Ksport BKMS021-951SO Supercomp Front 8-Piston Big Brake Kit with 15 in. Slotted Rotors

The Ksport BKMS021-951SO Supercomp Big Brake Kit is Ksport's most extreme bolt-on brake upgrade, engineered to deliver the highest level of stopping power without requiring any vehicle modifications. Featuring an 8-piston front caliper paired with 15-inch two-piece floating slotted rotors, this big brake kit is a significant step up from the ProComp series with larger calipers, more pistons, and increased rotor and pad surface area for maximum braking performance.

Supercomp Caliper Design:

• One-piece forged construction — machined from a solid billet of aerospace-grade aluminum rather than cast or welded, eliminating weak spots that lead to fracturing, warpage, or failure
• 8-piston opposed configuration — greatly improves pad wear and caliper rigidity over OEM sliding caliper designs
• Aluminum pistons with heavy-duty, high-temperature seals designed to handle racetrack temperatures
• CNC machined carbon-steel caliper brackets allow the oversized calipers to bolt directly to OEM caliper bracket locations with no modifications required
• Caliper finish options include standard painted colors (Orange, Red, Black, Yellow) or premium upgrades in Silver, Gold, Titanium, and Glassy/Hard Anodized finishes

Two-Piece Floating Rotor System:

• 15-inch (380mm) slotted rotor with a floating outer ring that self-centers in the caliper, reducing brake drag and improving pad contact consistency
• Rotors can weigh up to 50% less than OEM rotors of the same size, reducing both rotating and unsprung mass
• Floating design isolates thermal stresses to prevent disc warping or braking surface cupping under extreme heat
• Unique slot pattern expels gas and pad debris efficiently while minimizing brake noise
• Optional upgrade to Titanium Center Bell and Hardware or Twin Color Anodized Center Bell available for further customization

Included Components:

• Front 8-piston Supercomp calipers
• 15-inch two-piece floating slotted brake rotors
• SC5 Street / NAOC Ceramic brake pads — optimized for street and occasional track use
• D.O.T. compliant stainless-steel braided brake lines — eliminate expansion under pressure for firmer pedal feel and quicker response vs. stock rubber lines
• CNC machined carbon-steel caliper mounting brackets
• All required hardware and owner's manual

Rotor Style Guide: Slotted rotors are recommended for vehicles that see frequent track use, where aggressive pad compounds and high heat cycles are common. For primarily street-driven applications, the cross-drilled rotor option is also available and runs cooler under normal daily driving conditions.

This system is designed for use with 19-inch wheels and larger. The Ksport Supercomp Big Brake Kit comes backed by a 12-month warranty covering manufacturer defects.
