What are the pros and cons of either offest? Whats the standard F-Body offset?
The 38mm offset will give you a wider stance than the 56mm (if this is backwards, someone will chime in). While this may have some fenderwell clearance issues, it will give the car a wider stance by almost 1 1/2" total.
No, you're correct. Roughly 6mm is equal to a 1/4". The lower (numerically) the offset, the more inboard the wheel.
I have 48mm offset Borbet Type T 17x9.5's that fit great. I can't imagine a 56mm. It would definitely do nothing to fill out the wheel well. I even keep my 1/4" spacers on in the rear even when I'm not running my 17x11's.
Lonnie, my thought on 17x12's in the front. While it might provide a more stable platform for the 315 tire I would think the extra mass would negate most if not all of that advantage. Plus the fitment would become a major problem. I guess if you spent the extra bucks to get a very light wheel you might be ok. For me to run a 12" I'd have to raise my front end up. And while I'm probably too low for optimium handling I like the way it looks. I know, a major contrdication from someone how wants great handling but this is a daily driver too. But with the 17x11's (or the 9.5's) I can't tell you how many people have come up to me and said "That's the way GM should have made all the F-Bodies".
