I currently have 513 M wheels for sale. Only 3k miles on them, 1k miles (basically brand new) Michelin Super Sport tires on.
Tire Size: 255/40/18 (FRONT), 275/40/18 (REAR)
The tires do fit on an aftermarket suspension.* (NO RUBBING ISSUES!)
These wheels previously were from a F80 M3, since then I have changed the tires and had the wheels coated with Nanolex by Detailer's Domain.
Please DM me if interested!
