YOu better have a pit man that is willing to wear them....

As far as locla raceing I think they are not needed, and even racing at 2 pro series events I didnt see anyone wearing them.

But hey buy them and tell who ever is your pitbeetch they have to wear them.....


P.S. Did you see on rc universe a guy had the advantage CF revo chassis and it split in half ripped threw his radio box and ruptured his battery pack casung his revo to burst into flames on the track.....
