Ksport BKMZ120-621CO Floating Brake Rotor Big Brake Kit or Piston Caliper Options - with 4 6 8

The Ksport BKMZ120-621CO is a high-performance floating rotor big brake kit engineered to deliver maximum stopping power with significantly reduced brake fade. Designed for enthusiasts who demand both street and track capability, this system integrates advanced brake technology to continuously cool and refresh the brake pad surface during hard braking events.

Caliper Design & Construction:

• Available in 4, 6, or 8 piston caliper configurations to match your performance requirements
• Extreme lightweight one-piece opposed piston caliper in a differential bore configuration
• CNC machined from aircraft-quality billet aluminum, weighing just over 5 lbs. each
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons with high-temperature seals for reliable performance under extreme heat
• Stainless-steel brake pad wear plates standard on every caliper
• Opposed piston design improves pad wear evenness and caliper rigidity over OEM calipers
• Stainless-steel brake lines prevent expansion under pressure for consistent pedal feel

Floating Rotor Technology:

• 2-piece floating disc assembly reduces both rotating and unsprung weight
• Floating disc design eliminates thermal stress from extreme heat, preventing rotor warp and braking surface cupping
• Unique slot pattern rapidly expels gas and pad debris while minimizing braking noise
• Every rotor is heat treated and precision balanced before shipment for consistent, reliable performance

Rotor Style Options:

• Cross-drilled rotors — run cooler under normal conditions; recommended for daily-driven vehicles
• Slotted rotors — optimized for high-frequency braking; recommended for track or performance-focused use

Engineered for straightforward installation with minimal tooling required in most applications, the Ksport BKMZ120-621CO big brake kit is a complete upgrade solution combining lightweight construction, thermal management, and consistent braking performance for both street and competition environments.
