TyrolSport Rigid Caliper Stiffening Kit - B8 A4 / S4 / A5 / S5
The TyrolSport Rigid Caliper Slider kit (RCS) is the newest addition to our solid brake bushing family. Machined in the USA from 954 Bronze alloy, these bushings are a precision fit to all Audi B8 front brake calipers (A4, S4, A5, S5). Caliper deflection is greatly reduced over the stock rubber bushings, allowing for even pad wear and increased brake pedal response. Our new bushing design glides freely along 303 stainless steel pins and secures with stainless snap-rings. Rubber boots reused from the stock bushings round off the RCS kit and extend maintenance intervals beyond each brake job.
