I was gonna put some kind ov available bolt-on dam on my Challenger, but i've seen so many and handled many more (working with hot rod parts) that i just cant see them holding up at any serious speeds. The plastic in itself is likely strong enough, but that particular area sees a LOT ov stress.

At what speed do the plastic/FG ones become dangerous...??? 120mph? 140mph? 150...???

So far I'm thinking ov a factory looking (not T/A style) piece, a little larger in area, made from aluminum.
