ALIGNMENT SPECS
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
Guldstrand recomends for racing:
(assumes "Guldstrand mod" is done)

Caster 3 to 4 1/8 deg pos
Camber 1.5 to 2 deg neg
Toe in 1/8" out to 1/8" in (I would try 1/8" out first) more neg camber
= more toe out.

Herb Adams recomends these alignment specs for the street:
1 degree positive caster ( I would use 3.5 degrees if PS)
1 degree negative camber.
1/16" toe in

Stock factory alignment specs:
Caster +1/2 deg
Camber + 1/4 to 1/2 deg
Toe-in 1/8" to 1/4" (Radial tires need less toe-in, use 1/8" or less for
them)
