Think he was on standard wheels and the 18's make a big difference!!
So why is this
Surely if u changed your wheel size u change the profile of your tyre to suit so u end up with the same rolling diameter, or near as anyway, and the little difference there is surely cant make that much difference on accelleration to 60 as it all so quick anyway, can see any difference in diameter having more diff on top end speeds but 60 aint really convinced
That is a please explain question not an argument
