FITMENT: BMW G87 M2, G80 M3, G82 M4 (with 380mm front iron rotors)
The A1-282 Girodisc rotors are engineered to bolt directly to your vehicle with no modifications. They maintain OEM brake balance and work seamlessly with factory calipers and pad shapes, making them the perfect upgrade for drivers who demand more from their braking system.
Each rotor consists of a high-carbon cast iron ring for improved thermal capacity and crack resistance, paired with a precision-machined 6061-T6 aluminum hat anodized for corrosion protection. The two-piece floating design improves heat dissipation and allows for thermal expansion under extreme conditions, ensuring consistent pedal feel and braking performance on track or the street.
The reusable aluminum hat can be paired with replacement rings (D1-282) when needed, making this a smart long-term investment for any enthusiast who pushes their G8X to the limit.
