Front: -1.2 camber, 0 toe, 8.0 caster. Rear: -.8 camber, .20 toe in. Gives good tire wear for the street with good track performance. If i wasnt too concerned about burning through nitto 555r2s all the time from street driving I'd run a little more negative camber front and rear, say.. -1.5 front, -1.0 rear.

Not sure if you have a C5 or C6, but this is some good info from the C5 Track Car/HPDE Conversion sticky.
For the newbie dual purpose street / track HPDE car with NON slicks a good place to start (rubber bushings and street tires):
======> Camber, Caster, Toe
Front:==> -1.6, 8.0, 0 Height at Mid Fender: 27 3/8
Rear: ==> -1.0, N/A, -1/8" Height at Mid Fender: 27 7/8
More Aggressive (Poly Bushings & R-Comps) - Track Car as much or more than street
======> Camber, Caster, Toe
Front:==> -1.9 (left) & -1.8 (right), 7.5, 0 Height at Mid Fender: 27 (FYI this will scrape your Cats on steep driveways = be careful)
Rear: ==> -1.1 (left) & -1.0 (right), N/A, -1/16" Height at Mid Fender: 27 1/2 - 27 3/4 (Differences occur when you drop weight in front)
* asymmetric camber is because most tracks are run clockwise and this accounts for the increased loading on the left side a bit more for more even L v R tire wear and easier rotating and flipping of tires.
If you want to learn how to do your OWN alignment you can read a great thread here with links to all sorts of useful tools, settings, setups, etc. (http://forums.corvetteforum.com/auto...ich-tools.html) and a few quick links:
Hardbar Alignment Tool is great: (http://hardbarusa.com/hardbar/produc...products_id=44)
DavidFarmer on the CF has a great guide: (http://www.davidfarmerstuff.com/align.pdf)
And have an accurate and good tape measure, laser level or 4" level, builders square & a flat level spot makes it easier to perform your calculations and get the job done faster. Oh, a four post lift is always best :-)
Inexpensive slip plates for doing your own alignment can be found here: (http://www.prdonline.com/osc/catalog...products_id=79)
