Product Description
The AP Racing CP9668-3S7L is an endurance-focused Pro 5000 R caliper designed for braking systems where consistency, heat capacity and pad life are critical. Compared with the AP Racing CP9660, the CP9668 platform uses a deeper 25mm brake pad, providing more friction material volume for longer sessions, heavier cars and repeated high-temperature use.
The six-piston design delivers strong clamping force with excellent pedal control, while the forged aluminium body helps maintain stiffness under heavy braking loads. The CP9668-3S7L also supports a wide range of motorsport pad compounds, allowing the braking system to be tailored for fast road, track day, sprint, endurance or competition use.
When paired with the correct opposite-hand caliper, discs, caliper brackets, brake lines and pads, the CP9668-3S7L is a proven choice for building a serious AP Racing big brake kit or upgrading an existing motorsport brake package.
