Well, I finally got to try out the stingray last weekend, and wouldn't you know it, it rained the first half of the day. Thankfully, It dried for the the afternoon and I ran it again.
Car was completely stock: Tires, ride height (its pretty high), alignment, and even tire pressures.
I was pretty rusty since I have only done 3 or 4 events this year. Ran the car in track mode on the race setting (no nannies), and as far as shocks go the MSRCs felt pretty good, the car reacted nicely in quick transitions. I plan to slowly make changes to get more grip/handling over the rest of the season and hopefully the shocks will be able to "keep up".
One very interesting data point, as to the performance of this car, was that I let a very good driver (evolution instructor), that runs a well-prepared AS C5 Z06, take his 3rd of 5 runs in my car, which ended up being his best time by just under 0.1 seconds, in a car he has never driven that is stock in everyway imaginable. Although it doesn't prove anything, I and many others were surprised by that result. It was also very encouraging, since the car will only get faster as improvements are made and as I get to know the car.
Next change will be to lower the ride height using the stock adjustments. After that I will give it an alignment (probably use the settings specified in the manual for track events), and then the big decision on what size wheels and tires, and tire brand.
