Supercomp 4-Piston Rear Big Brake Kit

The Ksport Supercomp 4-Piston Rear Big Brake Kit is designed to deliver superior stopping power for demanding street and track use. This rear brake system features larger calipers, rotors, and pads than Ksport's Procomp kits, providing enhanced thermal capacity and consistent braking performance even under aggressive driving conditions. Construction includes lightweight, one-piece forged calipers finished in a bold orange for a race-inspired look. The 14-inch (356mm) full-floating, two-piece slotted rotors are engineered to improve heat dissipation and resist warping during repeated high-heat cycles. The kit utilizes CNC-machined aerospace-grade 6061-T6 aluminum components and aluminum pistons with high-temperature seals for durability and reliable operation. Installation of this big brake kit is considered hard, requiring mechanical expertise or professional installation. The system is designed as a direct bolt-on upgrade, and drilling is not required. The kit includes two 4-piston calipers, two 14-inch slotted full-floating two-piece rotors, a set of brake pads, stainless steel brake lines, and all necessary mounting brackets and hardware. A one-year limited warranty backs this brake kit. This Ksport Supercomp 4-Piston Rear Big Brake Kit is specifically designed to fit 2011 to 2014 Ford Mustang GT models without the Performance Pack, and V6 models. It is important to note that Ksport Big Brake kits are designed for 2WD vehicles only, unless otherwise stated, and the OEM handbrake will not function with this kit.
