Front Wheel Alignement - Settings?

Need to get the front aligned properly ... looked up the spec for our cars in a couple of books I have and they all list different specs ...

Anyone got some good recommended settings I can give the guy doing the alignement for me?
 
For spirited driving...1/2 degree of negative camber. Caster around 4-1-/4 and 5 -1/4 degrees positive. This may give a heavy feel in the steering wheel. Toe in? I think 82-92 are at 0 but I'm going to try a degree or so in next summer.

This is how I had the '92 set up last year.

Got those specs, see below, just that when I do a search most people say the factory specs are crap and should not be used and looking at different settings for the 89 TA there's a number of different ideas what the factory settings are supposed to be as well ...

The Helm manual list the following (in degrees):
Camber 0.30 +- 0.50
Caster 4.70 +- 0.50
Toe 0.00 +- 0.10
 
Jan,
Negative camber helps the front end in turns. Try to get -.5 if you can. Some of our cars will not allow that much adjustment. The side effect is if the car is a daily driver it will wear out the insides of the front tires quicker. If it is a daily driver then go to a camber of 0.

Whan I used to Autocross my 89 GTA I would set as much negative camber as possible (-.75).

I agree with Dave on the camber, caster at stock, or less, toe 0 to .06 toe out for tight turns like AX and toe 0 to ,03 toe in for slow turns. It is somewhat a mater of taste.

I have had front wheel bearings set too loose that caused "wheel rut hunt" Thought it was tie rod ends, idler arm, bad alignment etc. I tend to run the wheel bearings a little tight. It keeps the disc "wobble" from pushing the pads too far away from the discs and decreases peddle and increases peddle feel.

Happy Holidays all!

Thx Guys, I will take that info to the wheel alignement guy and have him set it up properly for me.

Glenn, the steering gear/box adjustment seem worth while the effort might try to do that before taking the car in for the wheel alignement.

Again, thanks for the help.
