Ksport BKFD250-621CO Floating Brake Rotor | 4, 6, or 8 Piston Caliper Compatible

The Ksport BKFD250-621CO is a high-performance floating brake rotor designed as part of Ksport's big brake kit system, delivering superior stopping power and dramatically reduced brake fade under demanding driving conditions. The two-piece floating disc assembly reduces both rotating and unsprung weight, while the floating design absorbs thermal stresses generated during extreme braking — preventing disc warping and braking surface cupping.

Advanced Rotor Design:

• Floating two-piece disc assembly minimizes rotating and unsprung weight for improved handling response
• Thermal stress relief through floating hardware prevents warping and cupping from extreme heat cycles
• Unique slot design expels brake gas and pad debris faster than conventional slotted rotors, reducing braking noise
• Heat treated and precision balanced prior to shipment for consistent, reliable performance
• Compatible with 4, 6, or 8 piston caliper configurations

Caliper System Highlights (when paired with Ksport calipers):

• CNC machined from aircraft-grade billet aluminum — weighs just over 5 lbs. each
• Differential bore, opposed-piston design improves pad wear evenness and caliper rigidity over OEM
• Aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates standard
• Machined-in bridge tube protection grooves for long-term durability
• Stainless-steel brake lines resist expansion under pressure for consistent pedal feel

Installation: Designed for straightforward installation with minimal tools required in most applications. Compatible with Ksport big brake kit configurations using 4, 6, or 8 piston calipers.

Slotted rotor designs like this one are best suited for vehicles that see frequent track use or spirited driving, where aggressive thermal management is a priority. For primarily street-driven vehicles, Ksport also offers cross-drilled rotor options that tend to run cooler under lighter daily use conditions.
