Just got the front end aligned, everything OK except the caster should be about 1.50 deg to 2 deg. Mine is at .38 on one side and .27 on the other. I have the factor 2 deg shims installed. My springs still have some arch to them, So do I find 3 deg shims or do I go with 4 deg.? Running radials. If I go with 3 deg I will be close but no cigar. I think 4 deg will be to much.
