E55 / E63 owners who race on ROAD COURSES...what is your feedback?
But I could be mistaken, or the source was wrong....
The manual says when you switch off ESP the "ETS will still apply brakes to the spinning wheel" and "the ESP operates while you are braking."

Edmunds IL once said this: "Acceleration Comments: Typical Mercedes traction control meddling despite ESP off."
I also found this review of the E63 on EVO UK and maybe that's what I saw some time ago(?)
"Of course, there’s ESP acting as a silent and almost undetectable guardian angel – isn’t there always in 2006? – but it has an off switch. And although it’ll still cut-in should it think you’ve run out of talent, by then there’s a good chance you’ll have just punted two-tons of Benz through a hedge. Backwards."
"Like an M5, the E63 is a great entertainer should you remove the first layer of ESP."
The ONLY way to completely eliminate the ESP nannies is to run in DYNO mode.
However, you will loose your ABS as well
I tired this in a C32 at Beaverun, and it was NOT the fastest way around.So ESP off, and deal with the nannies in the background, provided that you have some track experience, IMHO.
Have fun out there guys, and be safe

So how do you deal with it on the track if every time you hit the brakes, ESP comes on? If the button is off, does it go back off after you release the brake pedal?

Usually it only comes on when punching the throttle, or trying to go TOO fast around a bend.
Now in the rain, on a hard brake check you could get it to come on, but on try pavement I doubt it.
As far as the ESP button is concerned once you have it off and the little triangle is lit on the dash, it stays OFF until you hit the button again.
IF the ESP does function, read electronic nanny here, while you have it off, then yes it does shut off again after it corrected whatever it didn't like.
Sounds a little confusing I know, but on the track it works well.
Again, I do remind everyone here that IF you are a rookie to road courses, PLEASE leave it ON until you are comfortable at speed and know the track. It doesn't take long for an over zealous driver to find themselves off course and well anything can happen then..

My question was not about the ESP light coming on when hitting the brakes, it was about ESP coming on when hitting the brakes when you've turned ESP off.
You did say "as far as the ESP button is concerned once you have it off and the little triangle is lit on the dash, it stays OFF until you hit the button again." So to answer my question, that means if you've turned it off, and it comes back on when braking, it will then return to no ESP on after braking, right? In other words, it only comes on as you're braking. That was all my question was when I asked: "If the button is off, does it go back to off after you release the brake pedal?"
Anyway, the whole point of this (for me) is that the nannies are there even when the button is turned off; it's not a 100% "nanny off" sort of button.....
