Having been here since I joined 9 years ago last month (damn time's flown by!) this has been beaten to death and you'll find at least 40 separate threads about it if you do a search. 180 is the widest anyone's gone, it does change the handling since the rear now has a different profile than stock, the jury is out on the few that have braved it on whether it was a negative change in handling or just neutral. It's a cosmetic change that to me carries too many potentially adverse non-cosmetic changes to bother. If you took the time and had the engineering mindset, you could potentially find the right sidewall height with a 180mm tire to maintain the stock profile.
