Description

The Ksport Dualcomp 4-Piston Rear Big Brake Kit is engineered to deliver exceptional braking control for drifting, rally racing, and high-performance street applications. Its unique dual 4-piston caliper configuration separates the foot brake and handbrake functions, providing precise modulation and competitive-level performance. The kit is Formula Drift legal, making it an ideal choice for dedicated motorsports enthusiasts seeking a reliable and high-performing rear braking system. This system boasts lightweight forged one-piece calipers finished in a bold orange color for a race-inspired aesthetic. The 14-inch two-piece slotted rotors are designed to improve heat dissipation and enhance pad bite under demanding conditions. Both the caliper and rotor hats are constructed from aerospace-grade 6061-T6 aluminum, contributing to reduced rotational mass for faster brake response. Durability is ensured through high-temperature seals, titanium brake pad retainer clips, and stainless steel wear plates. Installation of this big brake kit is considered hard and is recommended for experienced enthusiasts or professional installers. While drilling is not required, it is essential to note that 18-inch or larger wheels are necessary to ensure proper caliper clearance. The kit includes dual 4-piston calipers, 14-inch slotted two-piece rotors, brake pads, a handbrake assembly, stainless steel brake lines and fittings, and all necessary installation hardware. This Ksport Dualcomp 4-Piston Rear Big Brake Kit with 14-Inch Slotted Rotors is specifically designed to fit the 2015-2023 Ford Mustang EcoBoost models.
