[QUOTE=DaveG28;658839]The front shock tower doesn't seem weak per se, just in certain circumstances it gives. As said, replacements are now cheap, though I am not sure the DB02 rear one works, how have they made the output drive work?
The gearbox bottoms and tops on the DB02 optional carbon mouldings are the same as trf502x mate, I bought them for mine and the parts tree is the 502x chassis number and A parts moulded on the tree, the carbon content looks exactly the same too

Far as I know the bottom half of the gearbox is ' tilted' on the DB02 to get the centre shaft at an angle
