+40 wheel offset
 

370z 09 touring......can i run a+40 offset up front on a 20x 8.5 and a +40 in rear w a 20x 10? If so will i be flush? Thanks

that will be sunken in on the front and ridiculously sunken in on the rear especially if lowered.

What offset do i need for that size and width stock height to sit flushed

This setup is more sunken in than the sport package wheels. Definitely not flush. Go look at other peoples setups and see what wheel size/offset they used. I definitely haven't seen anyone run an aftermarket wheel setup with an offset in the 40's.

These are fun and should help a bit.

40? That's what you would run on a front drive car.

factory nismo wheels are +40 on the front, but width is 9.5". it's not sunken in, but not 'flush.' it has a perfect tuck imho for stock suspension especially when used on the base (non-nismo).

Mine are 18 and 20 and perfect. 40's , nooo.. Wheels are 9.5 and 11

I think a 9.5 or 10 +30 would fill up the front quite nicely especially with meaty 275 tires. :tup:

that would stick out too much on stock suspension.
