Very good writer. I disagree with him on many points... I have never liked it when I read things like "to win" when the person really never did very much in that vain. Ok, he won a ProSolo Championship, in an AWD car in a class that was in it's infancy. But wasn't ever that close in a normal solo event when there wasn't help from launching, or when he was running in ESP.
This is also the person that claimed that my cars were 65% prepped, and that you wouldn't make a stock Evo any faster in SP trim.
He has some good points, but on the whole I think it's more good entertainment than valuable as setup help since I do things very differently and actually win-- a lot.
But I'm not an engineer, so maybe that doesn't count.
