Hmm..rotating mass. As long as the weight is matched by performance to us the rim then it shouldn't be an issue, if the rotating mass is greater by weight than the 'stock' set up , it can have a huge impact on 'performance' such as 0-60's , brake wear and tear , bearings , etc.
I think anything over a 16 is too much for such a puny vehicle which is why I am sticking with those as the 16's I have are obviously bigger than the stock 14's but they weigh in at 9 lbs less each with tire.
But for show and what not 18's are ok I suppose. That rim looks heavy as a mudda fugga though.
