Overview
GR86/FRS/BRZ solid aluminum subframe bushings replace the stock mushy rubber bushings to eliminate free play of the subframe relative to the chassis. This prevents the subframe from "bouncing around" under drivetrain torque or suspension load, maintaining optimum suspension geometry and reducing wheel hop.
