tamiya super champ upgrades : Rear bumper with shock stopper

This is redesigned bumper part for tamiya super champ (will not be compatible with the re-release fighting buggy).
It not only replaces the bumber but acts as a rear shock stopper, which gets rid of the stopper mechanism using the zip tie cable.

It reduces the buggy's way too much positive(+) camber rear setting, will reduce camber setting near to re-release fighting buggy, which will give better display appearance(maybe it's just personal preference^^)
