Oldsfan Posted March 22, 2011 Share Posted March 22, 2011 The patient is a '62 Starfire. She is getting new sneakers (again), so we will be aligning the front end (again). Last time it was aligned to the specs in the service manual, which, natually is for bias-ply tires. Using a different alignment guy this time and he was to align it for the radials. Something about positive vs. negative caster. I remember reading something about it along time ago. It related to the front wheels of a grocery cart, but I can't remember what I read. He's wondering what other folks are doing about alignment specs for radials.Paul Link to comment Share on other sites More sharing options...

Negative caster will make the car handle terribly with radials.Jim Link to comment Share on other sites More sharing options...
D Yaros Posted March 24, 2011 Share Posted March 24, 2011 As I have a '62 with radials, does anyone have the degree figures that an alignment person should use? Link to comment Share on other sites More sharing options...
Guest Jim_Edwards Posted March 24, 2011 Share Posted March 24, 2011 As I have a '62 with radials, does anyone have the degree figures that an alignment person should use?Dave you can try these as they are known to work well on some '60s cars. Beyond that it may become trial and error for individual handling preference.1. Basic rule - No more than .25 degrees difference between driver's side and passenger's side. 2. +2.0 to +3.5 degrees caster. 3. -.5 to 0 degrees camber. No positive camber, please. There is no problem having a slight variation from driver's side to passenger's side to account for the crown in the road (only a big deal on older 2 lane highway driving. 4. 1/16" to 1/8" toe inJim Link to comment Share on other sites More sharing options...
