[V8] Alignment specs

I need to do an alignment myself soon and Mr. Cheapskate (and I mean  
that in the most admiring of ways right now) -- Bernie Benz -- uses  
this modus operandi (from a previous post on the 200q20v list) --  
same suspension pieces and track, as you know:

"IMO, the factory nominals and tolerences are designed to accommodate  
minimum wage alignment jockey having no understanding of the basics  
nor of
his maybe sophisticated optical alignment system and of course, to  
sell more

Beyond that of a sound, tight steering and suspension system, my DIY  
for optimum tire wear are, for both Front and Rear:

Camber: zero, +/- 0.1, both sides must be identical, no measurable
Toe:  -0.1, +/-0.1 (Will pull to zero optimum under average drive  
Both sides must be identical with a centered steering wheel/rack. Also,
total toe must be centered on the chassis as measured at the B  
pillars, F
and R. When C and T are dead on, if necessary I will adjust Caster to
eliminate any slight consistent pull to a side. This being an  
initial, first
time adjustment, not necessary thereafter.

This is easily (but initially time consumingly) accomplished with simple
carpender¹s tools on a relatively flat garage floor and will hold  
drift or changes for years. Been my modus operandi now for 10+ years.


I think that's a good place to start at the very least :-)
