no, the rims generally do not "push" the car up because the tire sidewall height is generally decreased when you get bigger rims. For example, stock aspect ratio is 55, whereas when people get 17's they usually get 40, sometimes 45, sometimes 35. So whereas the rim size increases, the tire size decreases.
www.preludecrazy.com will give you all the actual diameters of different setups - there is a link on the left menu called "tire diameters". You can bump up your overall height a little but you shouldn't do it too much. So try the kit and if it scrapes, you could get 17's with a 205-45 and then you'd be bumped up a half-inch or so.
