Product Details

The Ksport BKBM115-653SO Big Brake Kit delivers the ultimate in stopping power, featuring a floating rotor design with your choice of 4, 6, or 8 piston caliper configurations. Engineered with advanced brake technology, this kit significantly reduces brake fade while continuously cooling and refreshing the brake pad surface during braking.

Caliper Features:

  • Extreme lightweight, one-piece monobloc caliper in a differential bore configuration
  • CNC machined from aircraft-grade billet aluminum — weighs just over 5 lbs. each
  • Machined-in protection grooves for bridge tubes
  • Aluminum pistons with high-temperature seals for reliable performance under extreme heat
  • Stainless-steel brake pad wear plates included as standard
  • Opposed piston caliper design improves pad wear and caliper rigidity over OEM
  • Stainless-steel braided brake lines prevent expansion under pressure for consistent pedal feel

Rotor Features:

  • 2-piece floating disc assembly reduces both rotating and unsprung weight
  • Floating disc design prevents thermal stress from warping or cupping the braking surface under extreme heat
  • Unique slot pattern rapidly expels gas and pad debris, greatly reducing braking noise compared to conventional slot designs
  • Every rotor is heat treated and balanced before shipment for optimal performance
  • Cross-drilled rotors run cooler and are recommended for daily-driven vehicles
  • Slotted rotors are recommended for track and performance driving applications

Designed for straightforward installation with minimal tools required in most applications, the Ksport BKBM115-653SO Big Brake Kit is an ideal upgrade for drivers seeking superior braking performance whether on the street or the track.
