Overview

The AP Racing by Essex Rally Competition Brake Kit is a front brake upgrade for the 2002-2021 Subaru Impreza WRX, WRX STI and WRX. It pairs AP Racing CP8350 racing calipers with 299 x 32mm, 60-vane AP Racing J Hook discs on fully floating aluminum hats, built for track days and competition driving. Designed to fit behind 15 inch wheels used in many stage rally applications.

Why upgrade

Eliminates several pounds of unsprung weight compared to the OEM brakes. The caliper takes a 20mm thick pad for long life and heat tolerance. It works with the OEM rear brakes.

Caliper and disc construction

On the Subaru WRX, STI, the CP8350 caliper mounts radially on a dedicated bracket at 152mm centers with a 44mm offset, with an M10x1.0 inlet thread. The anodized caliper finish resists wear and deterioration at high temperatures. 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. Pads change with one bolt, with no caliper removal. The championship-winning 60-vane AP Racing J Hook discs are fully floating. The disc metallurgy is designed for the temperatures seen on track, for a long service life. Spiegler stainless steel brake lines with a clear sheath reduce compliance compared with the OEM rubber lines.

299 x 32mm, 60-vane J Hook discs on floating hats
