Ksport BKMD400-621CO Floating Brake Rotor Big Brake Kit or Piston Caliper Options - with 4 6 8

The Ksport BKMD400-621CO is a high-performance floating brake rotor designed as part of Ksport's big brake kit lineup, delivering exceptional stopping power with advanced thermal management and reduced brake fade. Available with 4, 6, or 8 piston caliper options, this system is engineered for both street and track applications.

Rotor Design & Construction:

• Two-piece floating disc assembly reduces overall rotating and unsprung weight for improved handling response
• Floating disc design absorbs and dissipates thermal stresses from extreme heat, preventing disc warping and braking surface cupping
• Unique slot pattern rapidly expels gas and pad debris while minimizing braking noise
• Every rotor is heat treated and balanced prior to shipment for consistent, reliable performance
• Cross-drilled rotors run cooler and are recommended for daily-driven vehicles; slotted rotors are optimized for track or performance-focused use

Caliper Features:

• Lightweight one-piece CNC-machined billet aluminum caliper crafted from aircraft-quality billet — weighs just over 5 lbs. each
• Differential bore configuration for optimized clamping force distribution
• Opposed piston design improves pad wear evenness and caliper rigidity over OEM calipers
• Machined-in protection grooves for bridge tubes
• Aluminum pistons with high-temperature seals for fade resistance under repeated hard braking
• Stainless steel brake pad wear plates standard on every caliper

Brake Lines & Hardware:

• Stainless steel braided brake lines prevent hose expansion under high pressure for a firm, consistent pedal feel
• Designed for straightforward installation with minimal tools required in most applications

The Ksport BKMD400-621CO big brake kit floating rotor is an ideal upgrade for enthusiasts seeking maximum braking performance, reduced brake fade, and improved thermal cooling during spirited driving or track days.
