not being funy, but surely the obvious one is to have two sets of dimensions, one for saddle and one for stick packs, as obviously you need to govern size, so manufacturers have size guidelines to manufacture chassis to.
I mean, you could say about adding length to accomodate saddles length wise, but then what about the 4wd cars that can't accept that overal length and cells are then made longer, you go from alienating one style chassis design to alienating another.
One size for Stick
One size for a Saddle
