conventional looking polished stainless muffler with a classy double-walled stainless 3.5” tip. This has a deep respectful tone unlike nearly every other muffler on the market. It does not drone at highway speeds and gives a sporty rumble under wide open throttle. We cannot say enough good things about this system.

    Cobb Street Brake Pads (front)

    Designed for street use, COBB Tuning’s Street Formula Brake Pads are the best balance of performance pad without excessive noise, brake dust, or rotor wear. A brake pad’s job is to create friction on the brake rotor to help slow the vehicle down, and COBB’s Street Formula pad excels when both cold and hot. Well suited for autocross competition and aggressive street driving – they have a very linear torque response to give you the confidence you need to brake later and dive deeper into the corners. When you’re looking for a suitable upgrade over the factory brake pads, look no further than COBB’s Street Formula Brake Pad.

    Koni 8611 Double Adjustable Race Inserts

    Please call or email to substitute your standard Koni Sport Struts for Koni 8611 Strut Inserts straight from Koni’s race division. For packages not including struts due to availability, these are universal fitment and should work assuming proper measurement and fabrication.

    Standard Koni Sport dampers are multiple point rebound adjustable and a great upgrade from stock or for managing lowered vehicles (in other autocross classes). They are rebuildable and revalvable for many different situations and can even be converted to double adjustable for a charge.

    Koni 8611’s are double-adjustable (rebound and compression) that are very popular amongst autocross and track racers in North America. They have all of the features of the standard Sport strut but because you can adjust greater compression rates they can act as race springs for classes that only allow strut replacements. These do require proper measuring and in some cases fabrication to fit original strut housing but for those who wish to fabricate they give a serious performance advantage. These struts are seen in MANY top national competing vehicles. These are not for those looking for a slightly firmer ride who autocross twice a year.

    These cost $259.95 each ($1039.80 / set): an additional $329.80 over the Koni Sport Struts for the WRX.

    There are no standard Koni Sports available for the STi, a set of 8611’s would add an additional $1039.80 to your package price.

    If you have any questions about measurement, pricing, or if these are recommended for your specific situation...please contact us via phone or email prior to purchasing.
