Ksport BKSB110-611SO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper Options

The Ksport BKSB110-611SO is a premium big brake kit engineered to deliver maximum stopping power for performance and track-oriented applications. Featuring a floating 2-piece disc assembly, this system significantly reduces unsprung and rotational weight while allowing the rotor to expand and contract freely under extreme heat — eliminating thermal warping and braking surface cupping.

The kit is available with 4, 6, or 8 piston caliper configurations, each CNC machined from aircraft-grade billet aluminum in an opposed-piston, differential bore design. At just over 5 lbs. each, these lightweight monoblock calipers feature machined-in bridge tube protection grooves, aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates for consistent, fade-resistant performance. The opposed piston layout greatly improves pad wear evenness and caliper rigidity over stock OEM calipers.

Key Features:

• Floating 2-piece rotor design — absorbs thermal stress to prevent warping and surface cupping
• Unique slotted rotor design — minimizes brake noise and expels gas and pad debris more efficiently than conventional slot patterns
• Heat treated and balanced rotors — every rotor is heat treated and dynamically balanced before shipment for peak performance
• Cross-drilled rotor option — runs cooler, ideal for street and daily-driven vehicles
• Slotted rotor option — optimized for track and performance driving applications
• Stainless-steel braided brake lines — resist expansion under pressure for a firmer, more consistent pedal feel
• CNC-machined billet aluminum calipers — aircraft-quality construction, available in 4, 6, or 8 piston configurations
• Aluminum pistons with high-temp seals — reduce heat transfer and maintain seal integrity under racing conditions
• Reduced brake fade — innovative design continuously cools and refreshes pad surface during braking
• Easy installation — designed for straightforward fitment with minimal tooling required on most applications

The Ksport BKSB110-611SO big brake kit is an ideal upgrade for enthusiasts seeking a significant improvement in braking performance over OEM systems. Whether used on the street or the track, this kit provides the stopping confidence and thermal management needed for demanding driving conditions.
