Key Features / Product Warranty
Race Spec rear brake system for the B5 Audi chassis, fits both A4 and S4 cars, features:
- Solid steel 300x25mm rotors (12")
- Rear pad set, Polymatrix-H compound for road racing use
- Billet aluminum brake caliper brackets, including high grade bolts for caliper to carrier
- DOT stainless steel brake lines with metric adapters to stock hard lines on control arms
- 4-piston Wilwood Powerlite Calipers, fully rebuildable with many pad options
We built this affordable high quality kit for the hard core track car and for our own Time Attack A4. Stock S4 rear calipers are heavy and flex, for a race car the parking brake mechanism is also not needed. We strongly recommend adjustable brake bias when installing this kit, especially if you do not have ABS.
Note, this brake kit has no provision for emergency brakes, users who would like to retain some sort of e-brake functionality can install a line lock or an additional caliper on the rotor.
Available without brake rotors, or with lightweight 2-piece rotors with aluminum hats that shave 3.5 pounds off of each rotor. Please select option below.
