1/4 Run @ Lap 18 - When you warned me this setup would be looser, I was expecting a handful. My expectations was wrong. What was "loose" about the setup during this part of the run was that the slight push off the corner was gone. I liked the way this setup felt better than the previous run. I could drive the car to the bottom of the turn, get on the throttle a little sooner, and really drive it off the corner. I like the "stiffness" of the chassis off the corner!

1/2 Run @ Lap 36 - Mostly the same as the first 1/4 of the run until the RF wear indicator turned yellow at lap 29. Then, it seemed like it picked up a slight push just enough to keep me from breaking 24 second laps for a while... (More on that below.)

End of Run @ Lap 69 - The last 1/2 of the run was really interesting as the chassis changed several times. The RR wear indicator turned yellow on lap 37 and the car got loose acting for a couple of laps. On lap 42, the right side tire indicators turned yellow and the car settled down somewhat, but lap times were a bit inconsistent. It was like it was in some kind of transition stage because around lap 50, the car really stiffened up and I turned some consistently quick laps (especially for 50 laps into the run!) In fact, on both lap 57 and 66, I turned laps in the 23.9's! At the end of the run, the car was still a pleasure to drive, even though the front began sliding through the corners just a tad the last few laps.

Note: All tire temperature readings were taken at about the 1/3 distance mark of the backstretch.

My comments: You must be prophetic! It was amazing to see the car change during the part of the run you wanted to focus on!

The average lap time during the first 1/3 of the run dropped slightly, though a little more consistent. The average lap time during the middle 1/3 of the run again dropped slightly. But, the average lap time during the last 1/3 of the run dropped by 0.265 seconds! That dropped the average lap time over the course of the entire run by 1/10th of a second! All that and virtually the same tire wear... who are you?

The thing I noticed most about the tire temperatures was how they didn't cool off at the end of the run. I guess that explains that good grip I was getting the 1/3 of the run that helped me turn those quick laps. Good job!

Maxing out RPM's at about 7200-7500.

DOWNLOAD THE SETUP

Just remember where we start working on area, you might lose in another.. I this case, the first half.

1/2 run: Where did the push occur? In, middle or out?

69 laps and on: Wow! You were running some pretty quick times at the end of the run! The car's characeristics at the end of the run was due to the wear of the tires. So basically with the RF worn more than the RR, the was unpredictable and when the RR tire worn even as the RF, the stablized.

Observations:

• Tire Temperatures: The tire temperatures are starting to come into the range what I was aiming for. Notice the tire temps on the left side of car doesn't fall off much yet the left rear is a smudge high. As for the right side temps, the RR is a bit low to my liking at the beginning and middle stages of the run. Yet at the end of the run, both right sides were even in temperature! At the end of the run, I usually like to make the RR just a tad hotter than the RF but not so much to throw off the balance of the car.
  
• Tire Wear: The RF wear a bit too early for my liking, so we are going to have to soften this wheel!
  
• Laptimes: They picked up a bit, meaning loss time but we have averaged better then before.

My Goal for this run:

I am trying to get the car a just tad more freer at the latter stages of the run and also change the rate of wear for the RF. This is going to be a big set of adjustments. I hope we'll get that tenth back with these set of adjustments and better tire wear, if not, there's more adjusting. Also, tell me during the run the grooves that the car is comfortable or wants to be in. Don't change your driving style! Let the car tell you. I am thinking at half tank that the car wants to be a 1/2 or 1 car width up on the track.

Setup Adjustments:

• ARB- Increase the RARB bar by one, I would like a bit more grip in the middle of the corners
  
• LF Tire PSI: Increase by 0.50psi/half pound. Why? To stop the looseness in the transtional period where the RF is in the yellow while the RR is little green. This may tighten up the car though at the latter stages of the run.
  
• RF Tire PSI: Drop one pound/1 psi, this will aid the car on entry of the turn at the latter stages. Basically, it's going to be more neutral and hopefully just a bit looser.
  
• RF Shock/Dampener: DECREASE BUMP by two. Why? I am softening up the RF to cure the wear rate. This should also help in the entry of the turns.
  
• Wedge: Take OUT ONE round. This will aid in the middle of the corner.
  
• Rear end Gear: Increase by one. Just wanting better acceleration coming off the corners.
