It's a good plan but do it legit or they will reset you at 0.
I'm running bistein 5100's and get decent flex but that is a radius arm issue. The Deaver coils I put on about a year ago are a great improvement over the superlift ones I previously had. For good flex the arms need to be much longer. Duff e-arms in the future for me.What shocks are you running? Do you think that they really help articulation?
