Ksport BKSB110-621CO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper

The Ksport BKSB110-621CO is a high-performance big brake kit featuring a floating rotor design available with your choice of 4, 6, or 8 piston caliper configurations. Engineered to deliver maximum stopping power while dramatically reducing brake fade, this system continuously cools and refreshes the brake pad surface during hard braking events.

Caliper Design & Construction:

• One-piece monobloc caliper CNC machined from aircraft-grade billet aluminum
• Differential bore configuration for optimized pad contact and even wear
• Weighs just over 5 lbs. per caliper for significant unsprung weight reduction
• Machined-in bridge tube protection grooves for added structural integrity
• Aluminum pistons with high-temperature seals for reliable performance under extreme heat
• Stainless steel brake pad wear plates included on every caliper
• Opposed piston design improves pad wear and caliper rigidity over OEM calipers

Rotor Features:

• 2-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design eliminates thermal stress warping and prevents cupping of the braking surface under extreme heat
• Unique slot design reduces braking noise and expels gas and pad debris more efficiently than conventional slot patterns
• Every rotor is heat treated and balanced prior to shipment for consistent, reliable performance

Brake Lines:

• Stainless steel braided brake lines resist expansion under pressure for a firm, consistent pedal feel

Installation:

• Designed for easy installation with minimal tools required in most applications

Ksport big brake kits are built for both street and track performance. Cross-drilled rotors run cooler and are ideal for daily-driven vehicles, while slotted rotors are better suited for applications that see frequent track use. This kit delivers the braking confidence and thermal management demanded by performance and motorsport applications.
