6-Piston Caliper Kit with 2-Piece Slotted Rotors

The Ksport Procomp Big Brake Kit offers a significant upgrade in stopping power and performance for your vehicle. This kit integrates advanced brake technology to reduce brake fade and maintain optimal pad surface under demanding conditions. The calipers are constructed from aircraft-quality billet with a differential bore configuration, weighing just over 5 lbs. each. Standard features include aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates, ensuring durability and consistent performance. The opposed piston design enhances pad wear and caliper rigidity compared to OEM systems, while stainless steel brake lines prevent expansion under pressure. The kit incorporates a 2-piece floating disc assembly, which reduces both rotating and unsprung weight. This design also mitigates thermal stresses from extreme heat, preventing rotor warping or cupping of the braking surface. Every rotor is heat-treated and balanced for peak performance. This particular kit (BKSB210-611CO) features 6-piston ProComp calipers in an orange finish, 286mm (11.3-inch) diameter rotors with a slotted style, and is designed for front axle fitment. The application is specifically for the 2015-2016 Subaru WRX models equipped with the 2.0L H4 GAS DOHC Turbocharged engine.
