As the title suggests.. these are a couple things I've been researching for a bit. Do you guys mostly shut off your Traction Control Systems and turn off your Overdrive? I know people have said before they race they shut off both, and some shut off the TCS before they even put it in gear. In my opinion, the few times I've actually punched it I've never actually been bogged down by the TCS like I used to in my '04. Either the factory Pirelli's are really good or they did traction control better this time around. I also have an automatic so I have my worries about shifting into Overdrive if I'm at the track or for some reason hit fifth on the street/highway. Will I even notice a difference if I turn either off?
