This is the maximum width for the front of your 1M. The 285/35/18 is way too tall and even with an extreme amount of negative camber it will definitely rub on the fender liners with any kind of steering angle. Also the 285/35/18 would look quite odd with that tall of a tire in the front of the car. We have 18x10" ET25 wheels available in both the ARC-8 and EC-7 models as well as camber plates for your 1M!

I was able to fit a 285/30 Hoosier.. on a BONE STOCK CAR .. before camber plates.. see here.
it was VERY close and rubbed ever so slightly but in retrospect.. I think it would work if one is not concerned about minor rubbing... I know that I was definitely a lot more conservative back then as I did not want any fender liner damage. With camber plates.. I am sure these would work.. Might even be able to borrow that setup again from a friend to confirm....
Thanks very much for the info! Sorry it's taken so long to reply. I have been crazy busy at work as of late.
Jeff the Ec-7s are what I plan on getting. Will do Vorshlag camber plates too.
Looking at what tire options are available may make the decision for me. In the 275/35/18 I can get Michelan PSS. Those are pretty much unequivocally the best street tires out there. In the 285/30/18 the best I can find it are Potenza S-04s. I don't think these are as good a tire as the PSSs.
So, I'm thinking for now I'll probably just do 275/35/18 all around. I won't have to do camber plates immediately either which is nice as tires and wheels are going to be expensive.
Once I burn through this set maybe PSS will come in the 285/30/18 size.
