I got a rare set of wheels for a steal, but the sizes are off. Here are the specs:

Fronts: 19 x 8.5" + 46
Rears: 19 x 9.5" + 43

I just need advice on which spacer size to use. I can either go for 25mm, but have been told to go as high as 30mm. I do not want to fender roll. Anyone with experience or suggestion on the spacer size?

 

We have a section of the forum for wheel and tire oriented questions.

These are terrible specs for a coupe.

30mm front and back will be fine without a roll.

19x8.5 +16
19x9.5 +13

 

I have 20x10 + 25 in my rear and its just missing the lip of the rear fender. (Im also lowered on 350z s.tech) ... Soooo you should be able to do atleast 20mm in the back.

And for the front, I believe yo can get away with a lower offset (bigger spacer) since the front fenders are pre rolled from the factory.
