I have coil overs on my '31 and am curious as to what happens to load capacity when they are adjusted. Since there are several past and present racers here thought I would ask.
OK - the rear coil overs are TCI's All American and with each, I believe, 200# springs (but don't hold me to that figure - I need to try to find the color code). There is approximately 3" of adjustment - with them currently set +/- an inch from the bottom. Now say that I want to increase rear end height/rebound, I'll move them up some amount. Since I believe that the springs are variable rate, what does that do for their compressibility? Does it in fact change those 200# springs to say, 225#? Why do I need variable rate springs? Or don't I need them? These are a bit soggy where they are with the almost full '32 gas tank? Should I just invest in some -- say 250# springs rather then fool around with 'squeezing' these? If I buy different rate springs, who should I buy them from - TCI is way too slow shipping and these appear to be "standard" 3x10 inch race car type springs.
