Looking to fit 245/40 and 275/35 extreme summer compound e.g. RS-4 or Star Specs without fender rolling or spacers. The more flush the better but don’t want undue stress on the hub lips neither.
Fronts: 18x9.0 et30 / 18x9.5 et35 / 18x9.5 et28

3002 tii,
We would recommend the following fitment for your application:
Front: 18x8.5" ET35 - 235/40-18
Rear: 18x9.5 ET22 - 275/35-18
OR
Front: 18x9" ET30 - 235/40-18
Rear: 18x10" ET25 - 275/35-18
Please keep in mind that with the 18x9 ET30/18x10 ET25 fitment, a 245/40-18 tire is not recommended. That tire is a bit too tall and might cause extra headache when it comes to front clearance. We would recommend sticking with a 235/40-18 tire for optimum fitment on your M Roadster!
A 275/35-18 in the rear should clear in the rear given your current camber at -1.5˚ but we cannot guarantee this, as every car is a bit different. Ride height and tire compound can play a roll in clearance to the fenders.
The 18x8.5 ET35 and 18x9.5 ET22 fitment listed above will be a direct fit for your application and will not require spacers or fender work, provided that you stick with the tire sizes we have outlined. Below is a photo of this setup with our EC-7 wheels for reference:
