I can't believe this thread is still going around in circles like this... There is a big difference between whether having TC/VSC on is faster and whether or not it is safer. In fairness to the OP, he asked if it was faster.
For those just tuning in, here is a summary:
-It is pretty unanimous that, on this car, your times will be faster with TC/VSC off.
-No amount of arguing will ever convince @
Luis_GT that leaving TC or VSC on is safer for regular driving.
I think those two statements pretty well sum up all the pages of this thread so far.
