Getting to know my E39 M5 a little better now , as I'm in my 6th week of ownership, especially the DSC ! On a spirited drive I've found you can almost get away without the DSC light flashing at you IF your smooth and progressive NOT twitchy or aggressive with steering input and accelleration. Its my guess that BMW programmed it this way, cos its smoothness that gets a quick lap on any track..slow in ..proggressive mid corner and quick out. On my track days I've always strived to be smooth rather than aggressive. If you sit in with a racing instructor you'll find hes twice as quick as you but you wouldnt notice it from the passenger seat....some people think if you get the DSC flashing your driving like a driving God....not so IMO. So a great piece of kit IMO...........What are all your thoughts on this DSC thing !
