I was actually there on Saturday as well. I did the Gold Laps in my SS 1LE and a few of us definitely went more than 60 around the track. There was one cop right after turn 2 my first time around, and then was at the beginning of turn 3 on my second time. I did about 90 through one of the turns and talked to some other guys there that went just as fast and even a little faster.
The show was pretty cool, but I did feel like there wasn't as many cars on Saturday as previous days, and the gold laps are worth the money, but I do wish they would let you go faster without being a rule breaker
