There are a bunch of pics of the new MBX5R on Neobuggy.net
The MBX5R comes with the longer X5T shocks, servo saver and 4mm steering links. They modified the upper and lower front arms and rear lower arms to accept the longer travel as well as the chassis (you can dremel the old arms and chassis though and they'll work). Has new taller shock towers for the longer shocks.
