Ksport BKMS021-971SO Supercomp Big Brake Kit Front 8-Piston 16.6 in. Slotted Rotors

The Ksport BKMS021-971SO Supercomp Big Brake Kit is Ksport's most extreme brake upgrade, engineered to deliver the highest level of stopping power with larger-diameter rotors and more aggressive caliper design — all without requiring any vehicle modifications to install. This sophisticated bolt-on big brake kit builds on the ProComp platform with larger calipers, bigger rotors, increased piston count, and standard full-floating two-piece rotor assemblies for superior performance on both street and track.

SuperComp Calipers

• Forged one-piece construction from a solid billet of aerospace-grade aluminum — not cast or welded — for perfectly even wall thickness and elimination of weak spots
• Differential bore configuration with larger pistons than the ProComp series for increased clamping force
• Opposed piston design significantly improves pad wear consistency and caliper rigidity over OEM designs
• Aluminum pistons with heavy-duty, high-temperature seals rated for racetrack operating temperatures
• Stainless steel brake pad wear plates standard on every caliper
• Machined-in protection grooves for the bridge tubes
• Each caliper weighs just over 7 lbs., minimizing unsprung and rotating mass
• Available in standard painted finishes (Orange, Red, Black, Yellow) or premium anodized and polished upgrades

Two-Piece Floating Rotor Assembly

• Standard full-floating two-piece disc design reduces both rotating and unsprung weight — rotors can weigh up to 50% less than OEM rotors of the same size
• Floating outer ring allows slight self-centering in the caliper, reducing brake drag and improving even pad application
• Floating design prevents thermal stress from extreme heat, stopping disc warp and braking surface cupping
• Unique slot pattern expels gas and pad debris faster than conventional designs while significantly reducing brake noise
• Every rotor is heat-treated and balanced before shipment
• Available in Cross Drilled (recommended for street/daily driving — runs cooler) or Slotted (recommended for track use)

Brake Lines & Pads

• D.O.T.-compliant stainless-steel braided brake lines included — stop line expansion under pressure for a quicker, firmer pedal feel vs. stock rubber lines
• Ksport SC5 Street Pads (NAOC Ceramic) included as standard — optimal for street and occasional track use with operating temperatures between 194°F–1,022°F
• SC5 pads reduce brake dust by 50% or more compared to race pads and minimize rotor wear and noise

CNC Caliper Brackets & Hardware

• CNC-machined carbon-steel caliper brackets included — allows the oversized calipers to bolt directly to the OEM caliper bracket location with no modifications
• Complete kit includes calipers, floating brake disc, brake pads, stainless braided brake lines, brackets, and all required hardware

Customization Options

• Titanium Center Bell and hardware upgrade available
• Twin Color Anodized Center Bell upgrade available
• Premium high-polish caliper finishes available in Silver, Gold, and Titanium
