Ksport BKSB200-621SO Floating Brake Rotor Big Brake Kit Piston Caliper - 4 6 or 8

The Ksport BKSB200-621SO is a premium floating brake rotor designed as part of Ksport's big brake kit system, available with 4, 6, or 8 piston caliper configurations to suit a wide range of performance and racing applications. This two-piece disc assembly significantly reduces both rotating and unsprung weight compared to traditional single-piece rotors, contributing to improved handling and response.

The floating disc design is engineered to eliminate thermal stress caused by extreme braking heat, preventing disc warping and cupping of the braking surface — a critical advantage for performance driving and track use. Ksport's unique slot pattern expels gas and pad debris faster than conventional designs while minimizing braking noise for a cleaner, more consistent pedal feel.

Key Features:

• Floating two-piece disc assembly — reduces rotating and unsprung weight for improved dynamics
• Thermal stress management — floating design prevents warping and braking surface degradation under extreme heat
• Unique slot design — rapidly expels gas and brake pad debris, reduces braking noise
• Heat treated and balanced — every rotor is heat treated and balanced prior to shipment for consistent, reliable performance
• Compatible with 4, 6, or 8 piston calipers — flexible caliper options to match your performance requirements
• Reduced brake fade — system design continuously cools and refreshes the brake pad surface under braking

Ksport big brake kits are engineered for easy installation with minimal tools required in most applications. The system pairs with Ksport's CNC-machined aircraft-grade billet aluminum calipers featuring differential bore configuration, aluminum pistons, high-temperature seals, stainless-steel brake pad wear plates, and stainless-steel brake lines that resist expansion under pressure. The opposed piston caliper design delivers superior pad wear and caliper rigidity versus OEM brake systems.

Slotted rotors like this unit are recommended for vehicles that see frequent track use, while cross-drilled rotors are better suited for daily-driven vehicles. For maximum braking performance and fade resistance on the track, the Ksport BKSB200-621SO floating rotor delivers the engineering precision serious drivers demand.
