- Description
Enhance the braking capability and heat management of your 2023+ Toyota GR Corolla with the GiroDisc Slotted Front Rotors, engineered as high-performance 2-piece replacements for the factory front rotor setup. Designed specifically for the GZEA14H chassis, these rotors dramatically improve thermal stability, pad bite, and overall braking consistency during spirited or track-focused driving.
The 2-piece design pairs a lightweight, CNC-machined aluminum hat with a high-carbon alloy rotor ring to minimize unsprung mass while maximizing cooling efficiency. The slotted surface pattern helps evacuate gases, dust, and debris, ensuring optimal pad-to-rotor contact and consistent braking feel.
Whether your GR Corolla is tuned, tracked, or daily-driven with spirited driving in mind, these rotors provide a measurable upgrade in both performance and durability.
These GiroDisc 2-piece rotors are a direct replacement for the front rotors on the Toyota GR Corolla and Yaris. Our 2-piece, fully floating assemblies help shed unsprung weight and rotating mass from the front 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 holds up better, 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 D1-268) 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: Sold and priced as a PAIR. 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.
