traction control question...
maybe a dumb question but i was wondering what the if someone could tell me exactly what the difference between the traction control off and the competitive driving mode is? it feels the same. maybe just haven't run it hard enough...

There are two systems using the TC switch - Traction Control and Active Handling.
Traction control is just that - uses the ABS and adjusts engine output as needed to keep the rear wheels from spinning.
Active Handling is stability control. It uses ABS and adjusts engine output to keep the car pointing in the direction you wish to drive. To do this is uses yaw sensors and your steering input to determine when the car is not moving in the direction you want.
Competitive driving mode basically turns TC off, while leaving AH on.

There is no in-between mode with Traction Control, it's either on or off. Active Handling can be on, off or in Competetive Mode.

There are four domains your car's AH/TC can be in. Not two, not three, not five, but four. Here they are:
1. "Default". This is traction control ON, active handling ON.
2. "Traction Control OFF". (The active handling is still on)
3. "Competition Mode". (Traction Control OFF, Active Handling reduced).
4. "TC OFF/ AH OFF" (press and hold five seconds) Not too smart for most, IMHO.

Not unless you want to hit a wall, or another car. Go to competition mode. Leave AH on, at least partially. This will not reduce your time, but will help prevent an accident should disaster strike. What kind of disaster could possibly happen? How about hitting a slick spot, a spill of oil or another substance, or simply getting too wiggly on a 2-3 shift.

Doesn't matter about the tranny - there's more than enough torque with either to swap ends pretty quickly if coniditions are right.
And AH isn't a cure-all either. It's amazing, but it isn't foolproof.

Read this thread. This guy did have AH on, but nonetheless, it will serve as a reminder that while usually safe, things can go wrong at the strip.
