AP Racing PRO 5000 R (9441) Caliper 17mm Pad 152mm Centres


Asymmetrical design which increases the static and real world dynamic stiffness by up to 30%. This is achieved by optimally distributing the body mass of the caliper on the diagonal areas of applied force. Up to 30% lighter than other AP calipers used for competition purposes so unsprung weight is aided.

Price per caliper.
