I think you'll find that almost everyone turns it off for track use (assuming I remember to). In my car the car, with an SC, it just feels more unstable under hard throttle when traction control is trying to compensate for my right foot. Without the TCS everything just feels better.
It has also been suggested several times that leaving the TCS on will increase rear pad wear.

TCS is fas too intrusive for track use. I run the 1/4 mile and TCS will demolish any chance of a quick pass. I would imagine its the same on a road course.
TCS uses the rear brakes and cuts engine power if it's turned on and gets activated.
I try to remember to turn my car's TCS off every single time I start it up, just on principle. I hate the thought of anybody else's programming - which amounts to the way that they want me to drive - taking over even this little bit of control of my car. They aren't driving it.
Yes, off. You should drive the car...not the computer. I laugh at guys with the latest Evos, STIs and M3s with all their electronic gizmos, pretty poor way to learn how to handle a car.

My brother told me someone at a Mosport Porsche club event with a new 911 was having trouble with the PSM. It started working again but then failed as he was entering turn 8, which I enter about 70 mph. He was OK but the car was write off!

I suppose you can call it 'help' under some situations. But it's a double-edged sword. Do not trust it blindly.
It can also get you into deeper trouble if it lets you get going to a higher speed under poor conditions than you could do all by yourself with no such help. TCS will not make the brakes work any better, or give you increased cornering grip, and once you get going those capabilities will matter a lot more than the ability to accelerate. Think snow/slush/etc. here.
If it teaches you to rely on it, as it eventually will if you always leave it on, you'll likely be in worse shape if it goes MIA as you will never have learned what the car's limits are or how it behaves under extreme conditions.
I often forget to turn mine off, so I wired in a relay so that the switch defaults to OFF rather than ON. Works great and I only have to turn it on when I drive in the rain. I got the mod off another forum and I don't have a link available.
