TyrolSport revolutionary new Brake Caliper Stiffening bushings prevent the caliper flex inherent in the stock rubber-bushed design. This flex leads to uneven pad wear and rotor deposits under hard usage. An inexpensive way to upgrade the feel/performance of the stock brake system. Track tested and mother approved! 100% stainless steel rings are now standard on all kit.

Note: These bushings do require minimal maintenance. We suggest some lube whenever you rotate your tires and definitely when changing brake pads. If you are a non-involved owner, this product might not be for you. It is targeted to those who want to enhance the performance of their S4 for aggressive street, autocross, and track day use.
