- Description
Upgrade the braking performance of your 2023+ Toyota GR Corolla with the GiroDisc Slotted Rear Rotors, engineered as high-performance 2-piece replacement rotors designed specifically for the GZEA14H chassis. These rotors provide superior cooling efficiency, reduced unsprung weight, and improved braking consistency compared to the factory one-piece rear rotors.
The floating 2-piece design features a lightweight CNC-machined aluminum hat mated to a high-carbon cast iron rotor ring, significantly improving heat dissipation and reducing the risk of brake fade during spirited driving or track use. The slotted rotor surface enhances pad bite, clears debris, and maintains consistent contact for improved pedal feel.
Whether you're carving back roads or running repeated laps, GiroDisc rotors deliver reliable, fade-resistant stopping power.
These GiroDisc 2-piece rotors are replacement for the Toyota GR Corolla and GR Yaris. The GiroDisc rotors are larger than the factory discs, and we include the necessary caliper spacers and longer caliper bolts to reposition the caliper. No other modifications are necessary. Weighing in at 10.4 lbs per rotor, these fully floating assemblies help shed unsprung weight and rotating mass from the rear axle of the vehicle.
The rotor rings are machined from a proprietary casting made of high-carbon iron formulated to GiroDisc’s specifications. This superior metallurgy results in a rotor that lasts longer, and the 48 curved vanes act as a centrifugal pump pulling air in through the hub to effectively cool the rotors under hard use. The 2-piece design means a reusable hat which can be attached to new rings (part number D2-268) when they need to be replaced.
All major components including the hats, rotor rings, and drive pins are manufactured in-house at our facility in Bellingham, WA from domestically sourced materials. The hat is made from 6061-T6 aluminum and coated in a black anodize 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.
Diameter: 316mm
Thickness: 18mm
Weight: 10.4 lbs per rotor assembly
Important: The minimum thickness at which we recommend replacing these rings is 16mm. We also recommend replacing them if a crack leads to the edge of the ring.
