Ksport BKMZ050-445CO DualComp Rear 4-Piston Big Brake Kit with 14 in. Drilled Rotors

The Ksport DualComp Big Brake Kit is a complete, high-performance rear braking solution engineered for demanding motorsport applications including drifting and rally racing. At the heart of this system is a single 4-piston caliper with a clever dual-circuit design: two pistons dedicated to the foot brake and two pistons dedicated to the handbrake, each operating independently on its own hydraulic circuit for precise, reliable brake control in any situation.

Key Features:

• Dual-Circuit 4-Piston Caliper — Foot brake and handbrake circuits run fully independent of one another within a single compact caliper body
• 14 in. (356mm) Drilled Floating Rotor — Two-piece design with a 6061-T6 aircraft-grade aluminum center hat reduces rotational mass and aids heat dissipation
• Lightweight Rotor Construction — Two-piece floating rotors commonly weigh up to 50% less than OEM rotors of equivalent size, improving pedal response and reducing brake fade
• Polished Titanium Handbrake Cylinder and Lever — Enhances the look and feel of the handbrake while providing positive control of vehicle movement
• CNC Machined Carbon Steel Caliper Brackets — Precision-machined adapters allow the oversized calipers to bolt directly to the factory caliper bracket location with no chassis modifications required
• DOT-Compliant Stainless Steel Braided Brake Lines — Included as standard for improved pedal feel and long-term durability
• Formula Drift Legal — Approved for use in competitive Formula Drift and rally racing events
• Fits 18-inch Wheels and Above
