Ksport BKHD310-621SO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper Options

The Ksport BKHD310-621SO is a high-performance floating rotor big brake kit engineered to deliver maximum stopping power with reduced brake fade. Designed with advanced brake technology, this system continuously cools and refreshes the brake pad surface under braking, making it an ideal upgrade for both performance street driving and track use.

Caliper Design:

• Available in 4, 6, or 8 piston caliper configurations to suit your braking needs
• Extreme lightweight one-piece caliper in a differential bore configuration
• CNC machined from aircraft-grade billet aluminum
• Weighs just over 5 lbs. each for reduced unsprung weight
• Machined-in protection grooves for bridge tubes
• Opposed piston design improves pad wear and caliper rigidity over OEM
• Aluminum pistons with high-temperature seals
• Stainless-steel brake pad wear plates included as standard

Rotor Design:

• 2-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design prevents thermal stresses from warping the disc or cupping the braking surface under extreme heat
• Unique slot pattern rapidly expels gas and pad debris while greatly reducing braking noise
• Every rotor is heat treated and balanced prior to shipment for optimal performance

Additional Features:

• Stainless-steel brake lines prevent expansion under pressure for consistent pedal feel
• Designed for straightforward installation with minimal tools required in most applications

Cross-drilled rotors are recommended for daily-driven vehicles due to cooler operating temperatures, while slotted rotors are the preferred choice for vehicles seeing frequent track use. The Ksport BKHD310-621SO big brake kit represents a complete, performance-engineered braking upgrade built to outperform stock systems in both durability and stopping confidence.
