I will clear some things up. A 15in wheel fits fine some grinding of the caliper might be necessary but no biggie. I have ran a 15in wheel at the track for years. Also It will be fine in the wheelwell as long as your offset right on the wheel. Ditch your bumpstops hit the inner a few times with a hammer to be safe but this is far from too wide. Ive had a 325mt fit just fine so i know these will be ok. Worst case you might need to massage a few areas.
