I'm running 18 inch wheels, came with 16 inch from factory. I have no limiters installed but also no rubbing issues. The only thing that you need to keep in mind is the deviation of your speed indicator. By default (don't know the exact numbers) with 16 inch, 120km/h indicated will be around 113/114 km/h gps speed, with 18 inch installed it will be about 118/119 km/h. At least, that's what I noticed when I switched to 18 inch.
