C7 Grand Sport offset question
 

Apologies if this has already been posted.

I need to replace my OEM rims with forged. I've read that the stock offset is somewhere around +43 front, +59 rear. What sort of impact would I experience if I went with Front: 19x10 offset 30 and Rear: 20x12 offset 50? I'd like to keep the look and ride experience similar to what I have, and this seems like quite a big difference.

You’d be much better off asking a forum rim vendor than asking us yahoos. Try Forgeline. Gerry is the guy that is on this forum. You can trust his answers.

Thank you sir. I left him a voicemail.

You would vastly improve the looks and not affect the ride.
+50 in the rear is not aggressive enough IMO, but perhaps you're not looking for flush (+26, +42).

Im also interested in what is the max and min offset we can run front and back. I'm in love with the rohana rfx11 wheels but can't seem to find them for gs/z06 fitment

I would prefer the wheels to be as wide in the back or wider, and not sacrifice ride. When you say "vastly improve the looks", can you please elaborate?
