Ksport BKBM340-621CO Big Brake Kit Front 6-Piston Cross Drilled Floating Rotor Procomp

The Ksport BKBM340-621CO Procomp Big Brake Kit delivers a significant upgrade in stopping power through a sophisticated bolt-on design that requires no permanent vehicle modifications. Engineered to dramatically reduce brake fade, this system continuously cools and refreshes the brake pad surface under heavy braking conditions, making it well suited for both spirited street driving and occasional track use.

Caliper Construction:

• One-piece billet construction — each caliper is CNC machined from a single block of aircraft-grade 6061-T6 aluminum, eliminating weak points caused by casting or welding
• Differential bore configuration with opposed pistons for improved pad wear and superior caliper rigidity over OEM designs
• Aluminum pistons provide enhanced heat resistance for uncompromised operation under sustained braking
• High-temperature seals and stainless-steel brake pad wear plates included as standard
• Machined-in protection grooves for the bridge tubes
• Available in 4, 6, or 8 piston configurations to suit your performance requirements

Two-Piece Floating Rotor:

• Full-floating 2-piece disc assembly reduces both rotating and unsprung weight
• The floating outer ring shifts slightly as needed for better self-centering in the caliper, reducing brake drag and promoting more even pad application
• Floating design prevents thermal stresses from warping the disc or cupping the braking surface under extreme heat
• Every rotor is heat treated and balanced prior to shipment for optimal, vibration-free performance
• Unique slot pattern expels gas and pad debris faster than conventional designs while significantly reducing braking noise
• Cross-drilled rotor style runs cooler and is recommended for daily-driven vehicles; slotted rotors are available for track-focused applications
• Two-piece rotors commonly weigh up to 50% less than OEM rotors of comparable size

Brake Lines & Hardware:

• D.O.T.-compliant stainless-steel braided brake lines prevent hose expansion under pressure
• Firmer pedal feel and quicker pedal response compared to stock rubber brake lines
• CNC machined carbon steel caliper brackets allow direct bolt-up to OEM caliper mounting locations

Included Brake Pads:

• NAOC SC5 Ceramic Street Pads included as standard — optimal operating range of 194°F – 1,022°F for fast warm-up under normal driving conditions
• Reduces brake dust by 50% or more compared to race compound pads
• Coefficient of friction between 0.46 and 0.53

Warranty & Compatibility:

• Backed by a 12-month limited warranty covering manufacturer defects
• All OEM ABS systems remain fully functional with this brake kit installed
• Designed for 2WD applications; minimal tools required for installation in most applications
• Caliper finish options available including painted colors (Orange, Red, Black, Yellow), high-polish, anodized, and Titanium center bell upgrades
