Does anyone know the offset for the front and rear wheels on the 350Z?

Smart!

 

Depends on your model:

Option 1 - 17" - 17x7.5 +30mm (F) & 17x8.0 +33mm (R)
Option 2 - 18" - 18x8.0 +30mm (F) & 18x8.0 +30mm (R)
Option 3 - 18" Rays - 18x8.0 +30mm (F) & 18x8.5 +33mm (R)

Enjoy

 

How would you calculate the correct offset for?

19" x 9wide
19" x 10wide

20" x 9wide
20" x 10wide

PLEASE HELP!!

The calculator looks pretty cool, but so far the only real life 19" packages I've seen are as follows:

19"x8.5J +30mm offset or +35mm offset (F)
19"x9.5J +35mm offset or +38mm offset (R)

Checkout the mega post on Wheels & Tires in the Technical section... it covers loads of options & styles.

I have seen a post with Chromed 20's on 2 Z's but can't shine any light on the offsets etc... Check out arch clearances as well, some cars need their inner arches rolled to provide the necessary clearance to avoid rubbing.

Sorry I can't be of more help - Good Luck
