AP Racing CP8350 Brake Kit by Essex

The AP Racing CP8350 Brake Kit by Essex is a motorsport-focused braking upgrade developed for drivers who prioritize braking performance, consistency and thermal control during demanding track use.

At the heart of the system is the AP Racing CP8350 four-piston racing caliper, a proven competition-caliper design that Essex uses across a wide range of vehicle-specific Competition Brake Kits. The CP8350 is part of Essex's Standard Competition range, which uses traditional AP Racing racing calipers rather than the newer Radi-CAL architecture.

Depending on the vehicle application, the CP8350 is paired with a 325mm AP Racing J Hook racing disc. Current Essex kits use a 70-vane disc with a lightweight floating aluminium hat and purpose-designed mounting hardware, providing high thermal capacity and consistent braking performance during extended track sessions.

The complete vehicle-specific kit can also include caliper mounting brackets, stainless-steel brake lines and installation hardware. Brake-pad selection is left to the customer in the competition configuration, allowing the system to be matched to the intended circuit, tire and driving requirements.

A major advantage of the Essex-designed CP8350 system is its focus on maintaining compatibility with the vehicle's OEM master cylinder and ABS system through application-specific piston sizing and hydraulic design. This helps provide predictable pedal feel and braking control without compromising the factory electronic braking systems.

The AP Racing CP8350 Brake Kit by Essex is therefore best suited to performance and track vehicles looking for stronger braking consistency, improved heat management, lightweight hardware and motorsport-level braking performance. Exact disc size, mounting configuration and vehicle compatibility depend on the specific application.
