Ksport BKBM072-621CO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper Options

The Ksport BKBM072-621CO is a two-piece floating rotor big brake kit engineered to deliver superior stopping power with reduced brake fade, improved thermal management, and long-lasting pad life. Available with 4, 6, or 8 piston caliper configurations, this system is designed for enthusiasts who demand more than OEM braking performance.

Caliper Design & Construction:

• Extreme lightweight one-piece differential bore caliper CNC machined from aircraft-grade billet aluminum
• Each caliper weighs just over 5 lbs, minimizing unsprung weight
• Opposed piston design improves pad wear evenness and caliper rigidity versus OEM calipers
• Machined-in protection grooves for bridge tubes
• Aluminum pistons with high-temperature seals for reliable performance under extreme heat
• Stainless-steel brake pad wear plates included as standard

Rotor Design & Technology:

• Two-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design isolates thermal stresses, preventing warping or cupping of the braking surface under extreme heat
• Unique slot design rapidly expels gas and pad debris while reducing braking noise
• Every rotor is heat treated and balanced before shipment for optimal performance consistency
• Cross-drilled rotors run cooler and are suited for daily-driven applications; slotted rotors are recommended for track-focused use

Brake Lines & Hardware:

• Stainless-steel braided brake lines resist expansion under pressure for consistent, firm pedal feel
• Designed for straightforward installation with minimal tools required in most applications

The Ksport big brake system continuously cools and refreshes the brake pad surface during braking, making it an ideal upgrade for performance street and track-day vehicles seeking maximum braking confidence and reduced fade.
