I've got 17x7 fronts and 17x8 rears with 40mm offset on all of them. They're almost exactly lined up with the body in the front and rear. I don't think I could have done much better; perhaps another 5-10mm offset in the rear, but that's about it.
General concesus is....it depends on what you want. Some people just want the biggest wheel they can fit, some want a balanced suspension, some want the cheapest they can find, some want a specific design. I wanted a very neutral balance between the front and rear (no understeer or oversteer in stock form)...and I definitely got that. I'm hoping to use my swaybars to dial in a little oversteer later, but for a daily driver the neutral setup is nice.
I ended up getting Konig Tantrums with Kumho Ecsta 712s, by the way. I wanted some TSWs originally, but was told that their wheels are usually heavy (they were about 2 lbs more per wheel), and that their offsets aren't always exactly as advertised. I am glad I went with the Tantrums, as they suit my car better than the VX1s I was going to get.
Oh yeah, I got my entire wheel/tire package from discount tire for 1150 bucks...very good deal for what I got.
