The latest Super Street mag has a few articles on offset, wheels, tires, fender rolling, etc. I don't know much of anything when it comes to this stuff so I can't vouch for any of the info, but I did like the pics and explanation of fender rolling and rear bumper tab mod on the S2000.

 

I have an old issue from Sport Compact Car,where they do the weight of the wheels.They need do to do that too...

 

I belive Isaac, our own spunkysandoval is in the issue.
