<VV> early suspension changes question

[Ramon Rodriguez III]

First of all, thank you very much to all those who responded to my numerous
recent inquiries (most of which pertained to my recently started 62' Monza
Coupe resto).  I can't begin to tell you how much help I've received here on
VV over the years, and how much that help has encouraged me to delve deeper
into the Corvair hobby.


Now on to my newest question.  Over the past couple of years I've become
very very interested in Corvair history and started trying to read and learn
all I can.

Many times now I've heard and read references to changes made in the first
couple of years of Corvair production that were supposedly intended to make
the swing axle suspension "safer".  I consider all Corvair suspensions safe
and essentially all arguments to the contrary to be unfounded, so I'd like
to know how much (if any) truth there is to this.  Did GM make any changes
to reduce the travel/maximum drop of the rear axles (to reduce the max
camber change)?  If these changes were made, why... and were they installed
on earlier manufactured cars at dealers as I've heard some folks claim?

I'd love a full rundown on what changes were made to the EM suspension
during it's five year run, as well as opinions on what effect they had and
why they were made.

PS- The one Corvair handling criticism I actually consider valid is that
incorrect tire pressure could cause poor handling... in my experience
over-inflated front tires make the car feel noticeably unstable.  Though
this issue only appeared as a result of improper maintenance it was entirely
predictable that this WOULD happen frequently once the cars were in the
hands of the public.  I know I myself have learned that I need to check my
tire pressures immediately after any time my car visits an auto shop...
usually for state inspection since I do almost everything myself these
days.  It's very very common for some mechanic to check the tire pressures
on every car before it left the shop and inflate all four to a standard 32
or so PSI (~35 on trucks and SUV's).  I know when I worked in a garage as a
state inspection mechanic (12 years ago) at 19 years old that was what we
were trained to do.

Thanks all!
