Thanks,
My wife is already fed up with all the wheel and tire nonsense so susp work is out of the question. I actually think that the OEM sport susp is pretty close to perfect with regards to ride height. I would only want to lower it .5in or so and would only consider coilovers which are not in my budget right now. Coils would be more than I think I want to do on a 5 year old car with 48K miles. I am going to drive it like this until I sell the car. I would like to get back into something that says M on the trunk.
Did you lower yours Dav530d?

That rubbing in front was not on outside...more likely rubbing liner due to wrong original tire size you used. 9" ET24 with a 245/30/20 could not possibly rub outer edge. Your inner clearance would be 12mm less than an oem 172 setup like on my car with 245/35/19...exact same outer clearance but 12mm less on inside...or 18mm less than a 166 wheel with 245/35/19. So going down to a 245/30/20 is a perfect fix. A 5mm spacer could also work.
As for the rears, a 285/25/20 should just about be perfect on those sized wheels...certainly could not go wider without rolling. 285/30/20 should work too. It's simple math, not guessing.![Cool](https://5series.net/forums/images/smilies/cool.gif)
In the end it looks like you figured it out the hard way.

Thanks for the input, but with all due respect, I think you missed the first few posts. The front right rubbed on the outside against the spot the fender and bumper meet with the 245/35. The fender was cutting the tire but just to be sure, I put blue painters tape all over the fender well to see if it rubbed anywhere else. I rolled the fenders and it still rubbed. I dropped down to 245/30 in the front and to keep the overall rolling circ the same I went to a 285/25 rear. While I wish I had the extra sidewall, the setup no longer rubs. There was/is no rubbing on the inside, forward or rear fender liner, or strut with either size...
While I would like to say that it is simple math, many members of this board seem to have different experiences with similar/same setups on different cars. There are several people on the board that I have spoken with that have/had zero rubbing issues with the same OEM wheels on a sport susp car with the 245/35 size. The only explanation I can come up with is variations in sidewall by brand and suspension age and or small variences in fender/bumper alignment. Things obviously settle/wear over time. I think I was within a couple mm of not having a rubbing issue.
Definitely a learning experience...there do not seem to be any universal truths in plus size wheel configs.
