GiroDisc offers a range of 2-piece rotors that serve as a direct front rotor replacement for the G80 M3, G82/83 M4, and G87 M2 models lacking carbon ceramic brakes. These meticulously engineered fully floating assemblies are designed to reduce unsprung weight and rotating mass on the front axle, significantly improving the vehicle's handling and responsiveness.

Crafted with precision, the rotor rings are machined from a proprietary high-carbon steel casting, meticulously formulated to meet GiroDisc's stringent specifications. This specialized metallurgy ensures exceptional durability and longevity, even in the face of challenging operating conditions. Additionally, the 72 curved vanes integrated into the design act as a centrifugal pump, actively drawing air through the hub to effectively cool the rotors during high-stress situations. A distinctive feature of these rotors is their 2-piece design, which allows for the reuse of the hat. When replacement is necessary, users can simply attach new rings (part number D1-282) to the existing hat, reducing maintenance costs and hassle.

GiroDisc maintains a commitment to quality by manufacturing all major components, including the hats, rotor rings, and drive pins, in-house at its Bellingham, WA facility. The hat is meticulously crafted from 6061-T6 aluminum and finished with a durable black anodize coating. Meanwhile, the drive pins are constructed from a high-strength steel alloy and feature cadmium plating to ensure corrosion resistance. Rotors are assembled using spring clips and Belleville washers, ensuring a race-ready float while maintaining a quiet and street-friendly operation without any noise issues.

GiroDisc recommends replacing these rings when they reach a minimum thickness of 34mm or if a crack extends to the ring's edge for optimal safety and performance. Choose GiroDisc's 2-piece rotors to elevate the braking performance of your vehicle, all while benefiting from the peace of mind that comes with high-quality, domestically sourced components.
