Overview

The AP Racing by Essex Radi-CAL Competition Brake Kit is a high-performance braking system designed for enhanced stopping power and heat management. This front kit features CP9668 Radi-CAL six-piston calipers with an Electroless Nickel Plated (ENP) finish, known for its durability and resistance to wear and deterioration at elevated temperatures. The kit includes 372x34mm, 72-vane AP Racing J Hook racing discs, which are fully floating and utilize a 12-attachment point system to the hat.

Engineered for demanding driving conditions, the calipers incorporate 25mm thick brake pads, ventilated stainless steel pistons to manage heat, and anti-knockback springs for a firm pedal feel. The kit also comes with Spiegler stainless steel brake lines, offering reduced compliance compared to OEM rubber lines. This system provides an approximate 12 lb reduction in unsprung weight compared to OEM BMW brakes. Brake pads are not included, allowing users to select their preferred racing compound.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
