Nickel Finish AP Racing PRO 5000 R (9449) 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.

Nickel-plated coatings excel in safeguarding materials against both corrosion and wear. Electroless nickel plating (ENP)  finds widespread use in various applications, where it serves to prolong the lifespan of components, making it the ideal metal plating method for brake calipers. These calipers are routinely subjected to challenging conditions, including extreme temperatures, such as scorching heat and freezing cold, as well as environmental factors like summer humidity, winter frost, snow, and road salt. As such, the implementation of a corrosion-resistant coating on brake calipers holds paramount importance in guaranteeing the endurance of the vehicle’s braking system.

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.
