Guys, I am having an issue getting the shock lengths correct. I am trying to set my EB48.3 with the Lutz setup. It calls for the front and rear shocks to be 120mm and 134 respectively. I have tried different springs but not matter what I do I can't get the shocks near long enough. They're anywhere from 15-20 mm too short.

When measuring shocks what is the proper method? off the buggy or on?
