Ksport BKBM130-841SO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper

The Ksport BKBM130-841SO is a performance big brake kit featuring a floating rotor design and your choice of 4, 6, or 8 piston caliper configurations. Engineered to deliver the ultimate in stopping power, this system integrates advanced brake technology to dramatically reduce brake fade while continuously cooling and refreshing the brake pad surface under heavy braking conditions.

Caliper Design & Construction:

• Extreme lightweight one-piece caliper in a differential bore configuration
• CNC machined from aircraft-grade billet aluminum
• Weighs just over 5 lbs. per caliper for reduced unsprung weight
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons with high-temperature seals for reliable performance under extreme heat
• Stainless steel brake pad wear plates standard on every caliper
• Opposed piston caliper design improves pad wear evenness and caliper rigidity over OEM
• Stainless steel braided brake lines prevent expansion under pressure for consistent pedal feel

Floating Rotor Design:

• Two-piece disc assembly reduces both rotating and unsprung weight
• Floating disc design prevents thermal stress warping and eliminates cupping of the braking surface under extreme heat
• Unique slot pattern reduces braking noise and expels gas and pad debris faster than conventional designs
• Every rotor is heat treated and precision balanced before shipment for optimal performance
• Cross-drilled rotors run cooler — ideal for daily-driven vehicles
• Slotted rotors recommended for track-oriented or high-performance applications

Installation:

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

The Ksport BKBM130-841SO big brake kit delivers race-proven braking technology in a package suitable for both spirited street driving and dedicated track use. The combination of a floating rotor, lightweight billet caliper, and stainless hardware ensures consistently powerful, fade-resistant braking performance.
