Does anyone know of a website that has a spring chart(Color-rate) for standard length suspension springs,and or a place to buy them? I made a spring rate-er for my 1/4 scales a few years back ,it was basicly a digital scale and an old shock that could be compressed and the weight could be read,I just made my own chart for my collection of springs,now thanks to an online trade with Timmah I'm into the 5ths scale cars
