Got it. Didn't realize you were puting out that HP. I assumed it was stock.

 

So here are the new specs I'm looking at:

17 by 8 225/45/17
17 by 10 265/40/17

Not sure of offsets yet. Probably +40 front and +48 rear

 

As you are actually looking for function you better stick to a bit more conservative offsets. While people on this board have made rather crazy offsets fit on the car, they usually have done so by running tires that are too narrow to benefit from the wheels on which they are mounted.

 

I am probably going with a +40 front and +50 rear offset. That isn't that crazy of an offset.

 

Here is what I am going to run:

17 by 8 +38 Front 225/45/17
17 by 10 +47 Rear 265/40/17

I am going to roll and possibly pull my fenders. I might go down to a +45 rear maybe.
