This. I kept DSC on in my 330 until it got in the way. It did save me a couple of times...I knew I screwed up and didn't have to spin the car to know it. More importantly, cars behind me didn't have to know I screwed up as I spin on the track.
I'm at the point where it really gets in the way. Most times, I forget to turn it off until it intervenes. I don't think the intervention is ever subtle...you can always feel it. Not sure about MDM but it has let me get quite sideways 3 times. Once at the 'ring and twice on a slippery bridge near my house.
