I can guarantee you if there was something there EVERY Comp car and PS team out there would be doing it. We work with one of the most prominent head porters in the country on our stuff and he does a LOT of comp stuff. He said they tried it years ago and it was worth nothing. I tend to believe him more than the internets. Having spent alot of time around top comp teams and very good friends with a person who has built some of the fastest comp stuff out there I can tell you without a doubt its not used by the top teams.

I would not be surprised that BES offers it. Possibly to appease those who insist. We race with alot of folks who run BES stuff and none of them use it
