offsets

Hey all, I know this has been talked about, and I have searched ... I'm just looking for some clarification. I recently ordered some 20x9 wheels with a +30 offset - wanted square setup for AWD. (and, yes, I know people run the staggered as long as the circumference is the same and what not...)...

Has anyone done this yet? I've been reading for the last hour and have found nothing. Wrong keyword searches? Perhaps. Getting intrigued by mathematics while looking around the site. Definitely. I'm interested in dumping my 2013 Genesis Coupe 3.8 R-Spec SEMA projects that I purchased in...

For those who ride staggered, what are you offsets for your setup?

Went to dealer today for service and noticed a sign in the lobby, All 2009 Genesis include 1 year of carbon offsets (based on 15k miles). I didn't know about this when I bought, but it is nice to know....
