K Sport big brake kits provide the ultimate stopping power for your vehicle. Integrating new brake technology into the design of the kits allows for a kit that highly reduces brake fade and continually cools and refreshes the brake pads surface under braking. These brake systems are designed for easy installation with minimal tools required (in most applications).

The K Sport big brake kit includes:

  • 8 Piston calipers
  • Stainless steel brake lines
  • Machined aluminium hats
  • Carbon steel brackets
  • 330/356mm Brake discs

The K Sport extreme lightweight caliper is machined from aircraft quality billet, weighs just over 2kgs each, and has machined in protection grooves for the bridge tubes. Aluminum pistons, high temperature seals, and stainless steel brake pad wear plates are also standard on each caliper design. The piston caliper design greatly improves pad wear and caliper rigidity over the OEM design. The stainless steel brake lines stop expansion under pressure.

Most applications utilize the 2-piece disc assembly which reduces weight both rotating and unsprung. This design also stops thermal stresses of extreme heat from warping the disc or cupping the braking surface. The unique slot design on the disc greatly reduces braking noise and expels gas and pad debris faster than conventional slot designs. Every disc is always heat treated and balanced before shipment for the best possible performance.

These brakes have been tried and tested on the ID-Workz demo car and we highly recommend them!
