Thanks for the sites! I'm starting to look for a set of Wheels for my 3.0si and are totally clueless on what / how to go about getting the correct backspace/ET. I kind of like the idea of staying with the same wheel size but changing the backspace so it's slightly more aggressive... but I can be convinced to move to a slightly wider wheel as well so I can run a slightly wider tire. I do not want the Hella flush look though nor do I want any rubbing.

I'll be able to study for a bit with these and hopefully figure it out.
