Doesn't matter about the track. What matters is if you drive the car right on the edge. Then its always fun. Although I can see your point, Steve. At Lime Rock, for instance, a typical class f/g 911 runs about a 1:03? The track record is 45 seconds in a Toyota GTP car from the 1990's. I can imaging going around the track 15-20 second faster than most DE 911's run. It becomes more work, perhaps, but that type of work
can be fun!
