The wheelbase is pretty good at 300mm but I find 260 - 270mm works best. Also the overall length is 490mm (but that includes a bit to trim I think) my (RC10) crowd pleaser for the MT2 is only 395mm overall and it works great, bumpers dont overhang.
I have tried my Savage body on the MT2, length 440mm and IMHO it looks a little long with its big overhangs.
