Thanks again, Bruce, for an awesome car.
The Timezone Gran Prix is located in La Center, Washington and was host to the 2010 ROAR Carpet Nationals. It's a large track with about 5 year old ozite.
We arrived at the TZGP on Thursday morning to shake things in and start testing. The only other time I have ran 17.5 NB was at Carpet Nationals, I spent the entire day just running packs and trying different rollout to timing adjustments until I found a few good options that each had their advantages on different parts of the track. I ended up settling on a ratio that allowed me to carry the most speed 3/4 down the straight and also high speed through the wine-glass section in the middle of the track.
Late Thursday I felt the car had a good enough setup on it to run it until the grip came in more; on the club race Thursday night we were already setting fastest laps in the group much to the chagrin of a few of the CRC faithful in the house. Grouped in with the stock cars I ended up finishing around 6 seconds ahead of the next fastest car.
Late Friday as grip came in I realized the car was just getting better with minimal adjustment. I made some changes to smooth out the car like a little more dampening in the side tubes, and thicker center shock oil.
In qualifying the car was just excellent and carried more corner speed than any other car on the track, it was the dominant car in the corner. Nobody came close to carrying as much speed and I set a early TQ that lasted the day... Other than changing springs in round 3 of qualifying I didn't touch my front end all weekend.
