My opinon echos what's generally been agreed on here.
Buy a car with 18s on. Get a cheap set of Monza 17s to run over winter with the appropriate rated tyres.
Where the 17s may look fine on a GT model with its standard bumpers, the GTI has big fat bumpers that look a bit silly with small wheels. Askers meat and two veg analogy sums it up pefectly.
18s are a must on MK6 GTIs.
Penguin's 17s just about get away with it as they're black (but would look a lot better with 10mm spacers on the back IMO

)
I bought my GTI with 17s, it wasn't a planned act as such; I just got a good deal on it (ex-demo). When I got it home I hid it away in the garage for two weeks until I had time to put my 18''ers on that I had in storage waiting. Sorry, but it just doesn't look like a £25k+ car with the plain jane standard silver Monzas on. The Monza Shadows are like diamond earrings and just add a touch of class as well as visually balancing the lines of the car out.
So in a basic answer to your original question: f**k knows, but if there is a difference it won't be big enough to make a hint of difference how the car drives in normal road conditions if you change your wheels.
