Product Description
The AP Racing CP9668 caliper pair is an endurance-focused Pro 5000 R setup designed for braking systems where consistency, heat capacity and pad life are critical. Compared with the AP Racing CP9660, the CP9668 uses a deeper 25mm brake pad, providing more friction material volume for longer sessions, heavier vehicles and repeated high-temperature use.
The six-piston design delivers exceptional clamping force with excellent pedal feel, while the forged aluminium caliper body provides outstanding stiffness without unnecessary weight. The larger 25mm pad format not only increases braking consistency but also extends service intervals by reducing brake pad wear during demanding use.
The CP9668 platform also benefits from one of the widest selections of motorsport brake pad compounds available, including PAGID Racing, Ferodo, PFC and Raybestos, allowing drivers to tailor braking performance for fast road, sprint racing, endurance racing or dedicated track day use.
Whether you're building a custom brake conversion or upgrading an existing motorsport brake package, the AP Racing CP9668 remains one of the most respected endurance calipers available.
