Ksport BKSB100-621CO Floating Brake Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper

The Ksport BKSB100-621CO is a high-performance floating rotor big brake kit engineered to deliver exceptional stopping power for demanding street and track applications. Available with 4, 6, or 8 piston caliper configurations, this system offers scalable braking performance to match your specific driving needs.

Ksport's 2-piece floating disc assembly significantly reduces both rotating and unsprung weight while eliminating thermal stress transfer that can cause disc warping or braking surface cupping under extreme heat. The unique slot design on the rotor minimizes braking noise and expels gas and pad debris more efficiently than conventional slot patterns. Every rotor is heat treated and balanced prior to shipment to ensure consistent, reliable performance right out of the box.

Key Features:

• Floating rotor design — prevents thermal stress warping and braking surface cupping during high-heat use
• 2-piece disc assembly — reduces rotating and unsprung weight for improved handling
• 4, 6, or 8 piston caliper options — choose the configuration suited to your performance requirements
• CNC-machined aircraft-grade billet caliper — weighing just over 5 lbs. each for maximum strength with minimal weight
• Differential bore caliper configuration — promotes even pad wear across the full pad surface
• Aluminum pistons with high-temperature seals and stainless-steel brake pad wear plates included as standard
• Opposed piston caliper design — improves pad wear and caliper rigidity over OEM brake systems
• Stainless-steel braided brake lines — eliminate hose expansion under pressure for consistent pedal feel
• Unique slot rotor design — reduces brake noise and expels gas and pad debris faster than conventional designs
• Heat treated and balanced rotors — every unit processed before shipment for optimal performance
• Designed for easy installation with minimal tools required in most applications

Ksport big brake kits are engineered to significantly reduce brake fade and continually cool and refresh brake pad surfaces under repeated hard braking. The opposed piston design provides greater caliper rigidity and more consistent pad contact than stock OEM setups, making this kit an ideal upgrade for both high-performance street use and track days.
