That awful tuck-under thing was cured by fitting the "swing-spring" rear suspension, and although my donar Spitfire was an
early mark IV, before it came to me it had been retro-fitted with such a spring.
Giving it a few more degrees of negative camber, by lowering the spring in the uprights, really sorts the problem out.
