AP Racing Brakes and Pro5000R Motorsport Calipers

Shop AP Racing braking components for track-day and motorsport applications. AP Racing is one of the key names in competition braking, and our current range focuses on genuine AP Racing fluid and Pro5000R calipers that can form the basis of a serious big brake conversion or motorsport brake package.

AP Racing Pro5000R CP9660 Six-Piston Calipers

For high-performance front brake conversions, browse our AP Racing Pro5000R CP9660 options. These include the AP Racing CP9660 six-piston caliper pair in anodised finish and the AP Racing CP9660 six-piston caliper pair in nickel finish.

A caliper should never be selected on piston count alone. A complete brake conversion also needs the correct disc diameter and thickness, bell and bracket design, pad shape, hydraulic compatibility and wheel clearance. If you are building an AP Racing package for a specific BMW, Porsche or other track car, confirm those system dimensions before ordering individual calipers.

AP Racing Brake Fluid

Brake fluid is another important part of a reliable track braking system. Our range includes AP Racing R1 brake fluid and AP Racing R DOT 5.1 brake fluid. Fluid choice should match the braking temperatures and service intervals of the vehicle.

Build a Complete Track Brake Package

For repeated circuit use, plan the caliper, disc, pad, fluid, hose and cooling package together. Correct pad shape and wheel clearance are especially important when combining AP Racing calipers with vehicle-specific brackets and two-piece discs.
