Ksport BKBM340-621SO Floating Brake Rotor Big Brake Kit Piston Caliper - 4 6 or 8

The Ksport BKBM340-621SO is a high-performance floating rotor big brake kit engineered to deliver maximum stopping power with significantly reduced brake fade. Available with 4, 6, or 8 piston caliper options, this system is designed for enthusiasts who demand precision braking on both the street and the track.

Two-Piece Floating Disc Assembly:

Ksport's two-piece floating disc design reduces both rotating and unsprung weight while allowing the rotor to float freely, relieving thermal stress caused by extreme heat. This prevents warping and cupping of the braking surface — a common issue with conventional one-piece rotors under aggressive use.

Key Features:

• Floating rotor construction eliminates thermal distortion and rotor warp under extreme braking heat
• Unique slot design rapidly expels gas and pad debris, reducing braking noise more effectively than conventional slot patterns
• Every rotor is heat treated and balanced prior to shipment for consistent, reliable performance
• Two-piece disc assembly minimizes rotating and unsprung weight for improved handling dynamics
• Compatible with 4, 6, or 8 piston caliper configurations for flexible performance tuning

Caliper Specifications:

• CNC machined from aircraft-grade billet aluminum in a differential bore configuration
• Extreme lightweight one-piece design weighing just over 5 lbs. each
• Machined-in protection grooves for bridge tube security
• Aluminum pistons with high-temperature seals for fade resistance
• Stainless steel brake pad wear plates included as standard
• Opposed piston design improves pad wear evenness and caliper rigidity over OEM
• Stainless steel brake lines prevent line expansion under pressure for a firm, consistent pedal feel

Rotor Style Guidance:

• Cross-drilled rotors run cooler and are recommended for daily-driven vehicles
• Slotted rotors are recommended for track-focused applications with heavier braking demands

Designed for straightforward installation with minimal tools required, the Ksport BKBM340-621SO big brake kit is a complete upgrade solution for drivers seeking measurably enhanced braking performance over stock components.
