This topic is very amusing to me.I think that the standard shold be 130#/350# as my springs meet the parameters.Does this mean that all those intimidating ABC cars are
going to be slower bearing down on little old me?
I think if it can be proven that the seat pressure is higher than 130#/350# from the factory then that should be the standard for that combo.
Bill,nice comeback.
