Ksport BKVW052-444CO DualComp Rear Big Brake Kit with Drilled Floating Rotor - 4-Piston

The Ksport DualComp Big Brake Kit is a race-engineered, all-in-one rear braking solution designed for performance driving enthusiasts. Built with drifting and rally racing in mind, the DualComp system features a single 4-piston caliper with a clever dual-function design: two pistons dedicated to the foot brake and two pistons dedicated to the handbrake, each operating independently on its own hydraulic circuit.

At the heart of the system is a lightweight two-piece floating brake disc. The center section is crafted from 6061-T6 aircraft-grade aluminum, which dramatically reduces rotational mass for sharper brake response. Because the outer rotor ring can expand and contract independently from the aluminum center, heat-induced warping is significantly reduced. Rotor weight is commonly up to 50% less than OEM rotors of the same diameter.

The DualComp system also includes a polished titanium handbrake cylinder and lever, delivering both a premium look and precise handbrake control for competition or spirited street use. CNC-machined carbon steel caliper brackets allow the oversized calipers to bolt directly to the factory caliper bracket location with no permanent vehicle modifications required in most applications.
