Ksport BKHD021-621CO Floating Rotor Big Brake Kit Piston Caliper - 4/6/8

The Ksport BKHD021-621CO Big Brake Kit delivers serious stopping performance with a floating two-piece rotor design and your choice of 4, 6, or 8 piston caliper configurations. Engineered to dramatically reduce brake fade, this system continuously cools and refreshes the brake pad surface during aggressive braking — making it well-suited for both spirited street use and track applications.

Caliper Features:

• CNC machined from aircraft-grade billet aluminum in a lightweight one-piece construction
• Differential bore configuration for optimized clamping force and pad wear
• Opposed piston design improves caliper rigidity and pad wear compared to OEM
• Aluminum pistons with high-temperature seals for fade resistance
• Stainless-steel brake pad wear plates included as standard
• Machined-in bridge tube protection grooves
• Each caliper weighs just over 5 lbs.

Rotor Features:

• Two-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design prevents thermal stress warping and braking surface cupping under extreme heat
• Unique slot design expels gas and pad debris faster than conventional slot patterns, reducing brake noise
• Every rotor is heat treated and balanced prior to shipment for consistent performance
• Cross-drilled rotors run cooler and are recommended for daily-driven vehicles
• Slotted rotors are recommended for track-focused use

System Highlights:

• Stainless-steel braided brake lines prevent hose expansion under pressure for a firm, consistent pedal feel
• Minimal tool installation in most applications
• Available caliper options: 4, 6, or 8 piston configurations

The Ksport BKHD021-621CO big brake kit is a complete, performance-engineered braking upgrade designed to outperform OEM systems in heat management, pedal response, and long-term pad wear — whether on the street or the track.
