Supercomp 4-Piston Rear Big Brake Kit

The Ksport Supercomp 4-Piston Rear Big Brake Kit is engineered to deliver increased stopping power for high-performance street and track use. Featuring larger calipers, rotors, and pads compared to Procomp kits, this system enhances thermal capacity and braking consistency under aggressive driving conditions. Construction includes lightweight forged one-piece calipers finished in a bold orange color for a race-inspired aesthetic. The 14-inch (356mm) full-floating two-piece slotted rotors are designed to improve heat dissipation and help reduce rotor warping during repeated high-heat cycles. The components are CNC-machined from aerospace-grade 6061-T6 aluminum and feature aluminum pistons with high-temperature seals for durability and reliable braking performance. Installation is considered hard and is best suited for experienced enthusiasts or professional technicians. Drilling is not required, as the system is designed as a direct bolt-on upgrade. 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 mounting brackets with hardware. This brake kit is backed by a one-year limited warranty. This Ksport Supercomp 4-Piston Rear Big Brake Kit is specifically designed for 2WD Mustang GT models without the Performance Pack and V6 applications. It fits 2015-2023 Mustang EcoBoost models, requiring a minimum 18-inch wheel size.
