My guess would be the Jammin' CR buggy mount to fit the mutilator - not sure, but you could match up the center diff bulk part numbers to verify. No doubt that one of our Ofna mounts fits it(either the Jammin' or Hyper - no way the GTP mount works).
I can't speak to the handling, but for general bashing, I am sure it will Git'R'Done just fine. Not as refined as some higher end race machines, though. :)
