How bad is this?
 

So I was putting my new wheels on today and had them all the way on with the spacers and after I dropped the car I still didnt have enough clearance in the front to drive forward or backward. So after that I took the front wheels off since those were the only ones that were rubbing on the rotors and left the back ones on(since I didnt have much time before work) by leaving the back ones on that are 18s and the 17 stocks in the front on too and from work will that do any harm to the car for a day? I dont think it will do much of a difference since some people race like that. but was still curioius none the less
