Ksport BKSB210-621CO Floating Brake Rotor Big Brake Kit or Piston Caliper Options - with 4 6 8

The Ksport BKSB210-621CO floating rotor big brake kit delivers serious stopping power through advanced brake technology engineered to reduce brake fade and maintain consistent pad performance under repeated hard braking. Available with 4, 6, or 8 piston caliper options, this system is designed for straightforward installation with minimal tools required in most applications.

Caliper Design & Construction:

• Extreme lightweight one-piece CNC machined caliper crafted from aircraft-quality billet aluminum
• Differential bore configuration for optimized pad contact and pressure distribution
• Weighs just over 5 lbs. each for reduced unsprung weight
• Machined-in protection grooves for bridge tube durability
• Opposed piston design improves pad wear evenness and caliper rigidity over OEM
• Aluminum pistons with high-temperature seals for consistent performance at elevated temperatures
• Stainless-steel brake pad wear plates standard on every caliper
• Stainless-steel braided brake lines resist expansion under pressure for a firm, responsive pedal feel

Rotor Design & Technology:

• 2-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design isolates thermal stress, preventing warping and braking surface cupping under extreme heat
• Unique slot geometry rapidly expels gas and pad debris while significantly reducing braking noise
• Every rotor is heat treated and balanced prior to shipment for optimum performance consistency
• Cross-drilled rotors provide cooler running temperatures — ideal for daily-driven vehicles
• Slotted rotors are recommended for track-focused or high-performance driving applications

The Ksport big brake system is a complete, performance-engineered upgrade over factory braking components, combining lightweight materials, precision machining, and proven thermal management to deliver confident, fade-resistant braking in both street and track environments.
