Ksport BKAC030-444CO DualComp Rear Big Brake Kit 4-Piston Caliper 14 in. Drilled Rotor

The Ksport DualComp Big Brake Kit is a complete all-in-one dual-function brake upgrade engineered for performance driving applications, including drifting and rally racing. At the heart of the system is a single 4-piston caliper that serves a dual purpose: 2 pistons dedicated to the foot brake and 2 pistons dedicated to the handbrake, each operating independently on its own hydraulic circuit for precise, reliable brake modulation.

Key Features:

• Dual-function 4-piston caliper — integrates foot brake and handbrake into one compact unit
• Floating two-piece rotor design — outer ring expands and contracts independently from the 6061-T6 aircraft-grade aluminum center hat, dramatically reducing warping from heat buildup
• Lightweight construction — rotors commonly weigh up to 50% less than OEM rotors of the same size, reducing rotational mass and improving response
• Cross drilled rotor — promotes cooler running temperatures, ideal for street-driven or daily-driven vehicles
• Formula Drift legal — tested and validated on professional drift and rally circuits
• Complete bolt-on kit — minimal tools required; no permanent vehicle modifications needed in most applications
• 12-month warranty covering manufacturer defects

Kit Includes:

• 4-Piston DualComp Caliper(s)
• Floating Brake Disc (Rotor)
• Brake Pads
• Handbrake hardware
• All required installation hardware

Important Notes:

• OEM handbrake will not function after installation — the Ksport DualComp handbrake system replaces it
• Ksport Big Brake kits are designed for 2WD vehicles only unless otherwise stated
• Kits are built to order — please allow 4–6 weeks for production and delivery

The Ksport DualComp Big Brake Kit delivers fade-free stopping power, superior heat management, and race-proven performance in a single, streamlined brake package.
