If one were going to be abusing a VX offroad (highspeed plus low speed rocks), what would be the 10 things in order (opinions) that you think would break?

I ask because in theory these would be the 10 items I would want to beef up first.

Example:

1. Bushings
2. Ball joints
3. Lower control Arms
4. Ring and Pinion
5. Engine Mounts
6. Etc
7. Etc


Opinions??
