Racecomp Engineering Yellow springs 2004-2007 WRX STI
The highly anticipated Super Sport Street/Track Springs, an OEM replacement spring for 2004-2007 Subaru WRX STi from Racecomp Engineering. Designed for use with standard STi inverted struts or Ohlins fixed-perch replacement struts, these springs are intended for both the daily driven street driver as well as the autocross and track day weekend warrior.
Racecomp focused on improving on track and autocross performance, while maintaining acceptable ride quality. Extensive research, design, and testing was performed to develop a completely new spring unlike anything currently available. With springs rates increased approximately 25% stiffer then the popular JDM Pink springs, the springs are perfect for those with wider tires worried about rubbing, as well those looking for a little more rear spring rate to promote a more neutral handling characteristic. Much care was taken not to exceed the limits of the stock struts. The mildly progressive design and spring rates properly matched with the dampers ensure that ride quality is not diminished over stock. The car is lowered 20mm in the rear and 23mm in the front for an even look.
When installing these springs, some addtional NVH may be experienced due to increased spring rate.
