Ksport BKVW260-445CO DualComp Rear 4-Piston Big Brake Kit with 14 in. Drilled Rotors

The Ksport BKVW260-445CO DualComp Big Brake Kit is an all-in-one rear brake upgrade engineered for high-performance driving. Designed with drifting and rally racing in mind, this system features a unique dual-function 4-piston caliper where 2 pistons operate the foot brake and 2 pistons operate the handbrake — each running independently on its own hydraulic circuit.

The DualComp system includes a polished titanium handbrake cylinder and lever, delivering precise handbrake modulation that is essential for drift and motorsport applications. CNC-machined carbon steel caliper brackets are included, allowing the larger-than-OEM calipers to mount directly to the factory caliper bracket location without vehicle modifications in most applications. DOT-compliant stainless-steel braided brake lines are also included as standard.

Two-Piece Floating Rotor Technology:

• 356mm (14 in.) drilled rotor — rear position
• Two-piece floating rotor design provides lightweight, fade-free braking performance on the track and comfortable daily-use operation
• Rotors commonly weigh up to 50% less than OEM rotors of the same size
• Lightweight center sections crafted from 6061-T6 aircraft-grade aluminum reduce rotational mass for faster brake response
• Outer rotor ring expands and contracts independently from the center hat, significantly reducing the risk of warping under heat
• Aluminum center sections act as heat sinks, dissipating thermal energy away from the hub assembly
