    I always drove mine with dsc fully off (set on M2 button), in the dry, wet and even when icy last winter.

    In the dry and when very wet, the car was pretty planted, it's when the roads are damp that things can be sketchy.

    However I only do that, so that I keep alert when driving, rather than relaxing and thinking the car will save me.

    Doesn't help you I know, but main thing is you are ok the car sounds like it's fixable.

    Yes I do but always when those tyres have warmed up a bit. I'm running Cup2's on the front and MPS4's on the rears. Traction and turn-in are excellent. The car feels really pointy. I always go into M2 after about 10-15 mins. M2 for me is: MDM on, engine is sport plus, suspension in sport, gearbox manual and in the middle setting and steering in the lightest setting.

    Glad you're ok, just get it fixed and move on, check your geometry, read below.

    I had a massive 90mph spin on a dry M42 coming off the M45 very early one Monday morning. I accelerated down the slip, went into the 3rd lane, travelling forward, just touched the rumble strip, made a slight correction, (a lot of experience at the Ring). Then the car just lost traction and started to spin. I tried my best to rectify it but you've got no chance at 90. The motorway was clear and I didn't hit a thing. Funnily I didn't poo my pants but man I was lucky as a lorry drove past me whilst spinning.

    I'd just bought the M3 F80, it turned out to have a bent NS shock and the rear camber was way off with little tyre contact. I put it down to this i.e. dangerous geometry as to why it snapped and not my driving or correction.

    All got fixed & set up at Centregravity and it drives like a different car.
    I lost a lot of confidence in the car, but have driven it quite a lot now and I feel confident as ever now.

    I had my car set-up at Center Gravity in Atherstone when I had the 763M's fitted. Expensive geo at £340 but I absolutely could feel a difference. They take you out for a test drive before and after as part of the package. Maybe it's why I have confidence to push in MDM??

    For sure, it does make a big difference, they've done 3 cars for me so far, RS4 B7 Saloon, E36 M3 and F80 M3.

    agree with people on here when its wet MDM doesn't work that well in the F8X cars. it was fine in my previous e92 m3 (although still had to be careful with the aggressive DCT gear changes)

    either leave traction on or fully off (if you know what are are doing and are used to it). if its really wet / raining just leave it on.

    i think my old PS4S were better than my current PSS in the wet also.

    My view - at least with my driving abilities in mind - is that MDM + MPSS in anything other than warm dry conditions is just not worth risking. I am looking forward to getting MPS4Ss on as I sense they cope with damp conditions and lower temps far better... I think this is probably more about the tyres than MDM as physics quickly take over, I mean what do you think full DSC etc could have done differently to stop you losing it? Main thing is you're OK and your car is repairable - thanks for sharing though as it is a good wake up call to those of us who think we are better drivers than we are (not saying that applies to you) as roads get colder and damper...

    I can safely say MDM does sweet F/A in the V10 after booting it on a dry stretch and the rear wheels lighting up with a bit of arse wiggling action I came to the conclusion TC has a good role to play in me not killing myself.

    I never have the traction on, off or MDM no matter what the weather, what I have found it that super sports get very slippery once below 4mm of tread. Hope you get sorted as painlessly as possible.

    This was in third gear too and from lowish revs, 2.5k ish. I've never had the car step out in third before especially now that it runs the latest engine software with the smoother delivery. We've all probably provoked a slide before but when it happens and you have no prior warning then it gets bad very quickly because your not one step ahead!

    Difficult to say but not enough to do this or so I thought. Maybe just applied it a tad early when I still had some lock on.

    Not sure that keeping your foot in...is a recommended course of action for a rwd car when rear traction is lost.
    Anyway a switch to MPS4s on the rear will definitely improve rear grip in cold wet conditions which MPSSs don't really like at all.

    Sorry to hear this for sure.
    You said it was damp? From those photos, in my world that's proper wet! As well as cold, with nice slippery leaves & PSS, all combining a recipe for such a spin.

    If you get opposite lock correct you can use gas to straighten the car.

    If you come off the gas too quick you could induce lift-off oversteer.

    So yes he does have a point.

    Revs are your friend when driving a torquey motor.
    Low revs and a high gear can spin the rear wheels up in the blink of an eye.

    IIUC...
    Sure you don't really want to jump off the throttle but keeping your foot fully in will generally be far worse.
    In a throttle induced loss of rear grip in a RWD car you have to remove the cause of the loss of grip and relax your foot on the throttle at the same time as applying opposite lock.
    Keeping a little throttle applied maintains some load on the rear tyres and reduces the tendency to lift off oversteer.
