On a course, maost of the places you can wreck have a gravel shoulder to spin out on. Mountains roads only give you a gaurdrail between you and garanteed death. Take it off on the track and leave it on on the mountains...unless you have a death wish or are a really really really good driver.

road course - off
spirited driving - i turn mine off, but i'm comfortable with that. are you sure you would be comfortable with a 150ft cliff and no VDC?

i thought vdc used a mixture of front and rear brakes to control
body roll, stability etc..-similiar to how esp works on chrysler vehicles
depending on understeer and oversteer conditions the car is exposed to
i know i used vdc on my first two events as Sebring and rear brakes
got super hot, did not use last time and have kept it off during spirited
driving and auto-x

I believe it is the ABLS that cooks the rear brakes.
VDC should be off @ the track. Better yet, disable the yaw sensor to prevent it from kicking in under heavy braking.
Hopefully, you're not driving hard enough on open road for the VDC to kick in...
I used to turn it OFF all the time, untill that bridge thing... Lol

VDC - Off for the track for sure....it will slow you down and screw up your line when it kicks in at will...just at the worst time normally (mid-corner)
However it's your call on the street....but it is wet/gravel/crappy road, you might leave it on

For those that don't know Chris knows first hand the dangers of mountain driving. Hope to see you back at it soon.

The G and Z are heavy cars, and when the back starts to come around, it does so with determination. If you have developed the ability to "steer with your feet" and have "Jackie Chan hands" on the wheel for countersteer, then you will turn it off. If you don't know exactly what the meaning of the above preceding sentence is and how to do it, leave it on.
For an aggressive and experienced driver, it is actually more safe to turn the darn VDC off. For everyone else, it is safer to leave it on.

Same goes for Traction Control System (TCS)? My first track event coming up and I'm thinking so. I only feel it kick in when I'm making right hand turns in spirited street driving, and wicked annoying then.

Note: Even with VDC off, the damned Brake-force-distribution thing kicks in when braking and turning hard at the same time....I plan to pull my "yaw sensor" for the next track day.....as I am literally "smoking" my front pads when I trail brake....I just ran Barber Motorsports Park and had smoke from both from wheels after each session until I stopped trying to brake and turn at the same time. However, I was OK if I just did threshold braking. I started to pull the ABS fuse, but I didn't want to make changes to the car at the track, 3 hours away from home.
I always had this problem, even with stock wheels/tires. However, it is much worse now that I run a "Square wheel/tire" setup.....It is weird, but I don't have ANY issues with this setup on the street even with VDC on.

Correct, no 100 MPH WFO corners on on my way to work... 
Seriously, it is really isn't just braking, it is TURNING and Braking at the same time that make things go crazy.
