Shortening the spring restores a sensible ride height with the new lighter body. The trouble is the spring becomes stiffer, I.e. the spring rate increases. This is the opposite of what you want for comfortable road use. When I built a vitesse based Spartan kit many years ago, the kit maker's instruction was to use herald front springs with the heavier 6 cylinder engine and spifire springs (mk 3 or earlier) with the 4 cylinders. This restored the ride height and matched the spring rate to the lighter body. In those days you could find these easily at you local scrapyard. Happy days!!
