I rang the man at King springs to ask him what was available. I asked for a specific rate and he said that he didn't have a clue. I asked him about spring rate and frequency and he said all we do is use the oem dimensions and make them shorter for lowered springs, make them longer for raised springs. and just use a thicker wire for performance springs...no science just sell. I hope they have improved from that time. I'll be having my next set of springs made by Jubilee springs at gosford...they know the maths.
