Ksport BKMZ170-621CO Floating Brake Rotor Big Brake Kit Piston Caliper - 4/6/8

The Ksport BKMZ170-621CO is a high-performance floating brake rotor designed as part of Ksport's big brake kit system, available with 4, 6, or 8 piston caliper options to match your specific performance braking demands. This 2-piece disc assembly significantly reduces both rotating and unsprung weight while delivering superior stopping power over OEM brake setups.

Floating Rotor Design:

• 2-piece floating disc assembly isolates thermal stresses from extreme heat, preventing disc warping and braking surface cupping
• Unique slot design reduces braking noise and expels gas and pad debris more efficiently than conventional slot patterns
• Every rotor is heat treated and balanced before shipment for consistent, reliable performance
• Reduces both rotating and unsprung weight compared to traditional single-piece rotor designs

Caliper Features (Kit Options):

• Available in 4, 6, or 8 piston configurations — select the caliper that matches your braking application
• CNC machined from aircraft-grade billet aluminum in a differential bore, one-piece design
• Lightweight construction at just over 5 lbs. per caliper with machined-in bridge tube protection grooves
• Opposed piston caliper design improves pad wear and caliper rigidity over OEM calipers
• Equipped with aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates
• Stainless-steel braided brake lines resist expansion under pressure for consistent pedal feel

Performance Benefits:

• Dramatically reduces brake fade under sustained or repeated hard braking
• Continuously cools and refreshes the brake pad contact surface during braking
• Designed for easy installation with minimal tools required in most applications
• Slotted rotor design is ideal for track and performance driving applications

The Ksport BKMZ170-621CO floating rotor delivers the engineering precision and thermal management demanded by performance and track-day drivers. Whether paired with the 4, 6, or 8 piston caliper option, this system provides a substantial upgrade in braking confidence, consistency, and control over factory brake components.
