Fun fact, August 11th, 1974 at Mid Ohio one of the entries was a Porsche 906 driven by Horst Petermann of Canada.  If this is considered an entry I will have a second entry in Class D……with a guide that should work on all tracks minus rally tracks 

Indeed the Porsche 906 did race in the Interserie earlier in 1970, so welcome again to another  Brumos RSR "Porsche", I think we would have run your entire collection of "Porsche" cars by the end of the Triple Crown    you could be running a classic Porsche in the Grand Prix
