Ksport BKAC032-621CO Floating Rotor Big Brake Kit Piston Caliper Options - 4 6 or 8

The Ksport BKAC032-621CO is a high-performance big brake kit featuring a full-floating two-piece rotor design paired with your choice of 4, 6, or 8 piston caliper configuration. Engineered to dramatically reduce brake fade while continuously cooling and refreshing the brake pad surface under sustained braking, this bolt-on upgrade delivers exceptional stopping power for both street and track applications.

Floating Rotor Design:

• Two-piece disc assembly reduces both rotating and unsprung weight for improved handling response
• Floating outer rotor section shifts slightly as needed for better self-centering in the caliper, lowering brake drag and improving pad application evenness
• Eliminates thermal stress warping and braking surface cupping caused by extreme heat

Caliper Construction:

• CNC machined from a single solid billet of aircraft-grade aluminum — not cast or welded — for perfectly even wall thickness and superior strength
• Lightweight one-piece opposed-piston design weighing just over 5 lbs. each
• Differential bore configuration improves pad wear and caliper rigidity over OEM designs
• Machined-in bridge tube protection grooves for added durability
• Aluminum pistons with high-temperature seals for reliable operation under racetrack conditions
• Stainless-steel brake pad wear plates standard on every caliper

Rotor Technology:

• Available in Cross Drilled or Slotted rotor styles — Cross Drilled rotors run cooler and are recommended for daily-driven vehicles; Slotted rotors are preferred for track use due to superior heat and gas dispersal
• Unique slot geometry reduces braking noise and expels gas and pad debris faster than conventional designs
• Every rotor is heat treated and precision balanced prior to shipment for consistent, optimal performance

Brake Lines:

• D.O.T.-compliant stainless-steel braided brake lines included
• Eliminates line expansion under pressure for quicker, firmer pedal response compared to stock rubber lines

All Ksport Big Brake Kits are designed for straightforward installation requiring minimal tools and no vehicle modifications in most applications, and come backed by a 12-month manufacturer's warranty covering defects. Kits are built to order — please allow 4–6 weeks for production and delivery.
