I know its fairley pricey so I would say it would be out of reach for the average person on a budget. As far as its strengthen properties??? They say it really does help but I've havent read or heard of much research or facts and figures on it.
Most of the big name racer do use it though and including most cup teams, if you got the money I'd say get it, but like I said I really think its out of touch for most of us. Cp
