Overview

The AP Racing by Essex Radi-CAL Competition Brake Kit with ENP (electroless nickel plated) calipers is a front brake upgrade for the McLaren MP4-12C, 650S, 570S, 600LT and 720S. It pairs AP Racing CP9661 Radi-CAL Pro5000R racing calipers with 394 x mm AP Racing J Hook discs on fully floating aluminum hats, built for track days and competition driving. Clears OEM wheels without a spacer.

Why upgrade

Weighs within a few lbs. per side of the OEM carbon ceramic system, without the expense and headaches of CCM. The ENP (electroless nickel plated) finish is very durable and easy to clean. The caliper takes pads from all major pad manufacturers. Every component is designed to resist the heat of extended track sessions. Pistons are sized to work seamlessly with the OEM master cylinder and ABS. It works with the OEM rear brakes or a matching AP Racing rear kit.

Caliper and disc construction

On the McLaren 720S, 650S, 12C, the CP9661 caliper mounts radially on a dedicated bracket. The caliper uses a commonly available 18mm thick pad shape. Ventilated, domed-back stainless steel pistons keep heat out of the brake fluid for a very firm pedal. Anti-knockback springs behind the caliper pistons limit pad knockback. Stainless steel caliper hardware gives a long service life even with frequent pad changes. There are no dust boots to burn up at track temperatures. The championship-winning 84-vane AP Racing J Hook discs are fully floating. The discs use anti-knockback, anti-rattle attachment hardware.
