Cure for rubbing

[four six]

So I put my new wheels and tires on less than a month ago, and I knew it rubbed but not as bad as it actually does. I run BFG DR 315/30 and I know that pre 99 GTs had shorter axels, so what are my options?
Run a spacer?
How big?
?????

Wheel Spacers, or roll the fenders. Depends on where it's rubbing.

Its rubbing on the inner side of the tires

I would say to get a pair of wheel spacers.
