Front Suspension Alignment Geometry For The Street?
 

I'm probably going to bring my car in to the alignment shop next week and although there seems to be plenty of information (and a couple of stickies) on geometry for the race track I was wondering what everyone has found is the best for the street.

I remember seeing a post around here somewhere about NOT using the original factory settings and I believe it had something to do with Bias vs. Radial tires. I can't seem to find the darn post though.

I have pretty much all brand new or rebuilt components in my front suspension (besides the springs themselves). What numbers should I have the guys at the alignment shop set the car to?

Thanks!

David Pozzi has done a lot of research on stock first gen stuff and I recommend you go to his site for info.

Onto alignment, taken from his page:

David's Specs
Caster 5 deg positive, or as much positive as you can achieve up to 5 deg, can use .5 deg additional positive on the passenger side to compensate for road crown. A common setting would be: LF 5 deg positive, RF 5.5 deg positive.
Camber -.25 degee for mostly freeway driving,
-.5 for street and frequent hard cornering or mountain roads,
-1 deg for street, Autocross, and Open Track, this will wear the inner tire tread if you drive a lot of freeways. I use -1.5 deg quite often on cars that we frequently autox and do only a little street driving. you can use even more if tire temps show outside edge of tread is hotter than inside after a track run. If the inner edges of tread show excessive wear, use less neg camber. An autox only car would use -2 to -3 degrees. If you have not done the Guldstrand mod, you can be more agressive with negative camber and increase neg camber by another -.25 to -.5 degrees.
Toe in, 1/16" to 1/8".

Guldstrand recommends the following specs for a "touring car":
Caster: 3 - 4 degrees positive (+) PS = more, manual steer less.
Camber: 1/4 to 1/2 degrees negative (-)
With upper a-arm relocation Camber: 0 degrees
Toe-in: 0 - 1/8 inch

I have used this on many cars and trucks without issue

Camber- 0.5 to 1 degree negative
Caster- 3-5 degrees positive
Toe- 1/16" to 1/8" toe in

Thanks guys! That's really helpful!

She's aligned and I drove her home. Quite a bit to do yet, and some bugs to work out but getting close.
