Ksport BKHD051-621CO Big Brake Kit Floating Rotor 4, 6, or 8 Piston Caliper

The Ksport BKHD051-621CO Big Brake Kit delivers a significant upgrade in stopping performance over factory brake systems. Engineered to dramatically reduce brake fade while continuously cooling and refreshing the brake pad surface under hard braking, this kit is a proven solution for both spirited street driving and track use.

At the heart of the system is a one-piece CNC-machined caliper crafted from aircraft-grade billet aluminum in a differential bore configuration. Weighing just over 5 lbs. each, these lightweight calipers feature machined-in protection grooves for the bridge tubes. The opposed-piston caliper design delivers superior pad wear and caliper rigidity compared to OEM designs, and is available in 4, 6, or 8 piston configurations to match your performance requirements.

Key Features:

• Floating 2-piece rotor assembly reduces both rotating and unsprung weight while preventing thermal stress from warping the disc or cupping the braking surface
• Aluminum pistons with high-temperature seals and stainless-steel brake pad wear plates standard on every caliper
• Unique slot design reduces braking noise and expels gas and pad debris faster than conventional slot patterns
• Every rotor is heat treated and balanced before shipment for consistent, reliable performance
• D.O.T.-compliant stainless-steel braided brake lines eliminate hose expansion under pressure for a firmer, more responsive pedal feel
• Available in cross-drilled or slotted rotor styles — cross-drilled recommended for daily-driven vehicles; slotted recommended for track-focused applications
• Bolt-on installation with minimal tools required in most applications — no vehicle modifications needed
• Covered by Ksport's 12-month manufacturer defect warranty

The floating rotor outer section is designed to shift slightly as needed, allowing for better self-centering in the caliper, which lowers brake drag and promotes more even pad application. Two-piece rotor construction commonly results in rotors weighing up to 50% less than OEM rotors of the same diameter. Compatible with all OEM ABS systems.
