Re: Steering calibration settings
* Caster 5 deg positive, or as much positive as you can achieve up to 5 deg, can use .5 deg more positive on the passenger side to compensate for road crown.
* Camber -.25 degee for mostly freeway driving, -.5 for street and occasional hard cornering, -1 deg for street, Autocross, and Open Track. you can use even more if tire temps show outside edge of tread is hotter than inside. If the inner edges of tread show excessive wear, use less neg camber. If you have not done the Guldstrand mod, you can add .25 to .5 deg to the above camber settings.
* 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
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)
IN ALL POWER STEERING EQUIPPED CASES, USE AS MUCH POSITIVE CASTER AS YOU CAN ACHIEVE UP TO 5.5 DEGREES POSITIVE MAXIMUM. MORE CASTER HELPS TILT THE WHEEL INWARD WHEN CORNERING, HELPS REDUCE BUMPSTEER BY LOWERING THE TIE ROD ENDS. MANUAL STEER CARS WILL REQUIRE MORE EFFORT AT HIGH CASTER SETTINGS, YOU MAY HAVE TO USE LESS.
