I do disagree (a little), but the list knows that!! (ta da da ta, defender of the mighty Swing Spring, but I digress :-}) The reality is that the sag that is common in the later spitfires is probably due more to poor spring materials or even a spring that is slightly overstressed. A spring, basically if not overloaded or over stressed, will not change its character much when in use (look at how long typical vehicle springs last). However if stressed too far it will lose its properties no matter what it is installed in. There is nothing wrong with the spring swing design, it actually works quite well, and I have one in my Rotoflex style equipped Spitfire, but a couple of factors probably lead to the sagging problem. The longer axles of the later Spitfires put greater leverage on the "same" spring I believe is one of them. The uprated spring Andy just mentioned will help. I've got one in my car and the rear sits up just fine (actually a tad to high for my taste, I'm still waiting after a couple of years for it to sag a little) *************************** >Unfortunately, it is "the nature of the beast".
