Ksport BKAC040-611SO ProComp Big Brake Kit Floating Rotor 6-Piston Caliper

The Ksport BKAC040-611SO ProComp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to deliver superior stopping power and significantly reduce brake fade under sustained high-heat conditions. Designed with caliper options in 4, 6, or 8 piston configurations, this kit integrates advanced brake technology to continuously cool and refresh the brake pad surface during braking.

Caliper Construction:

• One-piece CNC machined billet construction from aerospace-grade aluminum — no casting or welding — delivering uniform strength and corrosion resistance throughout
• Differential bore configuration for optimized clamping force across all piston sizes
• Weighs just over 5 lbs. each, saving significant unsprung weight over OEM calipers
• Machined-in protection grooves for the bridge tubes
• Aluminum pistons for superior heat resistance and consistent operation
• High-temperature seals and stainless-steel brake pad wear plates standard on every caliper
• Opposed piston design greatly improves pad wear evenness and caliper rigidity vs. OEM

Floating Rotor Technology:

• Two-piece floating disc assembly reduces both rotating and unsprung weight
• Floating outer rotor section shifts slightly as needed for better self-centering in the caliper, reducing brake drag and improving performance through more even pad application
• Floating design eliminates thermal stress warping and prevents cupping of the braking surface under extreme heat
• Every rotor is heat treated and balanced before shipment for consistent, reliable performance
• Unique slot design expels gas and pad debris faster than conventional slot patterns while minimizing braking noise

Rotor Style Options:

• Cross Drilled — Runs cooler; recommended for daily-driven street vehicles
• Slotted — Superior heat and gas dispersal without added pad wear; recommended for track-focused and performance driving

Brake Lines & Pads:

• D.O.T. compliant stainless-steel braided brake lines standard — eliminates hose expansion under pressure for a firmer, more responsive pedal feel
• NAOC Ceramic (SC5) street pads included — optimal operating range between 194°F and 1,022°F for fast warm-up under normal driving conditions
• Ceramic pads reduce brake dust by 50% or more compared to race pads and minimize rotor wear and noise

Additional Features:

• Bolt-on installation — minimal tools required, no vehicle modifications needed in most applications
• CNC machined carbon steel caliper brackets included for precise OEM mounting location fitment
• OEM ABS systems remain fully functional
• Available caliper color finishes: Orange, Red, Black, Yellow, and premium anodized options
• Optional Titanium Center Bell and Hardware or Twin Color Anodized Center Bell upgrades available
• 12-month warranty covering manufacturer defects

Whether building a high-performance street car or a dedicated track machine, the Ksport BKAC040-611SO ProComp Big Brake Kit provides a proven, race-developed braking upgrade with the flexibility to match your driving style and performance goals.
