Ksport BKAC030-611SO Procomp Big Brake Kit 11.3 in. Slotted Floating Rotor 6 Piston

The Ksport BKAC030-611SO Procomp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to deliver significantly enhanced stopping power under sustained high-heat conditions. Featuring an 11.3-inch (286mm) slotted floating rotor and available in 4, 6, or 8 piston caliper configurations, this kit is a direct, no-modification-required upgrade over the factory brake system in most applications.

Aircraft-Grade Billet Aluminum Calipers

Each caliper is CNC machined from a single solid billet of aircraft-grade aluminum — never cast or welded — delivering perfectly even wall thickness throughout for maximum strength and corrosion resistance. The one-piece construction weighs just over 5 lbs. each and incorporates a differential bore configuration, machined-in protection grooves for the bridge tubes, and an opposed piston layout that greatly improves pad wear and caliper rigidity over OEM designs. Aluminum pistons with high-temperature seals and stainless-steel brake pad wear plates are standard on every caliper.

Floating Two-Piece Rotor Design

Ksport utilizes a two-piece floating disc assembly that reduces both rotating and unsprung weight. The floating outer section shifts slightly as needed, allowing for better self-centering in the caliper, which lowers brake drag and improves braking through more even pad application. This floating design also prevents thermal stresses from warping the disc or cupping the braking surface under extreme heat. Every rotor is heat treated and balanced before shipment for consistent, reliable performance.

Slotted Rotor Technology

The unique slot pattern on the rotor continuously cleans and refreshes the pad surface, reduces braking noise, and expels gas and pad debris more efficiently than conventional slot designs. Slotted rotors are recommended for vehicles that see frequent track use. Cross-drilled rotors, which tend to run cooler, are the preferred choice for daily-driven applications.

DOT-Compliant Stainless-Steel Braided Brake Lines

D.O.T.-compliant stainless-steel braided brake lines are included standard. These lines eliminate expansion under pressure, delivering a firmer pedal feel and quicker pedal response compared to stock rubber lines.
