AP Racing PRO 5000 R (9660) Caliper 18mm Pad


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.

Available: In stock


When purchased in quantities of 2 a Left & Right side caliper will be sent. Quantities of 1 unit will need an email sent to us to confirm which caliper side is needed.
