Sorry I wasn't totally clear. You should be using Sport mode and running up and down the gears using the paddle shifters. Once you enter the track and get up to speed you'll be in 3rd which is where you'll spend most of your time. In Sport mode the Stinger will hold the gear for a good amount of time but it will up/down shift if it hasn't been shifted in a while or if its trying to save itself from heat etc. I'm sure it will be track dependent but once I learned the car and the track I was driving I found the paddle shifters and random returns to D to really be a non-issue.I left the car in Sport mode and never once touched the pedal shifters, so it was in auto the whole time. The one and only major issue that arose was the track control. When I entered a carousel, sometimes the car would think it was turning over, so it basically killed power. It was like I was fully braking with no response from the throttle.
So you are saying that, when tracking, I should use the shifters? I guess I could get familiar with them on my own time first.
When I drive on the track I turn the traction control off but leave the stability control on. Without a rear LSD (Limited Slip Differential) I can get one rear wheel to spin under certain hard corner exits and that would cause the traction control to kick in and cut power. So far I've never needed or experienced the stability control kicking in so I just leave it on.
When it comes to paddle shifters they are new to me too. I've been driving for 33-years and never had to use them let alone work them on a race track. So it took a bit of practice to learn how to use them but once I got the hang of it it turns out that the amount of time I was actually shifting up and down was pretty minimal. I'm sure with a little more seat time you'll be fine.
