Ksport BKHD141-621SO Floating Rotor Big Brake Kit with 4, 6, or 8 Piston Caliper

The Ksport BKHD141-621SO is a high-performance big brake kit featuring a two-piece floating rotor assembly and your choice of 4, 6, or 8 piston caliper configurations. Engineered to deliver maximum stopping power while dramatically reducing brake fade, this system is built for drivers who demand consistent, repeatable braking performance under extreme conditions.

Floating Rotor Design:

• Two-piece floating disc assembly reduces both rotating and unsprung weight for improved handling dynamics
• Floating disc interface isolates thermal stresses, preventing rotor warp and braking surface cupping under extreme heat
• Every rotor is heat treated and precision balanced before shipment for optimal performance
• Proprietary slot design expels gas and pad debris faster than conventional patterns while minimizing braking noise

Caliper Features:

• Available in 4, 6, or 8 piston opposed-piston configurations for application-specific performance tuning
• Lightweight one-piece caliper CNC machined from aircraft-quality billet aluminum, weighing just over 5 lbs. each
• Differential bore configuration for optimized pad contact and even wear across the pad surface
• Machined-in bridge tube protection grooves for added structural integrity
• Aluminum pistons reduce unsprung weight while maintaining thermal efficiency
• High-temperature seals and stainless-steel brake pad wear plates included as standard
• Opposed piston design improves pad wear consistency and caliper rigidity over OEM designs

Brake Lines & Hardware:

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

Rotor Type Guidance:

• Cross-drilled rotors run cooler and are recommended for daily-driven street vehicles
• Slotted rotors are recommended for vehicles with heavier track or performance use

The Ksport BKHD141-621SO big brake kit is a complete, race-inspired braking upgrade that continuously refreshes the brake pad surface during braking, keeping pads cool and effective lap after lap or stop after stop.
