Racing wheels?

[Voice of Reason]

I'm having so much fun road racing and auto x-ing this year that I want to get a set of dedicated wheels and tires. I've never had slicks on any car but the idea of more grip is enticing so I'm considering Hoosiers. So my question:

What's better, buying a second set of sidewinder wheels and putting Hoosiers on them

Or

Buying the much more expensive ACR wheels and getting either Hoosiers or the stock ACR tires.

I won't be buying these until after the ACR is out and some reviews of its tires are in but I'm thinking about it now.

And then - am I crazy to then get Corsas vs the normal P Zero tire for my street tires? I like the extra grip they're supposed to provide and the car is only driven in the rain if I get caught in it during an organized club cruise.
