When we discuss wheel alignment TODAY, and when radials are being employed, factory specs are only relevant as a base line. Changes are made by the alignment shop when radial tires are NOW on the car. So take the factory specs into the shop but tell them that was with bias ply tires. I agree about adding a few degrees of caster. I can't think of any circumstance when this is not a good idea on any performance oriented car. Have a friend who ran Bonneville a number of times and there going STRAIGHT is critical! That team ran 15 degrees of caster on their chassis!
