Ive heard that but apparently the new GT-R is rolling on 20's and the performance on that certainly has not been hindered
yup the difference being that the car was prob developed to use 20's so the suspension steering etc is dialled in for it
Ahh, so if you get 19's on the Z and change the whole set up of the car so that it will accomidate the wheels in motion, it could in theory perform as well as if it was on 18's? Would be pointless with how much money youd have to spend I know but its just so I understand
hmm in theory.. yes but just consider the 10's of pounds that datsun spend on R&D with a new car !! testing and developing all the supension, chassis etc etc etc
BUT their development is always a compromise between comfort and performance you COULD get it to perform much better but at the cost of comfort
til they have only 40p left in the budget to do the interior
