Hey no problem. I had to figure it all out for my car, might as well pass it along.
With of course the standard disclaimer that the body tolerances on these cars aren't that great, so when your clearance tolerances get smaller than the body tolerances not everyone will be successful. With the 275's up front on my car, with how it's set up for ride height, etc, I think I'm only playing around with an "extra" 1/4" to 3/8" or so. It's tight.
