alignment Specs for hard street use.

Id like some input(a good starting point) on alignment specs for an agressive street/occasional autoX setting.

Heres all of my mods(maybe a few i forgot) if you need more information let me know.

Front:

-17x8.5"
-Toyo Proxez 4 rubber 245/45/17
-Eibach Prokit
-Tokico HP (blues)
-Billet tie rod adjusters
-Poly end links and sway bar bushings
-Edelbrock STB
-Wonder bar

Rear
-17x8.5"
-Toyo Proxez 4 rubber 245/45/17
-Eibach Prokit
-Tokico HP (blues)
-Poly endlinks and bushings
-Profab LCAS
-Spohn Panhard bar

Ive done a little research, and a few searchs to get some info the first search came up with what seemed like real aggressive settings for street use and a more likely setting. Heres what ive come up with. Can some one tell me what the down falls to either of these settings would be?

Edit: attached a pic for easier viewing.

Anywhere in between those two perameters is ggod for agressive street. Just don't go over them. I would suggest keeping the camber at about -0.75 on both sides and setting the caster at 5*L/5.5*R. Set toe at about 3/32"toe- in

Camber Setting

You will not be able to do too much camber unless you modify the strut caps (top bushing) they can only go so far. I had a front and rear performance alignment done on my car. You need to make sure the rear is properly aligned too. They can adjust the panhard rod and the lower control arms if you put in the adjustable type like those from Spohn. For the front alignment the big question was "how long do you want the front tires to last, 5K or 25K?? Good luck!

Not to steal your thread. but............what are some good specs for a daily driver that likes the twisties? I need an alignment after I swapped all the linkage for Moog w/ hex bar toe adj, bilsteins HD, eibachs pro-kit, GW del-alum a-arm bushings and C5 brakes I also have 17" wheels with BFG G-Force TA KDW rubber.
As mentioned I drive this car daily (when not down for wrenchin) and would like to keep those expensive tires as long as possible. but I do like those highway off ramps too (if you can't tell from what I spent on the suspension). I figure I need some negative camber (like -0.5* to -0.75*) because after the C-5 brakes, which pushed the wheels out 3/10" and my tapemeasure alignment, the wheels rub near the top/front inner wheel well at full lock. From looking around the boards and comments here I figure 3/32 toe-in is good. what about caster? +4.75* left +5.25* right. Will these specs chew up tires? I guess what I am looking for is the best all around performance daily driver alignment specs, that wont chew up tires. Is that too much to ask.
