Ksport BKHD010-621CO Procomp Big Brake Kit 12 in. Cross Drilled Floating Rotor 6-Piston

The Ksport BKHD010-621CO Procomp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to deliver dramatically enhanced stopping power and superior resistance to brake fade. Featuring a 12-inch (304mm) two-piece cross drilled floating rotor and available in 4, 6, or 8-piston caliper configurations, this kit is purpose-built for street performance and spirited track use.

Floating Rotor Technology:

• Two-piece floating disc design allows the outer ring to shift slightly during braking, enabling better self-centering in the caliper
• Reduces brake drag and promotes more even pad application for consistent stopping force
• Floating disc construction prevents thermal stress from warping the disc or cupping the braking surface under extreme heat
• Two-piece assembly significantly reduces both rotating and unsprung weight compared to OEM rotors

Caliper Construction:

• CNC machined from a single solid billet of aircraft-grade aluminum — never cast or welded — for uniform thickness and long-term strength
• Opposed-piston design improves pad wear and caliper rigidity over OEM brake assemblies
• Weighs just over 5 lbs. each, with machined-in protection grooves for bridge tubes
• Aluminum pistons with high-temperature seals for reliable operation at elevated temperatures
• Stainless-steel brake pad wear plates included as standard

Rotor and Pad Performance:

• Cross drilled rotors dissipate heat efficiently and are recommended for daily-driven performance vehicles
• Unique slot pattern expels gas and pad debris faster than conventional designs while reducing braking noise
• Every rotor is heat treated and precision balanced prior to shipment
• NAOC Ceramic brake pads deliver optimal street and occasional track performance with an operating range of 194°F–1022°F
• Ceramic compound reduces brake dust by 50% or more compared to race pads

Hardware and Lines:

• D.O.T.-compliant stainless-steel braided brake lines included as standard — resist expansion under pressure for a firmer, more responsive pedal feel
• CNC machined carbon steel caliper brackets included
• Complete bolt-on system with no vehicle modifications required in most applications

Warranty: All Ksport Big Brake Kits are covered by a 12-month manufacturer defect warranty. Kits are built to order — please allow 4–6 weeks for production and delivery.
