common breakages / upgrades on tm2?
 

Is there any common breakage on TM2 and what upgrades part I must have?

this is for TM2 V2

The team c stuff is pretty strong these days.
Sensible spares would be a set of wishbones, front c hubs, front camber link block, front chassis upper + lower plate, spur gear and some rod ends.

I'm not sure if the V2 uses a different spur but an RW spur would be the only upgrade that's really necessary.

ally c hubs and ally front upper link mount, full set of wishbones, rear gearbox case and ally rear suspension pivot blocks. top and bottom front chassis plates (early one if you can get them, they will allow more steering). front and rear shock towers also.
