This one is always fun to watch.
It's from the vantage of a vintage (cough cough) bimmer whose driver is trying to get past Ken's 'vair and make it stick.
Heres another video, inside the Yenko Stinger at Road America. Yenko only made about 100 of these, and something like 78? are still around. Three different stages, mild street car to full blown racer.
