Ksport BKMZ014-445CO DualComp Rear 4-Piston Big Brake Kit with 14 in. Drilled Rotors

The Ksport BKMZ014-445CO DualComp Big Brake Kit is a complete all-in-one dual caliper brake upgrade engineered for drivers who demand independent foot brake and handbrake control from a single caliper assembly. Designed with drifting and rally racing in mind, the DualComp system is also Formula Drift legal and delivers serious stopping performance on both the street and the track.

How the DualComp System Works:

• Utilizes a single 4-piston caliper — 2 pistons dedicated to the foot brake circuit and 2 pistons dedicated to the handbrake circuit
• Each circuit operates completely independently on its own hydraulic system
• Includes a polished titanium handbrake cylinder and lever for improved aesthetics and precise handbrake control
• CNC-machined carbon steel caliper brackets allow the larger calipers to bolt directly to OEM bracket locations

Rotor & Hardware Highlights:

• Rotor diameter: 356 mm (14 in.) — Cross Drilled style
• Two-piece floating rotor design with a 6061-T6 aircraft-grade aluminum center bell for significantly reduced rotational mass
• Rotors commonly weigh up to 50% less than OEM rotors of the same size
• Floating outer ring expands and contracts independently, greatly reducing the risk of heat-related warping
• D.O.T.-compliant stainless-steel braided brake lines included — stop expansion under pressure for a firmer, more responsive pedal feel

What's Included:

• 4-Piston DualComp Calipers
• Floating Brake Disc (Drilled)
• Brake Pads
• Handbrake Cylinder & Lever
• CNC Caliper Brackets
• Stainless-Steel Braided Brake Lines
• All required installation hardware

This is a complete bolt-on big brake kit — no vehicle modifications are required in most applications. Backed by Ksport's 12-month manufacturer defect warranty.
