Barry said: "...Because when the angle of the upright changes, and you don't
change the length of the pivot points between the spring eye and the hub on
the upright, the axle is at a slightly different position in relation to the
road. In effect the axle, when lengthened (which pushes the hub out an
inch), shortens the distance between the spring eye (fixed) and the axle (in
the vertical plane). This means the car sits slightly lower (given the same
spring loading), and if the car is lower the wheels camber inwards more
-..."
But, as I've already mentioned a couple of days ago, including mathematical
workings, this causes such a small change in ride height (0.084") - and
therefore camber (0.4deg) - as not to be worth worrying about. My post is

Bill, are you sure about the different length springs?? I was under the
impression that the same length spring was used throughout; the Rimmers
catalogue
http://www.rimmerbros.co.uk/cgi-bin/rimmer?spitfire/susp#Rear%20Spring,%20Fi
ttings%20&%20Shock%20Absorber would seem to support that, only one spring
listed.
