Ksport BKIN420-653SO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper Options

The Ksport BKIN420-653SO Big Brake Kit delivers maximum stopping power with advanced brake technology engineered to reduce brake fade, continuously cool brake pads, and maintain consistent performance under heavy braking conditions. Designed for straightforward installation with minimal tools required in most applications, this kit is an ideal upgrade over factory braking systems.

Caliper Features:

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

Rotor Features:

• 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
• Unique slot design expels gas and pad debris faster than conventional slot designs, greatly reducing brake noise
• Every rotor is heat treated and 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 firm, consistent pedal feel

The Ksport BKIN420-653SO big brake kit is built for drivers who demand superior braking performance, whether on the street or the track. The combination of lightweight billet calipers, a precision-engineered floating rotor, and high-temperature components ensures reliable, fade-resistant stopping power in the most demanding conditions.
