This was last weekend at the most recent NASA Rocky Mountain track event. The track is in La Junta, CO, at the airport and is 1.5 miles long with 7 turns. I was in HPDE3 with 4 other cars (3 C5 Z06s and an '84 Dodge Charger race car). They all had race tires, but I started out on my 255/40-17 Falken Azeni RT-615 with the intent of putting on my V710s for the 3rd and 4th sessions in the afternoon.

The vid shows us in the 1st session learning the course for the first time. You can see many mistakes and can see how I was really struggling with the street tires, since I am used to racing on my V710s, so I was going too hot into most of the turns. When I pass the Charger, he screwed up and moved to the right instead of the left, so I had to slow down and wait for him to move left and signal before I could pass right. When I catch up to the yellow and silver Vettes, the silver guy also screwed by giving the pit signal instead of the pass signal, so that is why I slowed down there, too. The vid is chopped so that it doesn't show all the boring footage of me by myself, so that's why it jumps at certain places - not perfect editing.
The last lap of the vid was my fastest lap of 58.4s. The fastest lap of the weekend was a 57.4s by a World Speed Challenge SRT-4 (Chronohunter has raced/beaten him here locally), 2nd was an American Iron Z28 that ran 58.0s, then 3rd was the silver Z06 in this vid that I passed but driven by the father of the two in TTU - he dropped down to 57.8 on day 2. I never got to put on my V710s, because I blew out a brake pad that then killed my rotor with deep grooves, so I had to go home. I believe that I could have maybe surpassed the 57.4 by the SRT-4 - there's no guarantee, but it would have been fun trying, especially since I put down that 58.4 on my first session. The SRT-4 only did one session, so it's possible he could have eventually done better, too, had he kept racing.
