Ksport BKAU051-445CO DualComp Rear 4-Piston Big Brake Kit with 14 in. Drilled Rotors

The Ksport DualComp Big Brake Kit is a purpose-built, all-in-one dual-function braking solution engineered for performance driving. Designed with drifting and rally racing in mind, this rear big brake kit features an innovative single 4-piston caliper that serves dual duty — two pistons dedicated to the foot brake and two pistons dedicated to the handbrake, each operating independently on its own hydraulic circuit.

Key Features:

• 4-Piston Dual-Function Caliper: Two pots handle the foot brake; two pots handle the handbrake, each running independently for precise, conflict-free braking control
• 14-Inch (356mm) Drilled Floating Rotor: Two-piece rotor design with a drilled iron outer ring and a 6061-T6 aircraft-grade aluminum center hat, reducing rotational mass by up to 50% compared to OEM rotors
• Two-Piece Floating Rotor Design: The outer ring can expand and contract independently from the center section, significantly reducing the risk of heat-induced warping
• CNC Machined Carbon Steel Caliper Brackets: Precision-machined mounting hardware ensures accurate fitment and consistent caliper alignment
• Formula Drift Legal: Tested and proven on drift circuits and rally stages; compliant for Formula Drift competition use
• Complete Bolt-On Kit: Includes calipers, floating brake disc, brake pads, handbrake hardware, and all required installation hardware — no vehicle modifications required in most applications
• 12-Month Warranty: All Ksport Big Brake Kits are covered by a 12-month manufacturer defect warranty

The DualComp system is designed for straightforward installation with minimal tools required. The lightweight aluminum center sections also function as heat sinks, dissipating thermal energy away from the rotor and hub assembly faster than traditional one-piece steel rotors. Compatible with 18-inch wheels and above.
