Developed in conjunction with our brake partner Girodisc.  12.2lbs each

Slotted, not drilled

  • Slotted to vent hot gases during hard braking.

  • Slots clean rotor-pad interface and maintain maximum grip surface.

  • Will not compromise structural integrity like drilled rotors that tend to crack.

Lightweight hats 

  • Aircraft 2024-T3 billet aluminum.

  • Grey military-spec hard anodized finish for increased protection.

    • Color of hats may not match perfectly from batch to batch.

High carbon-iron rotor

  • Stable thermal properties.

  • Longer wear characteristics.

True floating rotor

  • Cadmium plated alloy bushings. Grade 12.9 cap screws with spring washers.

  • Much more effective at reducing heat in the braking system than a simple 2-piece rotor.

Heat and stress relieved

  • Additional processing ensures greater durability for track driven cars.

Cool BOTH Sides of your Car

  • OEM rotors have curved vanes for cooling; however, the same rotor is used from side to side on the rear, rendering its effects void on one side.

  • Our rotors are specific to each corner.

  • Directionally curved vanes act as a centrifugal air pump to actively move cooling air through the rotor as it rotates, quickly removing the heat that causes brake fade.

Model Compatibility

  • Lotus Cup Car with Lotus Sport/AP Racing front brakes (308mm 2-piece rotors).

  • Lotus Exige S 240 & S 260

  • Any Elise or Exige that has been upgraded to the Lotus Sport/AP Racing front brakes (308mm 2-piece rotors).
