are the specs imprinted anywhere on the wheel? maybe on the inside of the wheel? im lookin at some used slips, but the guy doesn't know the offset or width...

 

just measure them or try them on

use this link as a guide to measure: http://www.rsracing.com/tech-wheel.html

 

on the backside of the wheel it is stamped with the offset and the width....example would be et42 ( which is the offset )....

 

I'm pretty sure the Rota's have a sticker on them.

 

they do have stickers but if tires are mounted on them you won't be able to see it...

 

On the back of the wheel where the bolt holes are...it says what the wheel size and width is and the offset should be there too.

Example...my buddy's say (1565), 15x6.5 and (40) offset. It should also have Rota stamped on there too.
