Mondays Racin' with D.O. show is posted on www.Racinwithdo.com.
Danny Drinan was on talking about his Dri-Bar for sprint cars. He explains who it works and where to get it.
Give it a listen.

D.O.

The stuff with Drinan was very good, and yes he did explain it, but I am not sure I comprehended it all. I might have to listen again. Sounds like his equipment is working quite well for some though.
