Ur-quattro alignment data

[quk@isham-research.demon.co.uk (Phil Payne)]

>From 000.5147.31.20

Amendment: The specified value for total toe of the front suspension
given on page 44-03 of the Workshop Manual should be


   0 degrees +5'/-10'   AND NOT    0 degrees +55'/-10' as printed.

For the purposes of completeness, we are now printing the entire wheel
alignment data.

[Yadda, yadda.  Note the specific statement that the vehicle must be
 unladen.  Also, at least 1000km and preferably 2000km should have been
 driven since any coil spring or strut work was carried out.]

Anyway ...

  Front:

  Total toe (wheels not pressed)        0 degrees +5'/-10'
  Camber (straight ahead position)      -50' +30'/-30'
  Total camber delta left/right         max. 30'
  Toe angle difference at 20 degrees
      lock both left and right          1 degree 5' +30'/-30'
  Caster                                1 degree 30' +40'/-40'

  Rear:

  Camber                                -30' +30'/-30'
  Total camber delta left/right         max. 30'
  Toe at each wheel with specified
      camber                            -5' +5'/-5'
  Total toe at specified camber         -10' +10'/-10'

Anyone who thinks they can get _THAT_ right with string and sealing wax
is deluding themselves.  Note that these are tolerances - the manual
specifically states (twice) that the nominal values should be achieved
as closely as possible.  Five _MINUTES_ of arc with string?

As a benchmark, high-grade glass photographic filters are only ground
to 4'.
