Can anybody tell me if the alignment Specifications for a STS 4 different from a RWD STS? The shop I take it to says there are no differences but I seem to remember that there were .
Well the allowed tolerance variation is so high that the caster could really be the same on both cars.
5.50 degrees with a tolerance of + or - 0.6 degrees
5.85 degrees with a tolerance of + or - 0.6 degrees

Actually looking at Alldata for my 08 STS4 this is what it shows. These are different values than what have been posted.
