Product Details

The Ksport BKBM115-961SO SuperComp Big Brake Kit is Ksport's most extreme brake upgrade, engineered to deliver the highest level of stopping power with larger-diameter rotors, more pistons, and increased pad surface area over their ProComp series. This sophisticated bolt-on system installs with minimal tools and requires no vehicle modifications in most applications.

SuperComp Caliper Design:

  • Forged one-piece caliper machined from a solid billet of aircraft-grade aluminum — not cast or welded — for perfectly uniform wall thickness and elimination of weak spots
  • Differential bore configuration with larger pistons than the ProComp series for maximum clamping force
  • Aluminum pistons with heavy-duty, high-temperature seals rated for racetrack conditions
  • Stainless steel brake pad wear plates standard on every caliper
  • Opposed piston design improves pad wear evenness and caliper rigidity over OEM calipers
  • Machined bridge tube protection grooves for added durability
  • Weighs just over 7 lbs. each for significant unsprung weight reduction

Two-Piece Floating Rotor Assembly:

  • Standard floating two-piece disc assembly reduces both rotating and unsprung weight — rotors can weigh up to 50% less than OEM equivalents
  • Floating outer ring self-centers in the caliper to minimize brake drag and promote even pad application
  • Floating design dissipates thermal stress to prevent disc warping and braking surface cupping under extreme heat
  • Unique slot pattern expels gas and pad debris faster than conventional designs while significantly reducing braking noise
  • Every rotor is heat treated and precision balanced before shipment
  • Available in Cross Drilled (recommended for daily-driven vehicles) or Slotted (recommended for track-focused use)

Additional Kit Features:

  • CNC machined carbon-steel caliper brackets for direct bolt-on fitment to OEM caliper bracket locations
  • D.O.T.-compliant stainless-steel braided brake lines eliminate hose expansion under pressure for a firmer, more responsive pedal feel
  • NAOC ceramic brake pads included for optimal street and occasional track performance
  • Caliper finish options include painted Orange, Red, Black, and Yellow as standard; premium Silver, Gold, Titanium, and anodized colors available as upgrades
  • Optional Titanium Center Bell and hardware or Twin Color Anodized Center Bell available for further customization

Kit Includes: SuperComp calipers, two-piece floating brake disc, brake pads, D.O.T.-compliant stainless steel brake lines, CNC caliper brackets, and all required installation hardware.

Backed by a 12-month warranty covering manufacturer defects, the Ksport SuperComp Big Brake Kit is built to order and represents the pinnacle of Ksport's brake engineering for both street performance and track use.
