Ksport BKAC010-611CO Procomp Big Brake Kit 11.3 in. Cross Drilled Floating Rotor 6 Piston

The Ksport BKAC010-611CO Procomp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to significantly enhance stopping power under sustained high-heat conditions. Featuring a 286mm (11.3 in.) two-piece floating cross-drilled rotor and a choice of 4, 6, or 8 piston caliper configurations, this kit delivers measurable improvements in fade resistance, pedal feel, and overall braking performance over OEM setups.

Lightweight Two-Piece Floating Rotor Design:

The floating rotor uses a two-piece disc assembly that reduces both rotating and unsprung weight. The outer rotor section is designed to shift slightly as needed, allowing for better self-centering in the caliper, which lowers brake drag and promotes more even pad application. This floating design also eliminates thermal stress buildup that can warp a solid disc or cup the braking surface during extreme heat cycles. Every rotor is heat treated and balanced before shipment to ensure consistent, reliable performance.

Aircraft-Grade Billet Aluminum Calipers:

• One-piece CNC-machined construction from a solid billet of aircraft-grade aluminum — not cast or welded — for uniform wall thickness, maximum strength, and corrosion resistance
• Aluminum pistons provide superior heat resistance and maintain consistent operation at elevated temperatures
• Differential bore configuration with machined-in bridge tube protection grooves
• Opposed piston design improves pad wear consistency and increases caliper rigidity compared to OEM floating caliper designs
• High-temperature seals and stainless-steel brake pad wear plates included as standard

DOT-Compliant Stainless-Steel Braided Brake Lines:

Included stainless-steel braided brake lines are DOT compliant and eliminate the hose expansion found in OEM rubber lines under hard braking, resulting in a firmer, more responsive pedal feel and quicker brake application.

Cross Drilled Rotor Style:

The cross-drilled rotor style is recommended for daily-driven vehicles, as drilled rotors tend to run cooler than slotted designs by allowing heat to dissipate more effectively. For vehicles that see heavier track use, a slotted rotor variant is also available.
