Losi rear diff - 10t in truggy and 13t in buggy. why?

I believe the different pinion size is to change the gear ratio to compensate for the larger tires

+1. You could run a Buggy pinion in your diff (IDK if you need to change the diff case or not, never tried it) and it would give you a taller gear ratio but you would have change out the pinion gear to get the ratio right.
