Well, I do not have anything to hide from the Camaro5 guys! Only see GT-R's, Vette's and Stang's at the track.......Camaro guys need to get to the track in the Mid-Atlantic region.

I will try those preload setting next week at Carolina Motorsports Park!

Does your 5th Gen feel a bit unsettled when you use the gator backs in the corners?

Car is pretty stable even over the FIA gators at VIR! Here are a couple video's of VIR last month. I can say one thing is that I knocked the toe out of the front of the old girl. Best time is a 2:18, that is pretty respectable....



Off course at 15:20......

Thanks! I have older instructions.....but we netted out at the same settings.
