I was driving my friend's AP1 S2000 on Toyo RA1 again. We left Savannah, GA on Sunday morning and drove to Jacksonville to play with the Florida folks.

This was my first time on the Whitehouse Naval Air Station runway using R compound tires. My last visit I was driving the G and I was rolling on D1 Star spec street tires. The amount of grip between the concrete and R compound tire is phenomenon! Both Dan and I pulled well over 1.2G consistently on this grippy surface.

Anyway, below is my onboard video and few screenshots of the Racelogic Driftbox data.

The Driftbox is a very useful tool; after the race we can compare our lines and see how we can make up time in certain spot. Also, it allows us to see how our driving style/line affects the car speed and lateral G between runs. It would be great if this device can track throttle opening positing versus time.

There are lots of information hidden in the data, I just have to take my time and see what I can discover :biggthumpup:

This is the course map

With the "replay", we can track the speed vs. time vs. lateral G of runs
