Anybody who has a trophy at an SCCA National Event?

First off, most of the time the VSC/TC on these cars is only actuating the brakes, it very rarely cuts engine output (I don't think I have ever had it cut power on me, just actuate the brakes).

Second, your laying skid marks with VSC/TC off speaks to your threshold braking skills, not what is the fastest way around the track in one of these cars (I'm assuming you don't think you are the fastest person in the world in one of these cars).

Third, the VSC will cut in under steady state cornering conditions if there is a filled crack in the track surface. It doesn't matter how good/smooth you are, this is a fact of the nature of the VSC/TC unit in these cars, not the driver.

Fourth, I can be almost as fast with VSC on or off, the difference is that the VSC doesn't permit certain techniques which I can use to improve my time in certain specific corners (it just gets unhappy with that level of slip angle+gforce, though I think there is a sealed crack there that also messes with it).

Fifth: Turning off VSC/TC also permits me to make choices to save the car that I may not be able to make with it on; too many cooks in the kitchen can just make a bigger mess.
