How low can I go? I'm kind of interested in going with a smaller diameter wheel and bigger tire combo. Is this no go due to brake, etc. rubbing issues etc?
Nice. Those look kind of like the wheels I wanted for my WRX.
For future reference, you can run 17's on V8 brakes, but you have to use a spacer and there's very little clearance. There is a member on here who's done it, I believe with no issues at all. But YMMV.
