Ksport BKFD050-621SO Floating Rotor Big Brake Kit – 4, 6, or 8 Piston Caliper

The Ksport BKFD050-621SO is a high-performance floating rotor big brake kit engineered to deliver maximum stopping power with reduced brake fade and improved thermal management. Designed for enthusiasts who demand more from their braking system, this kit is compatible with 4, 6, or 8 piston caliper configurations to suit a range of performance applications.

Floating Rotor Design:

• 2-piece floating disc assembly reduces both rotating and unsprung weight for improved handling dynamics
• Floating disc design isolates thermal stresses, preventing disc warping and braking surface cupping under extreme heat
• Unique slot pattern expels gas and pad debris faster than conventional slot designs, reducing braking noise
• Every rotor is heat treated and balanced prior to shipment for consistent, reliable performance

Caliper Features:

• Extreme lightweight one-piece CNC-machined caliper crafted from aircraft-grade billet aluminum
• Differential bore configuration for optimized pad contact and even wear
• Weighs just over 5 lbs. each for significant unsprung weight savings
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates included as standard
• Opposed piston design improves pad wear consistency and caliper rigidity over OEM designs

System Highlights:

• Stainless-steel braided brake lines prevent expansion under pressure for a firm, consistent pedal feel
• Engineered for easy installation with minimal tools required in most applications
• Continuously cools and refreshes the brake pad surface during braking to combat fade
• Cross-drilled rotor option recommended for daily-driven vehicles; slotted option recommended for track-focused use

The Ksport BKFD050-621SO big brake kit is a complete braking upgrade solution built with competition-grade materials and precision engineering, delivering the stopping confidence needed for both street and performance driving environments.
