Hi guys, couple of us are heading to RA later this year for a regional and then the ARRC. I have 2 diffs for my car for different top speeds. Can someone tell me what kind of top speeds a good ITS car will hit at Road Atlanta. Thanks for the help
 
Some of the alternate rear gears may be better on the back straight but you will get killed out of 7 and uphill into 1. Go with the 5.12. Don't have telemetry from RA to give you speed numbers. Seems like 125-128 rings a bell.
 
The last time I was there was in a street Porsche 996. 3,000# w/300hp. About 130 braking into T10 if you launch well, FWIW.
