Upgrade the front brakes on your 2023–2026 Toyota GR Corolla with the GiroDisc A1-268 two-piece slotted rotor set. These fully floating rotors directly replace the factory front discs while retaining the original calipers and braking system.
Each rotor combines a proprietary high-carbon iron friction ring with a lightweight, reusable 6061-T6 aluminum hat. Forty-eight curved internal vanes draw cooling air through the rotor during demanding street and track use, while the floating mounting system allows the friction ring to expand under heat without placing unnecessary stress on the hat.
