Ksport BKBM011-621CO Procomp Big Brake Kit 12 in. Cross Drilled Rotor with 4, 6, or 8 Piston Caliper Options

The Ksport BKBM011-621CO is a high-performance floating brake rotor designed as part of Ksport's big brake kit system, compatible with 4, 6, or 8 piston caliper configurations. Engineered for drivers who demand maximum stopping power, this rotor integrates advanced braking technology to significantly reduce brake fade while continuously cooling and refreshing the brake pad contact surface under heavy braking loads.

Two-Piece Floating Disc Design:

The Ksport floating rotor uses a 2-piece disc assembly that reduces both rotating and unsprung weight. The floating disc design isolates thermal stresses caused by extreme heat, preventing disc warping and cupping of the braking surface — a common failure point in traditional one-piece rotor designs.

Key Features:

• Floating disc construction — absorbs thermal expansion to eliminate heat-induced warping
• Unique slot design — reduces braking noise and expels gas and pad debris faster than conventional slot patterns
• Heat treated and balanced — every rotor is heat treated and precision balanced before shipment for consistent, optimal performance
• Reduced rotating and unsprung mass — 2-piece assembly design lowers overall wheel assembly weight for improved handling response
• Compatible with 4, 6, or 8 piston calipers — flexible configuration options to suit a range of performance braking setups
• Caliper compatibility — pairs with Ksport's CNC-machined aircraft-grade billet aluminum calipers featuring aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates

Rotor Type Guidance:

• Cross-drilled rotors tend to run cooler and are recommended for daily-driven street vehicles
• Slotted rotors are recommended for vehicles that see more track use than daily street driving

Designed for easy installation with minimal tooling required in most applications, the Ksport BKBM011-621CO floating rotor delivers the stopping performance and thermal management demanded by performance enthusiasts and track-day drivers alike.
