well i see the red racing turnbuckles looks like a hard crash broke the front two and they put stock back on. Just like i said
alumin a arms
steel cvs joints
Some type of metal rool hoop
wide front rpm bumper
tuned pipe
looks like a upgraded servo

Those appear to be all the upgrades

Also some people have trouble with the top plate breaking they make a brace to stop that. Thou i have never experianced mine break yet. Also i would say go on ebay and buy a extra screw set. Another thing get a flat pack witch most likely you alread have i would bet.

Another thing clean your air filter and i keep a couple extra on hand. It looks dirty
