Description
AP Racing Custom Racing Brake Caliper | High Performance Brake Upgrade
Introducing our custom racing brake caliper from AP Racing including models CP8560, CP8530, CP8521, and CP8520 — a high‑performance brake upgrade built for demanding road and track applications. These calipers are designed for precision braking performance, superior heat management, and responsive modulation under extreme conditions.
The lineup includes 4‑piston and 6‑piston variants tailored to different performance goals and brake disc capacities. Whether upgrading for competitive racing, track use, or high‑end road performance, this caliper set delivers consistent and reliable braking power beyond standard systems.
The 4‑piston versions like CP8530 and CP8560 are optimized for large diameter discs and provide improved clamping force and pedal feel for high‑speed braking scenarios. Each piston ensures even pressure across the brake pad surface, reducing uneven wear and enhancing friction performance.
For greater braking performance, the 6‑piston CP8520 and CP8521 configurations increase piston area and clamping force, ideal for heavier vehicles or aggressive driving. These calipers provide more uniform pressure over larger pad areas, yielding higher friction efficiency and dynamic stability during repeated high‑load braking events.
Each variant is manufactured from high‑strength forged aluminium alloy, offering an optimal balance of light weight and rigidity. Reducing unsprung mass improves vehicle dynamics and response while maintaining structural integrity under extreme temperature and stress conditions.
