I can't imagine those parts breaking as part of "normal" wear and tear.

If you're jumping a lot and/or hitting stuff you'll break things.

I thought I was safe at the track instead of driving around the neighborhood, boy was I wrong. Run it fast and hit a jump wrong...go end over end... you'll more than likely break stuff.


The key is to make sure that stuff you'll likely break is stock, plentiful, and cheap.
