Some cool info from the supplier Edelweiss:
We’ll be running 20” front and rear, which you can combine with either 275/30 R20 in the front and 285/30 R20 in the back or 285/30 R20 in the front and 295/30 R20 in the back.
The wheels will be under 21 lbs each, clear all factory brakes incl. the carbon-ceramics and be compatible with BMW’s genuine tire pressure sensors and lug bolts.
The wheels are done development, yes. We had access to a few BMW factory development cars a few months ago, which we used for 3D scanning, test fitments and development of our wheels.
The wheels are custom designed and weight optimized just for the G80 models. Currently, the wheels are in production. Deliveries will start end of May. Pricing in Canada starts at $5,390 CAD per set incl. door-to-door shipping.
