Ksport BKHD160-621CO Big Brake Kit Floating Rotor with 4, 6, or 8 Piston Caliper Options

The Ksport BKHD160-621CO Big Brake Kit delivers a significant upgrade in stopping power over factory brake systems, featuring a full-floating two-piece rotor design with your choice of 4, 6, or 8 piston caliper configurations. Engineered to dramatically reduce brake fade while continuously cooling and refreshing the brake pad surface under repeated heavy braking, this kit is equally at home on the street or the track.

Floating Rotor Design:

The two-piece floating disc assembly reduces both rotating and unsprung weight compared to conventional single-piece rotors. The outer rotor section is designed to shift slightly as needed, allowing for better self-centering in the caliper. This lowers brake drag, promotes more even pad application, and prevents thermal stresses from warping the disc or cupping the braking surface under extreme heat.

Billet Aluminum Caliper Construction:

Calipers are CNC machined from a single solid billet of aircraft-grade aluminum — not cast or welded — providing perfectly uniform wall thickness and strength throughout. This one-piece construction eliminates weak spots that can lead to fracturing or warpage over time. Each caliper weighs just over 5 lbs., features a differential bore configuration, machined-in protection grooves for the bridge tubes, and an opposed piston layout for improved pad wear and superior caliper rigidity versus OEM designs.

Key Features:

• Full-floating two-piece rotor assembly reduces rotating and unsprung weight
• Available in 4, 6, or 8 piston caliper configurations
• CNC machined one-piece aircraft-grade billet aluminum calipers (~5 lbs. each)
• Aluminum pistons with high-temperature seals for sustained performance under heat
• Stainless steel brake pad wear plates standard on every caliper
• D.O.T.-compliant stainless steel braided brake lines resist expansion under pressure for a firmer, more responsive pedal feel
• Unique slot design expels gas and pad debris faster than conventional slot patterns, reducing braking noise
• Every rotor is heat treated and balanced before shipment
• Bolt-on installation requiring minimal tools in most applications
• OEM ABS systems remain fully functional

Rotor Style Guidance:

Cross drilled rotors run cooler and are the preferred choice for daily driven vehicles. Slotted rotors offer superior heat and gas dispersal, making them the recommended option for track-focused use or vehicles that see frequent hard braking events.
