Streetable track day alignment specs
I'm looking for an alignment that is good at the track and I doesn't need to change it again back on the street.
The car is a Z-51 coupe with stock SIZE tires running kuhmo XS tires. Everything else is stock as far as shocks, ride height, wheels.
I'm not sure that alignment is a realistic or worthwhile thing to shoot for as changing the alignment just enough to be better on the track but not significantly affect street handling is worth making an alignment change if the alignment is already good.

That is a difficult task! That being said, we have spent a lot if time developing our alignment guide and can offer some assistance. The guide can be viewed here:

I would recommend the Performance Street or the Performance Street-Track use. The track use setting can result in some inner wear if you drive mostly on the street. Ultimately, the two will play against each other (street settings/track settings), but you should be able to find a setting that is a good compromise between tire wear, and performance.

Last season I ran with the Performance Street alignment, after 6 track days I found I was wearing the outside of the tires, not the inside. I suggest the Performance Street-Track may be a better compromise.
Keep in mind your skill level comes into play too - the higher your skill level (and higher run group), faster you go, you'll need a more aggressive alignment to get the most out of it. I'm using the pfadt camber adjusters - I love the fact I don't have to worry about losing camber adjustment while driving on the street but it does make wheel alignments more expensive due to the extra labor involved.
Also for street use and whatever you decide, I suggest you go with minimal toe to help decrease tire wear.
Please correct me if I'm wrong but it seems toe adjustments can effect tire wear more than camber adjustments.
