NASA Southeast region sent out an e-mail saying they needed instructors for their event at Roebling Road Raceway the weekend after NASA Championships. It's a shortish 7 hour drive over, so I signed up as there was supposed to be 6 cars in TT4. Those 6 cars turned into 5 cars on Saturday and then only 4 cars on Sunday as a Mustang broke on Saturday. I got the win both days without really having to push myself. I set a goal of 18s, and I ran a 1:18.7 on Sunday. Of course I forgot to turn on the camera for that session, but I did get good video of what it is like to start at the back of a NASA TT session and work through the field to get open track to set a laptime as my transponder fuse wasn't working in warmup:

Nice. Robeling is fun, cheap, and fast. But hard as sh*t on tires, esp the front left. Saw your comment on the outside wear and that lines up with that small a tire, that heavy a weight, and the tracks you've been running on for sure. What's more amazing, or funny, is at all these events lately this year the 4 cars are faster then 3's and faster then 2's. So I think you're theory of "crazy aero" in 3 is getting more and more less crazy, time to take the leap >.

Yeah the tire wear I am seeing on both my Hoosiers and my RE71Rs and A052s is a little staggering. I have never raced anything with a competition weight over 3,000 lbs before, and I weighed in over 3,400 after one session at Roebling. I have been using the cold Hoosier pressures that Thai recommended of 28 to 29 psi, but he was on 275 width Hoosiers. Also the Hoosier A7/R7 tire guide recomends not setting cold pressures at lower than weight/100 which would be 33 to 34 psi for my car. They state that going lower than recommended will cause more wear. I also know it is faster, but I might be okay most of the time reducing wear and only running the lower presures when I really need that fast lap for a session. I know the S2k guys on 225s stretched on 17x10s are starting at 20 to 21 psi which is just insane to me. I am going to do some expiementing at NOLA this month, and bring stickers and see if I can help them survive longer.

Edges tell me its camber. It may be time to get a tire probe and have the wife take temps right after a hot lap too. Also do the chalk lines and see how much it's rolling over. Or take a pic with of the tires off the car so we can see, straight down and a couple angles to see how stretched over or under it may be if you want.

did we all just lose 0.2 points

Sounds like it. Despite the fact that no AWD vehicle has dominated the TT4 or ST4 championships they continue to penalize us more heavily then even the ST3-ST1 cars that make more power and can utilize the AWD traction more.
