Ksport BKFD250-621SO ProComp Big Brake Kit Floating Rotor Slotted Piston - 12in Front 6

The Ksport BKFD250-621SO Procomp Big Brake Kit is a sophisticated bolt-on brake upgrade engineered to deliver significantly enhanced stopping power under sustained high-heat conditions. By integrating advanced brake technology, this kit dramatically reduces brake fade while continuously cooling and refreshing the brake pad surface during braking — ideal for both spirited street driving and track use.

Aircraft-Grade Billet Caliper Construction:

• One-piece caliper CNC machined from a solid billet of aircraft-grade aluminum — not cast or welded — for uniform strength and corrosion resistance
• Differential bore configuration for optimized pad clamping force
• Weighs just over 5 lbs. each, saving significant unsprung weight versus OEM calipers
• Machined-in protection grooves for bridge tubes
• Opposed piston design greatly improves pad wear and caliper rigidity over stock

Caliper Components:

• Aluminum pistons for superior heat resistance and consistent operation
• High-temperature seals rated for extreme braking conditions
• Stainless-steel brake pad wear plates standard on every caliper

Two-Piece Floating Rotor Design:

• 12-inch (304mm) slotted rotor with two-piece floating disc assembly
• Reduces both rotating and unsprung weight — rotors can weigh up to 50% less than OEM equivalents
• Floating outer disc shifts slightly as needed for better self-centering in the caliper, lowering brake drag and improving application consistency
• Eliminates thermal stress warping and braking surface cupping caused by extreme heat
• Prevents vibration at higher speeds
• Unique slot design expels gas and pad debris faster than conventional designs while reducing braking noise
• Every rotor is heat treated and balanced before shipment

Brake Lines & Hardware:

• D.O.T.-compliant stainless-steel braided brake lines prevent expansion under pressure
• Firmer pedal feel and quicker response compared to stock rubber lines

Brake Pads:

• NAOC Ceramic pads included for optimal street and occasional track performance
• Reduces brake dust by 50% or more versus race pads
• Operating temperature range: 194°F – 1,022°F

Kit Includes: Calipers, floating brake disc, brake pads, stainless-steel brake lines, and all required installation hardware.

The Ksport Procomp Big Brake Kit is designed for straightforward bolt-on installation with minimal tools required and no vehicle modifications needed in most applications. All Ksport Big Brake Kits are backed by a 12-month warranty covering manufacturer defects. OEM ABS systems remain fully functional with this brake upgrade.
