Ksport BKVO031-621CO Floating Brake Rotor for Big Brake Kit Systems

The Ksport BKVO031-621CO is a high-performance floating brake rotor designed for use with Ksport big brake kit systems, compatible with 4, 6, or 8 piston caliper configurations. Engineered to deliver exceptional stopping power while resisting the thermal stresses associated with aggressive braking, this rotor is an ideal upgrade for performance-focused builds.

Two-Piece Floating Disc Design

Ksport's 2-piece floating disc assembly significantly reduces both rotating and unsprung weight. The floating design allows for thermal expansion during extreme heat cycles, preventing disc warping and eliminating cupping of the braking surface — a critical advantage during sustained high-performance or track use.

Key Features:

• Floating rotor construction absorbs thermal stress and prevents disc warping under extreme heat
• Unique slot design reduces braking noise and expels gas and pad debris faster than conventional slot patterns
• Heat treated and balanced prior to shipment for consistent, reliable performance
• Reduced rotating and unsprung mass via lightweight two-piece disc assembly
• Compatible with 4, 6, and 8 piston Ksport calipers for flexible brake system configuration
• Engineered to minimize brake fade and maintain consistent pad surface refresh under repeated braking

Slotted Rotor Technology

The proprietary slot design on this rotor is optimized to expel combustion gases and brake pad debris from the friction surface more efficiently than standard slot configurations, maintaining a clean contact patch between pad and rotor. This design is particularly suited to track and performance driving applications where thermal loads are consistently elevated.

Every Ksport rotor undergoes heat treatment and precision balancing before leaving the facility, ensuring smooth, vibration-free operation from the first brake application. The BKVO031-621CO pairs seamlessly with Ksport's CNC-machined billet aluminum calipers featuring aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates for a complete, performance-grade brake system.
