Ksport BKVO030-621SO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper Options

The Ksport BKVO030-621SO is a high-performance floating rotor big brake kit engineered to deliver superior stopping power and dramatically reduced brake fade. Available with 4, 6, or 8 piston caliper configurations, this system is built for drivers who demand consistent, fade-resistant braking under both street and track conditions.

Caliper Design & Construction:

• Extreme lightweight one-piece caliper in a differential bore configuration
• CNC machined from aircraft-grade billet aluminum
• Weighs just over 5 lbs. each for significant unsprung weight reduction
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons with high-temperature seals for reliable performance under extreme heat
• Stainless-steel brake pad wear plates standard on every caliper
• Opposed piston caliper design improves pad wear evenness and caliper rigidity over OEM

Rotor Design & Technology:

• 2-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design prevents thermal warping and braking surface cupping caused by extreme heat stress
• Unique slot design rapidly expels gas and pad debris while minimizing braking noise
• Every rotor is heat treated and dynamically balanced before shipment for optimal performance consistency
• Cross-drilled rotors available for cooler operation — ideal for daily-driven applications
• Slotted rotor option recommended for track or performance-focused use

Brake Lines & System Integration:

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

Ksport big brake kits integrate modern brake technology to continuously cool and refresh brake pad surfaces during hard braking events, making the BKVO030-621SO an excellent upgrade for performance street use, autocross, and track days.
