Check out this video featuring Hans Joachim Stuck: http://www.motorsportretro.com/2012/08/audi-90-quattro-imsa/ It brought my pulse rate up a bit -- I was there at Sear Point in 1989 and saw the pair of 90tqs win. The sights and sounds were unforgettable. The video brought back some great memories. Unbelievable that was 23 years ago. -Ti
