I bet on the street you'd never notice, but on track you definitely will and it really slows you down.

And when you say "unhappy", I assume because you are driving the car to the level where the nannies kick in all the time (as they are supposed to) vs. kicking in because the wheel diameter is off and the car is confused...This is what I am trying to understand - will the wheel diameter change (2" smaller) cause the nannies to misbehave all on its own?


I am driving at the level that my nannies are kicking in a lot (Advanced HPDE run groups, within 1sec lap times when traffic is not a factor). Interesting you mention that it can unbalance the car as I have found it more often is able to save me from when I overdrive the car. The difference is more likely just due to the fact that I have never run with them all the way off because I haven't trusted myself . AND, because I have the SS and it does not have in-between options like the 1LE - mine are either on or off.

I have defaulted to on for stability control and off for traction control because it is safer, if slower. Your "unbalanced" statement is making me question my assumption that I am safer with them on at this point in my driving capability. The fact that I've never been more than 2 wheels off track makes me think I am right, but happy to be corrected by those with more experience than me.
