I run the m3 arms and i have 264's with a 10mm spacer and stock 135i tires all around without rubbing while being lowered on eibach springs.. Though my fenders are pulled and rolled. I think the front 264's are 18x7.5 et 49, so mine are at et39 with the 10mm spacers.
It'll be a close call but some massaging of the fenders/camber plates would definitely clear it up. I don't think the added width of the m3 control arms will hurt you since they add more camber where it would rub at the top of the fenders.
