The MO3L or MO3M are the best kits to get. Both can be made into a short by removing the spacer. If you get the MO3L this can be made into a M by purchasing Tamiya F parts which come with the spacer, front and rear hubs as well as the C hubs. This is Tamiya PNo 51238.
The MO3R can be assembled as any of the wheel bases, due to the inclusion of the M and L extensions. The MO3R comes with all of the hopups, except for a ball diff and the shocks are brittle. If you have the money, these are great kits, however the standard kit with the ball diff and super mini CVA's are just as good.
The short wheel base,(210mm) has the option of more after market shells, than the medium(M 225mm ) and the Long(L 240mm). Some say the MO3L is more stable, less twitchy to drive than the short, but this comes back to car setup.
At the end of the day,the choice is yours. The M or L would be the pick.
