Justin, Paul,
I have been following your chat about alignment and of course agree that
alignment is another key to a good ride and low tire wear.

I am very interested in the alignment spec modifications and would like
to hear more about drive results experianced by each.

I am the pround owner today of the Hunter (C111) computerized 6 wheel
alignment machine! If I'm going to get into this, I may as well go all
the way! The unit utilises a variable program computer, real time on
screen display of specs as you work and a printout of the results of the
job. I would like to start cataloging the different specs you give me
with their driving characteristics and make each setting available. I
will also be able to recheck the specs easily later, say after a trip,
to see if any alignment changes have occured.

I will be completely set up next week and will let you know how things
progress. This was an expensive investment, so next time you're in
Florida please come by and get an alignment, I need your support!

Business is growing and I'm having a great time!
