Front end alignment

Pontiac Lee · 01-20-2011, 05:47 PM

Can anyone provide some figures on setting up the front suspension of my 72 Firebird, 455 G stock auto stocker? I have replaced all suspension components including Global West and Calvert products. I am interested in caster/camber and toe-in figures....any help is appreciated....Lee

I have also purchased the new Moroso "trick springs" and wonder if I need to do any cutting on them....thanks!!

All the positive caster you can get, zero camber at the ride height the car is at when it is on a pass, and about 1/16" to 1/8" toe in. This should be done with the driver's weight added to the driver's seat while the car is being aligned. You're trying to get to zero toe and zero camber as the car goes down the track, for minimum drag, and the positive caster makes the car want to go straight, because anything close to zero toe tends to make a car want to wander at least a little.
