Firm Up Rear Roll Control On Your Twin Sixty Six Chassis
The factory rear sway bar mount bushings on the BRZ, FR-S, and 86 platform are built soft for a comfortable ride, but that softness allows the bar to shift under load, delaying roll resistance exactly when you need it most in a corner. This Whiteline KSK106-18 18mm bushing kit replaces the factory mount bushing with a firmer compound that keeps the rear sway bar located precisely, sharpening turn in response and reducing body roll.
