Ksport BKIN310-443SO Floating Rotor Big Brake Kit 4, 6, or 8 Piston Caliper

The Ksport BKIN310-443SO Big Brake Kit delivers maximum stopping power through advanced brake technology engineered to dramatically reduce brake fade while continuously cooling and refreshing the brake pad surface during hard braking. Designed for straightforward installation with minimal tools required in most applications, this kit represents a significant upgrade over factory braking systems.

Caliper Design & Construction:

• Available in 4, 6, or 8 piston caliper configurations to suit your performance needs
• Extreme lightweight one-piece opposed piston caliper in differential bore configuration
• CNC machined from aircraft-grade billet aluminum for superior strength and reduced weight
• Weighs just over 5 lbs. each for significant unsprung weight savings
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons with high-temperature seals for consistent performance under extreme heat
• Stainless-steel brake pad wear plates included as standard
• Opposed piston design delivers improved pad wear and greater caliper rigidity versus OEM

Rotor Design & Technology:

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

Brake Lines:

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

The Ksport BKIN310-443SO big brake kit is engineered for drivers who demand reliable, fade-free braking performance whether on the street or the track. Every component is purpose-built to outperform OEM systems in both durability and braking response.
