Ksport BKAU081-444SO DualComp Rear 4-Piston Big Brake Kit with 14 in. Slotted Rotors

The Ksport DualComp Big Brake Kit is a complete all-in-one dual caliper braking solution engineered for performance driving applications including drifting and rally racing. The DualComp system uses a single 4-piston caliper with a split-function design: two pistons dedicated to the foot brake and two pistons dedicated to the handbrake, each operating independently on its own hydraulic circuit.

Key Features:

• Dual-Function 4-Piston Caliper — 2 pistons for foot brake, 2 pistons for handbrake, each on independent hydraulic systems
• 14-Inch Slotted Floating Rotor — Two-piece design with 6061-T6 aircraft-grade aluminum center hat for reduced rotational mass
• Lightweight Rotor Construction — Two-piece rotors commonly weigh up to 50% less than OEM one-piece rotors of the same size
• Reduced Warp Risk — Outer rotor ring floats independently from the aluminum center, allowing thermal expansion without distortion
• D.O.T.-Compliant Stainless-Steel Braided Brake Lines — Included as standard for reliable, fade-resistant brake feel
• CNC-Machined Carbon Steel Caliper Brackets — Bolt directly to OEM caliper bracket locations with no vehicle modifications required
• Formula Drift Legal — Tested and approved for competition use on drift and rally circuits
• 12-Month Warranty — Covers manufacturer defects
