In theory....

I searched this forum and collected info on sport and snow mode, and made a post about it. The short version is;
(Sport mode)
- sharper throttle response, due to drive-by-wire throttle angle re-map
- heavier steering wheel feel due to less power assist
- more aggressive transmission shift points
I agree . On the track I use the VSC as a safety net because my lines are getting pretty damn good and Im pushing hard on older tires. It saved my *** this last weekend when I exited a corner too hard . If it wasnt on I would have spun like so many people do on track days .

So do you recommend VSC on, Sport mode off for track days? I'm curious...will be at my first one in the F on the 21st.

Also- how are the aerodynamics at high speed? I'll be running the Roval at CA Speedway, you can easily hit 140mph+ on the straight.

Depends on how aggressive you are. If you are overly aggressive, I'd say turn off VSC and use sport mode so you learn the limits of the car, not the limits of what VSC can avoid.

THanks Lobux, that's what I was thinking. Any aero issues to be aware of at high (140+) speed?

SCCAForums ran his F at Fontana on the banking and had no issues with aero. You might want to take a look at his thread - he was also on Hoosier R6's.

VERY interesting thread. What's the 'pedal dance'?

I have left it on for every track day I have had. I agree with Lobux that it may have been better to turn it off the first time because I over drove the car. After my first track day I decided to work on my line and make that the main focus. What you will find is that when your lines are good and you have decent ability to enter the corners smoothly and exit fast you will get faster because you are driving the right line. My lines are pretty good and getting better so I use mine as a safety net ( saved my *** last time from a spin into the dirt). Every instructor I have been out on the track with the first 2 times told me to leave it on. An instructor at IND even told me to leave sport mode off on the more technical tracks because the increase throttle response would cause more wheel spin on corner exit if you dont learn to roll the throttle on. He was actually right, but since I have the PSS on the car I have less corner exit wheel spin ( nothing when new ).

Sounds like you are doing a high speed track. All of the ones I have been on seem much more technical compared to the tracks other have been on. You guys reach speeds of 130-140 where I max at 105-110 . You will kill brakes and I will kill tires

I think it changes the trac control a bit. It is still on but I notice it engages more when is sport - just my opinion.
