GiroDisc's front rotors are two-piece, fully floating replacements for the factory GR Supra front rotors. Splitting the rotor into an aluminum hat and an iron ring cuts unsprung and rotating weight, and the design helps the brakes stay cool under hard use.

What you get

  • High-carbon iron rings machined from a casting made to GiroDisc's spec, for better durability.
  • 72 curved vanes that pull air in through the hub to cool the ring.
  • 6061-T6 aluminum hats with a black anodized finish.
  • Cadmium-plated, high-strength steel drive pins to resist corrosion.
  • Made in Bellingham, Washington, with hats, rings and pins all machined in-house from US materials.

Good to know

  • The hats are reusable. When the rings wear, replacement rings (part D1-307) bolt onto the same hats.
