Well Sicco, the arms are not (much) longer, the force wont be any bigger as with the normal arms. The power will be less, because the arms being over the 90 degree angle. It will be translated in a sideways force
I plan on running these arms IN ADDITION to the extended chassis. Should be almost like the LSP for the wheelbase. I can still pull wheelies on loosew dirt with my truck now, so these arms will help a bit I think.
