The Subaru WRX/STI/BRZ requires the Whiteline Rear Camber Adjusting Kit to be able to adjust the rear end camber settings. This kit for the Scion FR-S includes high durometer upper control arm bushings and cam bolts that allow for on car adjustment of +/-.75° of camber (depending on ride height). The increased adjustment will also enable experienced suspension tuners to increase camber for improved handling performance. Sold as a pair.
