First take all the "aluminum" this and thats out of the equation. These are helpful parts, not "needed" parts.
you can get the same degree of perfermance out of the plastics.

Secondly, the plastics themselves. In regards to your Plastics/Carbon/Graphite question:
Each form of part has different characteristics in certain climates/track conditions...
Plastics generally provide more flex, whereas the carbons are stiffer..less flex.
Plastics will hold up better in the cold and likewise the carbon tends to be brittle.
Which also leads me into the RPM comment... Those are aftermarket.
they tend to hold up better than stocks and have that RPM warranty (if your willing to ship them in)..
For the shocks, the V2's are hands down the best improvement on the truck in my opinion.
