AP Racing by Essex Competition Brake Kits (Track/Race)


When you're fighting for tenths of a second on track, having a brake system that provides confidence is of paramount importance. Essex Designed AP Racing Competition Brake Kits are designed to make you go faster, period. When daily driving requirements take a back seat to lower lap times, our Competition Kits are the perfect fit.

Our Essex Designed AP Racing Competition Kits come in two flavors:

Our Standard Competition Kits use traditional AP Racing calipers like the one on the left above, whereas our Radi-CAL Competition Kits use AP's latest generation of cutting-edge Radi-CAL calipers (shown on the right).

The precise specification of each systems varies by application, but standard features for both the Standard and Radi-CAL Competition Kits include:

  • Carefully chosen piston sizes for proper brake bias and seamless integration with OEM master cylinder & ABS systems
  • Front-only kits are designed to mate perfectly with OEM rear brake components
  • Durable anodized aluminum calipers with stainless steel pistons and anti-knockback springs
  • High vane count, directional brake discs, with floating or fixed aluminum hats depending on application
  • Lightweight, anodized aluminum caliper mounting brackets
  • Spiegler stainless steel brake lines included with every kit
  • All associated mounting bolts, hardware, and detailed installation instructions
