There is no way that GTO is stock, and the use of slicks mounted to the stock rear rims and that little purge of nitrous while staging proves it. From what I understand there are a lot of F-cars running that fast or faster on the same ls1 that is in the new GTO, so really the only drawback to the GTO chassis is weight (which is excessive compared to the last F cars). Still, thats a pretty impressive number to run for any car. Cool vid.
