Ksport BKNS190-621CO Floating Brake Rotor Big Brake Kit

The Ksport BKNS190-621CO is a high-performance floating brake rotor designed as part of Ksport's big brake kit system, compatible with 4, 6, or 8 piston caliper configurations. Engineered for drivers who demand serious stopping power, this system dramatically reduces brake fade and continuously cools and refreshes the brake pad surface during hard braking events.

Rotor Design & Construction:

• Two-piece floating disc assembly reduces both rotating and unsprung weight for improved handling response
• Floating disc design eliminates thermal stress transfer, preventing rotor warping and braking surface cupping under extreme heat
• Unique slot design expels gas and pad debris faster than conventional slot patterns, significantly reducing braking noise
• Every rotor is heat treated and balanced prior to shipment for consistent, reliable performance

Caliper Features (when paired with Ksport caliper):

• Available in 4, 6, or 8 piston opposed piston configurations to match your performance needs
• Lightweight, one-piece caliper CNC machined from aircraft-grade billet aluminum — weighs just over 5 lbs. each
• Differential bore configuration for optimized pad wear and braking force distribution
• 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 caliper design improves pad wear evenness and caliper rigidity over OEM designs
• Stainless-steel brake lines resist expansion under pressure for firm, consistent pedal feel

Installation:

• Designed for straightforward installation with minimal tools required in most applications

Application Notes:

• Cross-drilled rotors run cooler and are recommended for daily-driven vehicles
• Slotted rotors are recommended for vehicles with frequent track use

Ksport big brake kits deliver the ultimate in braking performance for enthusiasts and track drivers alike. The combination of aerospace-grade materials, precision CNC machining, and advanced thermal management design make these kits a benchmark upgrade over OEM braking systems.
