Ksport BKVW081-621SO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper Options

The Ksport BKVW081-621SO is a premium big brake kit engineered to deliver the ultimate in stopping power. Combining advanced brake technology with precision manufacturing, this system dramatically reduces brake fade while continuously cooling and refreshing the brake pad surface during heavy braking. Designed for straightforward installation with minimal tooling required in most applications, this kit is an ideal upgrade for both street performance and track use.

Lightweight One-Piece Caliper Design:

• Available in 4, 6, or 8 piston caliper configurations to suit your performance needs
• CNC machined from aircraft-quality billet aluminum in a differential bore configuration
• Weighs just over 5 lbs. each for reduced unsprung weight
• Machined-in protection grooves for bridge tube security
• Aluminum pistons for lightweight, corrosion-resistant performance
• High-temperature seals rated for extreme braking conditions
• Stainless-steel brake pad wear plates standard on every caliper
• Opposed piston caliper design improves pad wear evenness and caliper rigidity over OEM designs

2-Piece Floating Rotor Assembly:

• 2-piece disc construction reduces both rotating and unsprung weight
• Floating disc design isolates thermal stress, preventing warping and braking surface cupping under extreme heat
• Unique slot pattern rapidly expels gas and pad debris while minimizing braking noise
• Every rotor is heat treated and dynamically balanced before shipment for consistent, reliable performance
• Stainless-steel braided brake lines eliminate 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 — recommended for vehicles with frequent track or performance driving use

The Ksport big brake kit with the BKVW081-621SO floating rotor is a complete, high-performance braking solution built to outperform factory brake systems in both durability and stopping capability. Whether upgrading for aggressive street driving or competitive track events, this kit delivers the confidence of race-proven braking technology.
