Ksport BKSC080-621CO Procomp Big Brake Kit with Floating Rotor - 12 in. Drilled - 6 Piston

The Ksport BKSC080-621CO Procomp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to deliver significantly enhanced stopping power under sustained high-heat conditions. Featuring advanced brake technology throughout, this kit is designed to reduce brake fade and continuously cool and refresh the brake pad surface during repeated braking events — making it an ideal upgrade for both aggressive street driving and occasional track use.

Caliper Construction:

• Extreme lightweight one-piece caliper machined from a solid billet of aircraft-grade aluminum — no casting or welding
• Differential bore configuration for optimized pad contact and clamping force
• Each caliper weighs just over 5 lbs. and features machined-in protection grooves for the bridge tubes
• Provides perfectly even thickness and strength throughout the caliper block, eliminating weak spots that can lead to warpage or failure
• Aluminum pistons for superior heat resistance and reduced unsprung weight
• High-temperature seals and stainless-steel brake pad wear plates standard on every caliper
• Opposed piston design greatly improves pad wear and caliper rigidity compared to OEM

Floating Rotor Technology:

• Two-piece floating disc assembly reduces both rotating and unsprung weight
• The floating outer ring is designed to shift slightly as needed, allowing for better self-centering in the caliper — lowering brake drag and improving performance through more even application
• Floating design prevents thermal stresses from extreme heat from warping the disc or cupping the braking surface
• Unique slot pattern expels gas and pad debris faster than conventional designs while significantly reducing braking noise
• Every rotor is heat treated and balanced before shipment for consistent, reliable performance

Brake Lines & Pads:

• D.O.T.-compliant stainless-steel braided brake lines are standard — stops expansion under pressure, delivers quicker pedal response and firmer pedal feel versus stock rubber lines
• Compatible with Ksport SC5 Street Pads (NAOC ceramic compound) or RC1 Race Pads (carbon metallic)
• SC5 Street Pad optimal operating range: 194°F – 1,022°F; reduces brake dust by 50% or more versus race pads

Rotor Style Guide:

• Cross Drilled (CO): Runs cooler, recommended for daily-driven street vehicles
• Slotted: Recommended for vehicles with frequent track use

Additional Features:

• Caliper piston options: 4, 6, or 8 piston configurations available
• CNC machined carbon steel caliper brackets included — allows direct bolt-on to OEM caliper bracket location
• OEM ABS systems remain fully functional with this kit
• Caliper finish options include Orange, Red, Black, and Yellow; premium anodized finishes available
• Titanium center bell and twin-color anodized center bell upgrade options available
• Backed by a 12-month warranty covering manufacturer defects

The Ksport BKSC080-621CO is built to order — designed for drivers who demand proven racetrack engineering on the street or strip, with a bolt-on installation that requires minimal tools and no vehicle modifications in most applications.
