Girodisc A1-307 Front Rotors for Toyota GR Supra

FITMENT: Toyota GR Supra (348mm), front

This Girodisc two-piece rotor set is a direct replacement for the front rotors on the Toyota Supra GR. Girodisc two-piece, fully floating rotor assemblies help shed unsprung weight and rotating mass from the front axle of the Toyota Supra GR, while being far more durable in track use.

American Made With Specially Formulated Materials

Girodisc rotor rings are machined from a proprietary casting made of high-carbon steel formulated to Girodisc’s specifications. This superior metallurgy results in a rotor that holds up better, and the 72 curved vanes act as a centrifugal pump pulling air in through the hub to effectively cool the rotors under hard use. The two-piece design means the reusable hat which can be attached to new rotor rings (part number D1-307) when the latter need to be replaced.

All major components including the hats, rotor rings, and drive pins are manufactured in-house at the Girodisc facility in Bellingham, WA, from domestically-sourced materials. The hat is made from 6061-T6 aluminum and coated in a black anodized finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and Belleville washers for race-ready float while also being street-friendly with no noise from loose hardware.

We also recommend replacing them if a crack leads to the edge of the ring.
