Ksport BKSB150-621CO Floating Brake Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper

The Ksport BKSB150-621CO is a high-performance floating rotor big brake kit engineered to deliver superior stopping power with dramatically reduced brake fade. Available with your choice of 4, 6, or 8 piston caliper configurations, this system is built for drivers who demand both street and track-capable braking performance.

Ksport's 2-piece floating disc assembly is the centerpiece of this kit. The floating design isolates thermal stress caused by extreme heat, preventing rotor warping and braking surface cupping that can occur with conventional one-piece rotors. Every rotor is heat treated and precision balanced before shipment to ensure consistent, fade-free performance from the first stop.

The rotors feature Ksport's unique slot design, which expels gas and pad debris more efficiently than conventional slot patterns while significantly reducing braking noise. The 2-piece construction also reduces both rotating and unsprung weight, contributing to improved handling and steering response.

Key Features:

• Floating 2-piece rotor assembly minimizes thermal stress and prevents disc warping
• Available in 4, 6, or 8 piston opposed caliper configurations
• CNC machined one-piece caliper from aircraft-grade billet aluminum — weighs just over 5 lbs. each
• Differential bore caliper design for optimized pad wear and enhanced caliper rigidity over OEM
• Aluminum pistons with high-temperature seals and stainless-steel brake pad wear plates
• Machined-in protection grooves for bridge tubes
• Stainless-steel brake lines prevent expansion under pressure for consistent pedal feel
• Proprietary slot design expels gas and pad debris faster than conventional designs
• Heat treated and balanced rotors for optimum performance right out of the box
• Designed for straightforward installation with minimal tools required

Ksport big brake kits are engineered to continually cool and refresh the brake pad surface under repeated hard braking, making this kit equally at home on spirited street drives and demanding track sessions. The opposed piston caliper design delivers improved pad contact, more even wear, and greater structural rigidity compared to standard OEM sliding calipers.
