Ksport BKHD190-621CO Floating Rotor Big Brake Kit Piston Caliper Options - 4/6/8

The Ksport BKHD190-621CO is a high-performance big brake kit featuring a full-floating two-piece rotor design and your choice of 4, 6, or 8 piston caliper configurations. Engineered to deliver significantly enhanced stopping power over stock brake systems, this kit dramatically reduces brake fade and continuously cleans and refreshes the brake pad surface under heavy braking conditions — making it an ideal upgrade for both spirited street driving and track use.

Floating Rotor Design:

• Full-floating two-piece disc assembly reduces both rotating and unsprung weight
• Floating outer rotor section self-centers in the caliper, lowering brake drag and improving pad application consistency
• Floating design eliminates thermal stress warping and prevents cupping of the braking surface under extreme heat
• Every rotor is heat treated and precision balanced prior to shipment for optimal performance
• Unique slot design expels gas and pad debris faster than conventional slot designs, reducing braking noise
• Rotors can weigh up to 50% less than OEM rotors of comparable size

Caliper Construction:

• CNC machined from a single billet of aerospace-grade aluminum — no casting or welding — for perfectly uniform wall thickness and maximum strength
• Opposed piston, differential bore configuration improves pad wear evenness and caliper rigidity over OEM designs
• Each caliper weighs approximately 5 lbs., saving significant weight over stock units
• Machined-in bridge tube protection grooves for added structural integrity
• Aluminum pistons with high-temperature seals for consistent operation at racetrack temperatures
• Stainless-steel brake pad wear plates standard on every caliper

Brake Lines & Pads:

• D.O.T.-compliant stainless-steel braided brake lines included standard — resist expansion under pressure for a firmer, more responsive pedal feel
• NAOC Ceramic brake pads deliver optimal performance from street to occasional track use
• Ceramic pads produce 50% less brake dust than race pads and minimize rotor wear
• Optimal pad operating temperature range: 194°F – 1,022°F

Rotor Style Options:

• Cross Drilled: Runs cooler, recommended for daily-driven vehicles
• Slotted: Superior heat and gas evacuation, recommended for frequent track use

Additional Details:

• Available with 4, 6, or 8 piston caliper configurations to match your performance requirements
• Optional upgrade to Titanium Center Bell and Hardware or Twin Color Anodized Center Bell available
• Calipers available in standard painted finishes (Orange, Red, Black, Yellow) or premium anodized/polished upgrades
• OEM ABS systems remain fully functional with this brake kit
• Bolt-on installation — no vehicle modifications required in most applications
• Backed by a 12-month manufacturer defect warranty
• Built to order — allow 4–6 weeks for production and delivery

Whether building a dedicated track car or upgrading a high-performance street vehicle, the Ksport BKHD190-621CO big brake kit delivers race-proven stopping performance with precise, fade-resistant braking at every corner entry.
