During my first session with DSC off, I spun out and created a 5 figure repair bill.
So, don't turn DSC/MDM off just because the M3Post people tell you to. Ask yourself if you are ready for it and if learning how to drive at a more advanced level is worth totaling your car.
Of course, there are smart ways to mitigate "the ifs in life", such as learning to drive on a skip pad, or driving DSC off on tracks/part of tracks with safe run offs, or just buy track insurance...
...which is what I did.
