Ksport BKHD140-621SO Floating Rotor Big Brake Kit | 4, 6, or 8 Piston Caliper

The Ksport BKHD140-621SO is a premium floating rotor big brake kit engineered to deliver maximum stopping power with significantly reduced brake fade. Designed for enthusiasts who demand consistent, high-performance braking under both daily driving and track conditions, this kit integrates modern brake technology into a complete, easy-to-install system requiring minimal tools in most applications.

Caliper Design:

• Available in 4, 6, or 8 piston caliper configurations to match your braking demands
• Extreme lightweight, one-piece caliper machined in a differential bore configuration
• CNC machined from aircraft-quality billet aluminum, weighing just over 5 lbs. each
• Machined-in protection grooves for bridge tube durability
• Opposed piston design improves pad wear consistency and caliper rigidity over OEM
• Aluminum pistons with high-temperature seals for performance reliability
• Stainless-steel brake pad wear plates included on every caliper

Rotor Design:

• Floating 2-piece disc assembly reduces both rotating and unsprung weight
• Floating disc design prevents thermal stress from warping the rotor or cupping the braking surface under extreme heat
• Unique slot pattern expels gas and pad debris faster than conventional slot designs while minimizing braking noise
• Every rotor is heat treated and balanced prior to shipment for optimal performance
• Cross-drilled rotors run cooler and are ideal for daily-driven vehicles
• Slotted rotors are recommended for vehicles with higher track use

Brake Lines:

• Stainless-steel braided brake lines resist expansion under pressure for consistent, firm pedal feel

The Ksport BKHD140-621SO big brake kit continuously cools and refreshes the brake pad surface during braking, keeping performance consistent lap after lap. Whether upgrading for spirited street driving or aggressive track sessions, this system delivers the stopping confidence that serious drivers require.
