Ksport BKAC030-621CO Floating Rotor Big Brake Kit | 4, 6, or 8 Piston Caliper

The Ksport BKAC030-621CO is a premium floating rotor big brake kit engineered to deliver maximum stopping power with significantly reduced brake fade. Available with 4, 6, or 8 piston caliper options, this system is built for drivers who demand race-proven braking performance without sacrificing streetability. Designed for straightforward installation with minimal tooling required in most applications.

Caliper Design:

• Extreme lightweight one-piece caliper in a differential bore configuration
• CNC machined from aircraft-quality billet aluminum
• Weighs just over 5 lbs. each for significant unsprung weight reduction
• Machined-in bridge tube protection grooves for added durability
• Opposed piston design improves pad wear consistency and caliper rigidity over OEM
• Aluminum pistons with high-temperature seals for reliable performance under extreme heat
• Stainless steel brake pad wear plates included as standard

Rotor & Disc Assembly:

• 2-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design isolates thermal stress, preventing warping and braking surface cupping under extreme heat
• Unique slot design expels gas and pad debris faster than conventional slot patterns, reducing braking noise
• Every rotor is heat treated and balanced prior to shipment for optimal performance and longevity

Brake Lines:

• Stainless steel braided brake lines prevent hose expansion under pressure for a firm, consistent pedal feel

Rotor Style Guide:

• Cross-drilled rotors run cooler and are recommended for daily-driven street vehicles
• Slotted rotors are recommended for vehicles with frequent track or performance use

The Ksport BKAC030-621CO big brake kit continuously cools and refreshes the brake pad surface during braking, making it an ideal upgrade for performance enthusiasts seeking a direct replacement that outperforms OEM braking systems in both power and endurance.
