Toyota GR Supra, BMW 345mm Rear Rotors

Product Details

These GiroDisc 2-piece rotors are a direct OE replacement for the rear rotors on the Toyota GR Supra with the 3.0L motor, as well as BMW G-chassis cars with a 345mm rear rotor, including (but not limited to):

• G2X M340i & M440i
• G2X with optional M Sport brakes
• G01 X3 M40i & G02 X4 M40i
• G29 Z4 M40i

Our 2-piece, fully floating assemblies help shed unsprung weight and rotating mass from the front axle of the vehicle. The rotor rings are perfectly machined from a proprietary casting made of high-carbon iron formulated to GiroDisc’s specifications. This durable 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 D2-307) when they need replacement.

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.
