Ksport BKAU190-621CO Floating Brake Rotor or Piston Caliper Compatible Big Brake Kit - 4 6 8

The Ksport BKAU190-621CO is a high-performance floating brake rotor designed as part of Ksport's big brake kit system, delivering exceptional stopping power with significantly reduced brake fade. The two-piece floating disc assembly minimizes both rotating and unsprung weight while allowing the rotor face to move independently, preventing thermal stress from extreme heat from warping the disc or cupping the braking surface.

Rotor Features:

• Two-piece floating disc assembly reduces rotating and unsprung weight
• Floating disc design prevents thermal warping and braking surface cupping under extreme heat
• Unique slot design expels gas and pad debris faster than conventional slot patterns
• Every rotor is heat treated and balanced prior to shipment for consistent, reliable performance
• Compatible with 4-piston, 6-piston, and 8-piston caliper configurations

Caliper Compatibility & System Highlights:

• Designed for use with Ksport's extreme lightweight one-piece, differential bore calipers
• CNC machined from aircraft-grade billet aluminum — each caliper weighs just over 5 lbs.
• Opposed piston caliper design improves pad wear and caliper rigidity versus OEM
• Machined-in protection grooves for bridge tubes
• Aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates standard
• Stainless-steel brake lines resist expansion under pressure

Slotted vs. Cross-Drilled Guidance:

• Cross-drilled rotors run cooler and are recommended for daily-driven vehicles
• Slotted rotors are recommended for vehicles with frequent track or performance use

Ksport big brake components are engineered for straightforward installation with minimal tools required in most applications. Continual cooling and refreshing of the brake pad surface during braking helps maintain consistent performance lap after lap or stop after stop.
