/4's were "a little more than 50"
/6's were "about 60" GT's were 70/80/90 soft/medium/hard There are formulas for determining theoretical rates for steel coil springs - Carroll Smiths' and Paul Van Valkenburg's books have them. An old spring will probably have settled but that doesn't change its rate, just its free length. The table of data with 'what the dots mean' can be found here: Charlie Davis' 914 spring rate web page |
