Eliminate Front Lower Control Arm Deflection on Your 86 Platform Car
The factory rubber front lower control arm bushings on the Scion FR-S, Subaru BRZ, and Toyota 86 allow the control arm to flex under hard cornering, dulling steering feedback and introducing unwanted camber and toe change. The SuperPro SPF3877K polyurethane bushing kit replaces the fore and aft inner bushings with a firmer polyurethane compound, tightening up control arm location for sharper turn-in and more consistent handling.
Key Features
- SPF3877K polyurethane bushing kit replaces the front lower control arm fore and aft inner bushings
- Reduces control arm deflection under cornering and braking loads
- Improves steering precision and reduces unwanted camber/toe change
- Direct fit replacement for the factory rubber bushings
- Polyurethane compound resists wear far longer than factory rubber
