SPC Performance 05-10 Scion tC Rear Control ArmThis fixed change arm is ideal for correcting excessive negative camber issues seen in lowered Scion tC's. The Scion tC comes from the factory with a cam bolt that provides + 1. 25deg. This factory change is not enough change for lowered applications. By increasing the length of the rear upper control arm SPC Performance adds 2deg positive camber to the rear suspension that can then be dialed in with the OEM cam bolt.
