Hi Jim, Yes I now understand that the weights you mentioned are for each side. Just having some trouble trying to understand why the chart I used (above) is so completely off. According to that chart I would be using 150 lbs./in. springs.
Perhaps that chart is for stock application on Mustangs which have a lot more wheel travel and much more room in the wheell wells than a Cobra kit.
I just ordered a pair of 275 lb. springs and will likely use those as my starting point and sell the 150s to someone on eBay or?
Thanks, Don
