Ksport BKSB010-621CO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper

The Ksport BKSB010-621CO Floating Rotor Big Brake Kit is a high-performance, bolt-on brake upgrade engineered to deliver maximum stopping power while dramatically reducing brake fade under sustained high-heat conditions. Available with your choice of 4, 6, or 8 piston caliper configurations, this kit integrates modern brake technology to continuously cool and refresh the brake pad surface during heavy braking.

Caliper Construction:

• Extreme lightweight one-piece caliper CNC machined from aircraft-grade billet aluminum — weighs just over 5 lbs. each
• Differential bore configuration for optimized pad contact and even wear
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons for superior heat resistance and uncompromised operation
• High-temperature seals rated for extreme braking environments
• Stainless-steel brake pad wear plates standard on every caliper
• Opposed piston design improves pad wear consistency and caliper rigidity over OEM

Rotor and Disc Assembly:

• 2-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design prevents thermal stress warping and eliminates braking surface cupping under extreme heat
• Unique slot design expels gas and pad debris faster than conventional slot patterns, greatly reducing braking noise
• Every rotor is heat treated and balanced before shipment for optimal performance
• Available in cross-drilled (recommended for daily-driven vehicles) or slotted (recommended for track/performance use) rotor styles

Brake Lines and Hardware:

• DOT-compliant stainless-steel braided brake lines prevent expansion under pressure for firmer, more responsive pedal feel
• Complete kit includes calipers, floating brake disc, brake pads, brake lines, and all required hardware
• Designed for easy bolt-on installation with minimal tools required in most applications
