Ksport BKMZ060-621CO Floating Rotor Big Brake Kit Piston Caliper Options - 4/6/8

The Ksport BKMZ060-621CO is a high-performance floating rotor big brake kit designed to deliver a significant upgrade in stopping power over OEM brake systems. Available with 4, 6, or 8 piston caliper configurations, this kit is engineered to reduce brake fade, manage heat effectively, and continuously refresh the brake pad surface during repeated braking events.

Two-Piece Floating Rotor Design:

The two-piece floating disc assembly reduces both rotating and unsprung weight compared to conventional solid rotors. The floating outer ring is designed to shift slightly under load, allowing for better self-centering in the caliper, which lowers brake drag and promotes more even pad application. This design also isolates thermal stresses from extreme heat, helping prevent rotor warping or cupping of the braking surface. Every rotor is heat treated and precision balanced prior to shipment. Cross drilled rotors are recommended for daily-driven applications due to their cooler running temperatures, while slotted rotors are better suited for vehicles that see frequent track use.

CNC-Machined Billet Aluminum Calipers:

• One-piece construction CNC machined from aircraft-grade billet aluminum
• Differential bore opposed piston configuration for improved pad wear and caliper rigidity over OEM
• Weighs just over 5 lbs. each for significant unsprung weight reduction
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons for superior heat resistance
• High-temperature seals and stainless-steel brake pad wear plates standard

Rotor Features:

• Two-piece disc assembly reduces rotating and unsprung weight — rotors can weigh up to 50% less than OEM equivalents of the same size
• Unique slot design expels gas and pad debris faster than conventional slot patterns
• Heat treated and balanced before shipment for consistent, reliable performance
• Available in cross drilled or slotted finish
• Optional Titanium Center Bell and Hardware or Twin Color Anodized Center Bell upgrades available

Brake Lines & Pads:

• D.O.T.-compliant stainless-steel braided brake lines included — stop expansion under pressure for a firmer, more responsive pedal feel
• NAOC Ceramic brake pads provide optimal performance between 194°F and 1,022°F
• Ceramic pads reduce brake dust by 50% or more compared to race pads

The Ksport BKMZ060-621CO big brake kit is designed for straightforward bolt-on installation with minimal tools required and no vehicle modifications needed in most applications. All OEM ABS systems remain fully functional with this kit. Backed by Ksport's 12-month manufacturer defect warranty.
