Doug, Larry,
I think I know what you meant to say Doug, maybe not, but what I think you
meant was "positive caster", which you get by adding shims to the rear
upper A-arm "shock tower" mounting bolt. I might note, as others have
previously, that the Shop Manual does not condone any adjustment in caster,
only camber, because they use a double shim that fits over both the front
and rear A-arm bolts. HOWEVER, many - perhaps even most of us have ignored
this and adjusted camber and caster separately without ill effects (at
least any I've heard of). Now, everyone probably has a little different
recipe for their own favorite setup, but I have been running with -1.75
degrees of camber and find it works out about right for my mostly street
driving. I'm actually a little surprised I don't wear the insides of my
front tires more, but it works for me with 205/50-15 tires on 7.5" wide
rims. I wouldn't recommend quite this much camber for most people, but
anywhere in the -1.0 to --1.5 degrees is probably going to work pretty well
and not cause very uneven wear. Besides, how many people ever actually wear
out their tires anyway?? Any tire over four or five years old should
probably be retired regardless of how much tread is left. What most of us
need are tires with a tire wear index of about 80. ;-)
TTFN,
Bob
