Esp
I wanted to ask you guys if anyone thinks this is normal or not.. Everytime i turn ESP off and press with my car after a bit of peeling traction still manages to catch on at a certain point its very annoying why does it do that? My friend's M3 doesn't do that since he has the option of holding on the ESP button for a while which turns off everything.. Does AMG have anything like that?

If you do a search, I'm sure you'll find an answer to your question. In the interest of just getting it out on the table:
You can't completely disable ESP on any Mercedes just by pushing the "ESP Off" button. It's rather mis-labeled, if you ask me. It should say "ESP lite" or "1/2 ESP". Maybe "Almost ESP".
The only way to completely disable ESP is to put the car into "Dyno Mode". Info on that can be found in the above-linked thread (which I just realized was one I started :P ) or via the search function.

what it doesnt do is turn off ASR.
thats what prevents excessive wheelspin.
its possible to spin the car w/ esp disabled (ive done it, nearly went off a cliff)

As we all know, ESP is an umbrella term that includes 2 systems:
1) traction control (or ASR) which limits wheelspin when starting off/accelerating in slippery conditions (it's this system which prevents you from doing burnouts and cuts power sometimes to your drive wheels when you accelerate too quickly)
2) stability control which corrects understeer or oversteer if you corner too fast in slippery conditions
When you press the ESP off button, it disables the ASR traction control to allow for wheelspin when you accelerate. This is most useful when both wheels have zero traction (like in deep snow). With the ASR traction control on, the car can't even move because the traction control cuts power/brakes both drive wheels which have no traction. In this scenario, you press the ESP off button to disable ASR traction control so that you can get some intentional wheelspin, which hopefully will result in some forward momemtum to get you unstuck. (This is listed in the driver's manual and I've had to do this before to get unstuck).
The other thing that happens when you press the ESP off button is set the stability control to a higher threshold before intervening. In other words, it will allow for more understeer/oversteer angle before saving your butt. It does NOT shut down the stability control completely in that it will still activate if you understeer/oversteer too much. This is what frustrates many car magazines because they can't get complete control when oversteering or power sliding the car around a corner on a track when they do their tests.

Here's another aspect that I forgot to mention in my first post. The C55 also has a pseudo electronic LSD system which is still present when you press the ESP off button. (It's actually part of the ASR traction control system except that power won't be cut from the engine). Basically the system will brake one of the drive wheels if it detects excess slipping/spinning compared to the other drive wheel. This is meant to mimic the effect of a mechanical LSD when accelerating out of a corner by braking the drive wheel which is losing traction (the inside wheel typically loses traction and slips when accelerating out of corner) which then results in more power being transferred via the open differential to the outer drive wheel (which has more traction).
This system only applies to the C55 and is not present in the C32 when you press the ESP off button.
