What alignment settings would make the front of the car feel "light" ? This happens on the highway, but at not what I would think are high speeds. 75-80 on up. Is this an alignment problem or something else?

 

If "light" is another way of saying "wander" or that the car wants to deviate from a straight line without driver input, then the problem may be that there is excessive toe-out. This would normally also be indicated by scuffing on the tires. Another possibility is Caster. Insufficient caster can cause a similar problem but without the tire scuffing. With adequate caster the vehicle with return to the straight ahead position after a turn without input from the driver.

 

actuallly when I said light it really feels that I need more front downforce. I have 122kmi. stock susp. old avsi's and questionable ball joints. would any of all of these contribute to this feeling i'm getting.
