who's using one and do you think its worth the effort to install one

reason im asking is i have one around. right now im running 50/50s, solid LCA/UCA and slightly stiffer then stock rears

would the pinion snubber be benifical?

yesterday with this setup minus the stiffer springs and using B springs i put the right wheel way up in the wheel well and bottomed out on a 6400 launched and it caused to car not to 60' as it should of
