4-Piston Red Caliper with 356mm Slotted Rotor

The kit features a lightweight ProComp 4-piston caliper, machined from aircraft-quality billet and finished in a striking red color. The caliper has a differential bore configuration and includes advanced features like aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates, which contribute to improved pad wear and caliper rigidity. Complementing the caliper are 356mm slotted rotors, designed in a 2-piece floating assembly to reduce unsprung weight and prevent warping from extreme heat. The unique slot design on the rotors also helps to reduce braking noise and efficiently expel gases and pad debris. Furthermore, the kit incorporates stainless steel brake lines, which are crucial for preventing hose expansion under pressure, ensuring consistent and firm pedal feel. The Procomp system is built to integrate new brake technology, effectively reducing brake fade and continually cooling the brake pad surface during braking. This makes it an ideal choice for drivers who experience frequent high-demand braking scenarios. Application for this specific kit (BKAU031-442SO) is noted for the 8L Chassis, specifically for Euro 1996-2003 Audi A3 Quattro models. A critical note for this kit is that the OEM handbrake will not function after installation.
