Ksport BKVW081-621CO Big Brake Kit Floating Rotor 4, 6, or 8 Piston Caliper

The Ksport BKVW081-621CO Big Brake Kit delivers a significant upgrade in stopping performance over stock braking systems. Engineered to dramatically reduce brake fade, this kit continuously cools and refreshes the brake pad surface under heavy braking conditions — making it equally capable on the street or the track.

Lightweight Billet Aluminum Calipers:

• CNC machined from aircraft-grade billet aluminum in a one-piece construction — no casting, no welding
• Differential bore configuration for optimized pad pressure and wear
• Each caliper weighs just over 5 lbs, offering substantial unsprung weight savings over OEM
• Machined-in protection grooves for bridge tubes add structural integrity
• Available in 4, 6, or 8 piston configurations to suit your braking requirements
• Opposed piston design greatly improves pad wear evenness and caliper rigidity vs. stock

Floating Two-Piece Rotor Design:

• Two-piece disc assembly reduces both rotating and unsprung weight
• Floating outer rotor section shifts slightly as needed for better self-centering in the caliper, lowering brake drag and improving pad application evenness
• Floating disc design prevents thermal stresses from warping the disc or cupping the braking surface under extreme heat
• Unique slot pattern expels gas and pad debris faster than conventional slot designs while reducing braking noise
• Every rotor is heat treated and balanced prior to shipment for consistent, reliable performance
• Available in Cross Drilled or Slotted rotor styles — cross drilled recommended for daily street use; slotted recommended for track-focused applications

Premium Supporting Components:

• Aluminum pistons with high-temperature seals for superior heat resistance
• Stainless steel brake pad wear plates standard on every caliper
• D.O.T.-compliant stainless steel braided brake lines eliminate expansion under pressure, delivering a firmer pedal feel and quicker response than stock rubber lines

Easy Bolt-On Installation:

• Designed for bolt-on fitment with minimal tools required in most applications
• No vehicle modifications needed in most installations
• All OEM ABS systems remain fully functional with this brake system

Ksport big brake kits are built to order and backed by a 12-month manufacturer's warranty covering defects in materials and workmanship.
