How to determine whether offset's will clear?
 

Hey all,

I am looking into some wheels for the G35 which are sized:

18x8.5" with 38mm offset.

I have never seen these wheels on the G, so I have no idea if the offset would clear my brembos. I was wondering if there was any way to tell other than actually attempting to mount them?

If there are any wheel gurus on the site who could help me out I'd appreciate it if you would PM me for details. I would rather keep the wheels a secret since, well, they would be unique. ;)

TIA
