Ksport BKFD050-621CO Floating Brake Rotor for Big Brake Kit

The Ksport BKFD050-621CO is a floating brake rotor designed for use with Ksport's big brake kit systems, compatible with 4, 6, or 8 piston caliper configurations. Engineered for serious performance applications, this 2-piece disc assembly reduces both rotating and unsprung weight compared to traditional single-piece rotor designs.

The floating disc design is a critical performance advantage — it allows the outer rotor ring to move independently of the hat, preventing thermal stress from extreme heat from warping the disc or cupping the braking surface. This is especially valuable in high-heat track environments where conventional rotors are prone to distortion.

Key Features:

• Floating 2-Piece Design: Reduces rotating and unsprung weight while managing thermal expansion under extreme braking conditions
• Unique Slot Pattern: Proprietary slot geometry reduces braking noise and expels gas and pad debris more effectively than conventional slot designs
• Heat Treated & Balanced: Every rotor is heat treated and precision balanced before shipment for consistent, reliable performance
• Compatible Calipers: Designed for use with 4, 6, or 8 piston Ksport caliper options
• Reduced Brake Fade: The rotor design works in concert with Ksport's big brake system to continuously cool and refresh the pad surface during braking

Ksport big brake kits are engineered for easy installation in most applications, requiring minimal tools. The system pairs this floating rotor with CNC-machined aircraft-grade billet calipers featuring aluminum pistons, high-temperature seals, stainless-steel brake pad wear plates, and stainless-steel brake lines that resist expansion under pressure. The opposed piston caliper design delivers improved pad wear and greater caliper rigidity over OEM setups.

The BKFD050-621CO floating rotor is an ideal upgrade for performance and track-driven vehicles where thermal management and consistent stopping power are paramount.
