Ksport BKMT250-621CO Big Brake Kit Floating Rotor Cross Drilled Piston Caliper Options - 4/6/8

The Ksport BKMT250-621CO is a high-performance big brake kit featuring a two-piece floating rotor with cross-drilled disc and your choice of 4, 6, or 8 piston caliper configuration. Engineered to dramatically reduce brake fade while continuously refreshing the pad surface under hard braking, this kit delivers confident, consistent stopping power for both street and track applications.

Floating Rotor Design:

• Two-piece floating disc assembly reduces both rotating and unsprung weight
• Floating outer section shifts slightly as needed for better self-centering in the caliper, lowering brake drag and promoting more even pad application
• Eliminates thermal stress warping and braking surface cupping caused by extreme heat
• Every rotor is heat treated and balanced before shipment for optimal performance
• Cross-drilled rotor style runs cooler than slotted — recommended for daily-driven vehicles
• Unique slot design expels gas and pad debris faster than conventional designs, greatly reducing brake noise

Caliper Construction:

• CNC machined from a single billet of aircraft-grade aluminum — not cast or welded — for perfectly even wall thickness and superior strength
• Differential bore, opposed-piston design improves pad wear and caliper rigidity over OEM
• Aluminum pistons for enhanced heat resistance and consistent operation
• High-temperature seals and stainless-steel brake pad wear plates standard on every caliper
• Machined-in protection grooves for bridge tube durability
• Caliper weighs just over 5 lbs. each for significant unsprung weight reduction

Brake Lines & Hardware:

• D.O.T.-compliant stainless-steel braided brake lines included standard
• Stainless lines eliminate hose expansion under pressure for quicker pedal response and firmer feel vs. stock rubber lines
• CNC machined carbon steel caliper brackets included

Brake Pads:

• NAOC Ceramic pads included — optimal for street and occasional track use
• Operating temperature range: 194°F – 1,022°F for fast warm-up under normal driving conditions
• Reduces brake dust by 50% or more compared to race pads

All Ksport big brake kits are backed by a 12-month warranty covering manufacturer defects. Kits are built to order.
