For those who were interested, the wheel offset on the Z32 Naturally
Aspirated is 45mm fornt and rear.

Z32 Twin Turbo is 45mm front, 35mm rear.

Now, an interesting question comes to mind:

When we increase wheel size for 16 inch to 17 inch or 18 inch, what is the
correct offset for the Z32 ? Everything changes when going to Plus One or
Plus Two sizes.

Exactly as I've posted..

The important thing isn't diameter but rim width (7,5",8",9"... etc)
If you use stock rim width (7,5 front and rear for NA, 7,5 front and 8,5
rear for TT) you can also use stock offset; if you use wider rims you'd
better to use a lower offset (wheel outer) to avoid interferences with
steering /suspensions arms or body.

Stefano,

I own a Naturally Aspired 94 300Zx and I'm looking at 17 inch rims with a
7.5 inch width
for all 4 rims. Will I need to use the same or lower offset rim ?

Some websites match wheels to vehicles to determine fitment, mainly to
clear the calipers and of course many custom wheels today are for front
wheel drive autos since they dominate the market now.

One wheel shop said if wheels are off the centerline axis, they will not
travel straight and will wear unevenly. The guy would not say whether
those wheels would affect the handling characteristics in the curves.
Thanks.

First of all you need a design that can accomodate easily big front
calipers; since you increase by 1 inch diameter you shouldn't have to worry
about that, unless you choose a very particular design.
A 17x7,5" rim is pefect with 45mm stock offset, you can also use 35mm offset
front and rear to have a wider gauge, more handling in curves and more
"sporting" look with wheels outer, but you will probably have more camber
angle in wheels alignement (the tyres will worn earlier the inner tread
part) so you'd better to close the toe-in to compensate this and have normal
tread consumption.
In my TT I have 17x7,5" offset 35 front with 235/45 tures and 17x8,5" offset
30 rear with 255/40 tyres having 1,2 front toe-in instead of 0,0~0,6 stock
range and doing so I have perfect tread consumption with great agility
approaching curves.
Bye

Stefano,

Tire wear is also a concern, many companies will match wheels that will
fit but they will wear unevenly because the same offset may or maynot work
if I use a wider wheel because the vehicle will not drive a straight line.
If the width increases, then the offset may need to be changed to keep the
pivot point of the wheel in the same place. Or as you said, changes to the
alignment.

Some wheels are matched for certain vehicles and other are not, even
though they fit and clear the calipers. Tires cost too much and rising
oil prices will keep prices up. Thanks

William
