The SuperPro master vehicle kit for the 2013 Scion FR-S (also for Subaru BRZ and Toyota 86) is a chassis upgrade in one box that replaces front control arm and steering rack bushings and adds rear control arm and subframe supplement bushings to improve precision and feedback. Supplement insert bushings avoid full subframe replacement while delivering most of the performance benefit, improving turn-in, cornering grip and consistency across the chassis.
