I'm finally starting to gather the components for upgrades for auto-x next season. I've got a list of the usual bolt on bits and pieces but I'm looking for feedback on my spring choice. Relevant data: it's a v6, all a/c removed, battery will be where the rear passenger seat was. I have 2" drop spindles and want the rear down about 2-3 inches too. Muffler will be moved underneath. I expect front fender lip to be 24 1/2 inches give or take and the rear not much higher. So, given my budget, knowledge, research and the above set up I'm thinking of the following. Front: MOOG 5664 trimmed to get the height I want. I believe these are about 750# so maybe a little more with trimming. Rear: Global West S-39 also trimmed to give the desired height. I've been trying to find the rate of the S-39 springs but nothing so far. I eventually found a post somewhere that listed the S-40 spring as 190 #/in constant rate. From what I've read that may be a bit high in relation to the front spring rate so was thinking of S-39 which I assume is lower. But how much. Any additional information, suggestions or alternatives greatly appreciated.

 

Anyone?
