A number of Spyder builders have converted their Herald/Vitesse rear end to the Spitfire IV/1500 swing spring set-up;
Using a Spitfire IV or 1500 as a Cordite donor will give you the swing-spring back end as standard anyway;
A Mk2 Vitesse donor will come with double-jointed Rotoflex rear driveshafts;
Or, like mine, lowering a swing-axle Herald or Vitesse by around 90mm means that under hard cornering when the weight comes off one side the wheel reaches the end of its travel before it gets anywhere near tucking under. In the pic below I've jacked up one side but both wheels are off the ground 
Anyway, if you're the kind of guy who enjoys building/driving an Arrow I'm sure the Sammio bug will bite soon...
Oh, and just noticed that in this picture it's kind of simulating a hard left corner where the off-side wheel would actually be under full load rather than dangling as it is but the attitude of the nearside wheel is critical as that's the one that would be in danger of tucking under, and, as you can see, it's almost vertical to the ground at full extension so no tuck under. |
Thanks Towed, I did not know all that. I have just lowered mine with a 1" block and its got 4 leaves removed. This gives a nice ride, I think still too firm though, but also results in quite a bit of negative camber...see pic
MUCH better cornering than the positive camber it had before.
So I have now sourced a swing spring, and once its on can set the mudguards up better. I think it will be to hard, so may remove a leaf or two. Bad idea re tucking?
