I have run 275/35/18 and 285/30/18 track tires all around on 18x 10 ET 25.
I have also run 285/30/18 on 10" up front and 305/30/18 on 10.5" in the rear (BFG-R1).
I would stick with the lower profile options... the 40 aspect ratio sidewall on the M3 I believe was due to the fact that it does not have wide enough fenders which is not an issue on the 1M.
you should have no issues with the 275 up front (aside from potential rub at full lock - simply take care when in tight maneuvers) not hard to do... and I still have the original fender liners.
I agree with you on the ET... I would get as close as possible to stock as the wider tires will already stick out of the front fender wells a bit.
