Description
Track-Ready Rear Braking. The Ksport Supercomp 4-Piston Rear Big Brake Kit with 14-Inch Slotted Rotors 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. It is specifically designed for 2WD Mustang GT models without the Performance Pack and V6 applications.
Construction and Appearance. This kit 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 improve heat dissipation and help reduce rotor warping during repeated high-heat cycles. CNC-machined aerospace-grade 6061-T6 aluminum components and aluminum pistons with high-temperature seals ensure durability and reliable braking performance.
Installation. Installation is considered hard and is best suited for experienced enthusiasts or professional technicians. Drilling is not required, and the system is designed as a direct bolt-on upgrade.
Warranty. This brake kit is backed by a one-year limited warranty.
Application. This Ksport Supercomp 4-Piston Rear Big Brake Kit with 14-Inch Slotted Rotors fits 2015-2023 Mustang EcoBoost models.
