As RR says .. don't expect a big difference in the ride. I have also driven a a GTi with both 17"'s and 18"s, and agree with RR comments. The tyre brand nearly made as big a difference as the size of wheel (to the ride). What tyres are you currently on ?
IMHO 17"s do look a bit too small on the GTi, although I'm sure they will fit OK
