Ksport BKHD050-862SO SuperComp Rear 8-Piston Big Brake Kit with 15.7" 2-Piece Floating Slotted Rotors

The Ksport BKHD050-862SO SuperComp Big Brake Kit is Ksport's most extreme rear brake upgrade, delivering maximum stopping power through an 8-piston caliper design and oversized 15.7-inch (400mm) 2-piece floating slotted rotors. Engineered as a true bolt-on upgrade, this kit installs with minimal tools and requires no vehicle modifications in most applications.

SuperComp Caliper Technology:

• 8-piston opposed caliper design machined from a single billet of aircraft-grade aluminum — no casting, no welding
• One-piece caliper construction ensures uniform wall thickness, eliminating weak spots that can cause fracturing, warpage, or failure under stress
• Aluminum pistons provide superior heat resistance and uncompromised operation at racetrack temperatures
• High-temperature seals and stainless steel brake pad wear plates standard on every caliper
• Opposed piston design greatly improves pad wear and caliper rigidity over OEM designs
• Weighs just over 7 lbs. each — significantly lighter than comparable cast iron units

2-Piece Floating Rotor Assembly:

• 15.7-inch (400mm) slotted rotor paired with a floating disc assembly that reduces both rotating and unsprung weight
• Floating disc design prevents thermal stress from extreme heat warping the disc or cupping the braking surface
• Rotors can weigh up to 50% less than OEM rotors of the same diameter
• Unique slot pattern rapidly expels gas and pad debris, reducing braking noise versus conventional slot designs
• Every rotor is heat treated and balanced before shipment for consistent, reliable performance
• Optional Titanium Center Bell or Twin Color Anodized Center Bell available for further customization

Complete Kit Includes:

• 8-piston SuperComp aluminum calipers (standard painted finish: Orange, Red, Black, or Yellow)
• 2-piece floating slotted brake rotors
• NAOC Ceramic SC5 Street brake pads — optimal operating range 194°F to 1,022°F
• D.O.T.-compliant stainless-steel braided brake lines — stops expansion under pressure for firmer pedal feel and quicker response
• CNC-machined carbon steel caliper brackets for direct bolt-on fitment to OEM bracket locations
• All required hardware and owners manual

Brake Pad Performance: The included NAOC Ceramic pads deliver optimal braking performance for street and occasional track use, producing 50% less brake dust than race pads while significantly reducing rotor noise and wear.

All Ksport SuperComp Big Brake Kits are built to order and backed by a 12-month manufacturer's warranty covering defects. Note: This kit is designed for 2WD vehicles. OEM handbrake function will not be retained.
