I plan on getting coilovers as well camber/caster plates and would be willing to roll the fenders but still want to be able to have full lock to lock turning ability of the front wheels as these will be the daily wheels that will get to see a few HPDEs and Autocrosses.

Taking into account the cost of tires, measurements, and their availability it seems that I would want either 9" or a 9.5" front (I would prefer the 9.5" but do not know how difficult it would be to fit with a 255/35-18 vice a 9" with a 245/35-18) and likely a 11" in back all on 18" wheels. On a side note, if I did want to track this car more I would probably be interested in a set of 10" fronts and 12" rears down the road but right now don't see myself hacking the fenders at this point.

Could you all help me in figuring out what widths and offset you would recommend running as well any other insight you all might have?

I do however have 11mm of shims on my front LCAs which pushes the wheels out increasing camber and widening the track. ET40-45 with a 18x9 works well. This is what the set up looks like to give you an idea:

Ride height is 1/2" below GT2 at 101mm front and 120mm rear. If you stick with ET 45 in the front with 9" wheel (as opposed to 40) you will have good clearance. Hope that helps

I'm getting new rubber soon and will look at the offset (should be on the hub as I recall)
