2-Piston Big Brake Kit with Vented Rotors

The KSport ProComp Big Brake Kit is engineered as a complete rear brake upgrade for drivers seeking enhanced stopping power, particularly under sustained high-heat conditions typical of performance and racing applications. The calipers are crafted from a single piece of aircraft-grade aluminum, ensuring exceptional strength, light weight, and resistance to corrosion. They feature a 2-piston opposed-piston design to maximize pad grip and minimize uneven wear. The aluminum caliper pistons offer superior heat resistance and are immune to corrosion. Complementing the calipers are 2-piece vented rotors, available in drilled and slotted styles, designed to manage heat effectively and improve braking response. The rotors utilize a 2-piece construction with an aluminum center to reduce rotational mass and a design that minimizes the chance of warping. This kit includes heavy-duty caliper seals for sustained high-temperature use and stainless steel brake lines that prevent expansion under extreme conditions, leading to a firmer pedal feel and faster response. The kit requires a minimum wheel diameter of 15 inches (381mm) to ensure proper clearance. The ProComp kit is specifically designed for the 2009-2013 Volkswagen Golf GTI. The package contains two ProComp Big Brake Kits, intended for rear axle installation.
