After being bored for hours on Sunday i read Jegs cover to cover and saw spring seat shims. BAsically it looks as if you stick a shim under the lower spring seat to give more pressure. Now if you are only running a cam (itr for instance) that dont have a crazy lift can you use them to gain pressure. Im not sure how much lift that most springs can take but i would bet that its well over what we run. Anyone try it?
