I went to get my car aligned and they said they would need caster shims to do it. I have a 98 sedan ex 5sp. That didn't sound right at all, plus they wanted 80 bucks. I have had alignments done for $40 in Texas. So I guess my question is: CAn't they adjust the caster without shims, and what is a fair price a for alignment plus shims, if needed? Thanks.
