Ksport BKAC021-611CO Supercomp Big Brake Kit Floating Rotor Piston Caliper - 4/6/8

The Ksport BKAC021-611CO Supercomp Big Brake Kit delivers a significant upgrade in stopping power over the factory brake system. Engineered to dramatically reduce brake fade while continuously cooling and refreshing the brake pad surface during aggressive braking, this bolt-on big brake kit is built for both street and track performance demands.

Aircraft-Grade Billet Calipers

Each caliper is CNC machined from a single billet of aircraft-quality aluminum — never cast or welded — providing perfectly even wall thickness and superior structural rigidity throughout. At just over 5 lbs. each, these calipers are a dramatic weight savings over OEM units. The opposed-piston caliper configuration greatly improves pad wear evenness and overall caliper rigidity. Machined-in protection grooves shield the bridge tubes, and the differential bore design further optimizes braking force distribution. Available in 4, 6, or 8 piston configurations to suit your performance goals.

Full-Floating 2-Piece Rotor Assembly

The kit utilizes a 2-piece floating disc assembly that reduces both rotating and unsprung weight. The floating outer ring is designed to shift slightly as needed, allowing for better self-centering in the caliper, which lowers brake drag and delivers more even pad application. This floating design also prevents thermal stress from extreme heat warping the disc or cupping the braking surface. Every rotor is heat treated and dynamically balanced before shipment to ensure optimal, vibration-free performance from day one.

Rotor Style Options

• Cross-Drilled Rotors — Run cooler than slotted designs; recommended for daily-driven vehicles
• Slotted Rotors — Ksport's unique slot pattern expels gas and pad debris faster than conventional designs, reducing braking noise; recommended for track or high-performance use
