DSC Off!
Yeah I know this is probably common knowledge to most here who track often, but it doesn't hurt to re-state in our shiny new track forum...
Once you're at a comfortable point with your car out on the track, turn off DSC. I just got back from the first day of a two-day BMWCCA HPDE that I ran most of the day (like I've done all my other days) with DSC On. I expected, on my first session with DSC off, that I'd be out of control and all over the place with out all the electronic nannies to keep me going straight. As it would turn out though, my best/fastest/most smooth run ever was the first with DSC off. DSC was actually hurting me tremendously, kicking in and scrubbing speed when it shouldn't have been. I am still shocked at how much better the car drove with me in control as opposed to the nannies

I had a Car Control Clinic organized by my local BMW CCA (Quebec) on Saturday.
Drills consisted of: Circular Wet skid pad, Figure - 8 wet skid pad, slalom and breaking and avoiding exercises. In the afternoon thay set up a mini Auto X circuit. This all done in a safe environment: An asphalted area as large as 16 football fields. All were done with DSC off. And I enjoyed it. Finding the limits the car and the driver have. And losing control a few (too many) times, which was encouraged. Now I feel confident for track days with DSC off. I am signed up for 4 days. 2 in July at Calabogie (Ontario) and 2 in August at Tremblant (Quebec). I have done 2 days at Tremblant last year and I'm afraid to say that I am hooked. |

There was a BMW Club Race running at the same time as the last BMW HPDE, and I thought it was funny that all the cars had big stickers on the dashes reminding them to "TURN OFF DSC!". I guess no matter how much you strip a car down, you can't disable the DSC without hitting the little button each time

Annecdotally, on my last track day...I had DSC on as described above....an E60 M5 stuck to me like glue....
Later in the day with DSC off....gapped him by almost 1/2 a lap...he couldn't touch me. |

Unless it's wet, I always turn off DSC at autox events, but leave it alone for normal driving. At wet autox events I'll generally do half with it on to see where it's kicking in the most, and then do a few runs with it off being extra careful in the areas it was coming on.

im a little late on this but.... YES!! DSC OFF!! my first time on the track i had it on and before the day was over the DSC apparently engaged more than I had expected and my rear rotors/pads were toast before the first day was over. cracked the rear rotors and burned right through the pads... i couldnt figure out why at first because most of the breaking is done in the front. Then i realized it was cause by the DSC engaging while i was accelerating out of turns.... tore them up badddd

That probably has more to do with your car not having LSD, and the computer trying to manage inside wheel spin during cornering. On a car with LSD, DSC will still result in some extra wear on pads and rotors, but it won't be that dramatic.

P.S. (broken record) OEM brakes are crap on the track. (/broken record) The brakes won't even last a day worth of track driving. Thank God for BMW warranty.

This really depends on the track layout. The CSL/ZCP package brakes that are on our ///Ms are actually pretty decent on the track especially when combined with a better pad.

I keep mine off in the dry and sometimes in the wet. In the wet it may be faster with DSC on, but it's more fun with it off

Laidback used to sell those shirts over on the M5Board. He also has a MCoupe (and is part of Mfest), so he is on other forums. He was still selling them early last year, but not sure about how.
Here is the link from M5Board, but doesn't look like any activity in the last year. http://www.m5board.com/vbulletin/sal...-shirts-8.html
