The only adjustable parameter is toe. camber and caster are fixed. Values
for camber can be changed by using camber plates or use the BMW "correction"
strut mounts, but these items only add/or subtract a fixed amount of camber.
I have an 88 ///M3 with Bilstein sports used as a daily driver with some
driver schools and some autocrosses, I'm using the BMW correction strut
mounts to remain in "A stock" class, but the same thing could be done with
Dinan's or Korman's camber plates. The car likes negative camber but, daily
driving with a bunch of negative camber will kill tires quick. A good trade
off seems to be -1.5 degrees. I also have the offset control arm bushing
which add caster for additional high speed stability (not noticable) but will
allow the fittment of 225/45R16 tires with 20mm offset wheels. I have my car
set up with zero toe. The car is a little twitchy, but the turn-in response
is very nice. I would recommend trying 1/16" total toe in as a starting
point and see how you like that. I good alignment shop should adjust your
toe settings for about $20.
