edit: Well Im going with 19x8.5 up front et 35 and 19x9.5 in the rear with an et 40 wat will i need to do to get everything fitting write and what tire size do u recommend i was thinking 245/35 front and 275/35 rear
Im new to the 350z world so the whole tire size et thing to me it somewhat confusing
TIA

 

My wheels are 8.5 front 920 offset) rears are 10.5 (35 offset) I'm running excessive negative camber, so the rears should/would be more flush with the camber put back to where it should be.

 

Stay close to 22 for rear to have a flush fitment.

 

so i went wit 19x9.5 for the rear which would be better 25 or 20 et the wheels are 40 et so im guessing ill need spacers

 

I have 19x8.5 +22 and 19x10.5 +20

I would do:

+20 ALL AROUND with those sizes. with the camber in the front you will run lowered, it will look slightly tucked at +22 with a 8.5 rim on a 255/35 tire

tire size is also important when figuring this out, and will affect the stance alot, as tires can fill the gap from rim to fender... but if too small there will be a huge gap.

here is a picture of my rims as described (+22, +20 same sizes as you want):

 

edit to the wheels i decided to go with if all works right please any and all help would be appreciated

 

up?
