see? if i hadn't watched the mustangs spank the camaros at watkins glen a couple weeks ago, i'd have thought the same thing. the stang easily walked away in the straights, and turns.
So full race prepared cars somehow equate to what the stock street cars do when matched up? Go back and watch that vid you posted again, and tell me what happens from the starting line to half way between turns 1 and 2.....
Saying that those race results reflect what you can get out of the "consumer variety" is like me saying mid 80's Honda CRX's are faster than '80's V8 Camaros and Mustangs from the factory just 'cause I used to smoke most of the American Sedan (Stangs and Camaros, in a slightly hotter than "showroom stock" level of prep) field in my ITB class CRX. Heck, there were plenty of days my best lap time was faster than most of ITA and ITS, which was made up of Mazda RX7's, BMW 325i's, 240Z's...
