With the wider tires you might rub with the 15/12 set up if you have passengers, but driving yourself should be fine.

I think I could have easily gone to 15/12 setup... getting the 5mm was a waste, it is hardly noticeable. Trying to measure yourself is not an exact science as it turns out... I don't think you'll have any problems with 15/12 setup fratello-
p.s. I have before after pics, if EAS doesn't mind me posting?
You can surely post the pictures if you have them!
