Surprised you didn't just plough under steer, I'm guessing you gave it a good flick rather than trying to get through cleanly.
So, with esp off, and white line front and rear swaybars set to hard, medium respectively, round a roundabout enthusiastically in the rain, boy oh boy did things get hairy.
Not sure if I caught it before I ran out of lock or whether the ESP kicked back in as I could hear what sounded liken ABS, but I wasn't touching the brake (was getting back on gas).
Thankfully, nothing happened, just a good fright.

Went in at a sensible speed, gradually sped up, backed off as the front started to slip and whoopsie, the back came around. I was reasonably careful on the throttle lift too. Really surprised me.
I'm pretty sensible on the entry speed to roundabouts. Not a fan of the "lets see if I can turn in at this speed" approach as it usually only ends one way.....
someone mentioned lift off oversteer ?

Yeah I've noticed sean that ESP off only kills the front brake actuated traction control and the throttle cut or timing cut or whatever it is that comes with it. I'll try to log for that. ESP still works in the background at least on my car too. I can feel it when the back gets light. It straightens the car up apparently by braking the inside rear. When my car single wheels at the back end though, something really weird happens. From what I've read, the ECU sees any rear wheel going slow relative to the front wheels as oversteer. So even though I have traction and am railing around a corner, the car straightens up on me - its horrible. It probably first tries to brake the inside rear and when that does nothing (cos its in the air) it chucks a real wobbly.
I've done a bit of driving with the ESP fuse out but not on the track where that particular thing happens to be able to test this out.
I'm really glad that my Polo doesn't have ESP as I think it makes it more predictable on track. It does mean I have less of a safety margin on road which is why I always caution people against setting a rear anti roll bar on hard.
I'm surprised that the car turned around on you with the front bar on hard and the rear on medium, though. Are you running stiffer springs than stock?

just re read my post. Sorry if you are understeering ESP will brake the inside rear to get the nose back into line. Imagine an anchor hanging off that wheel - it'll swing the nose back in. For oversteer it would probably be braking an outside wheel - probably outside front. My bars are on hard:hard but I have softer than stock rear springs.
Got white line front and rear swaybars, AP shocks and springs, poly bushes for the control arms and rear beam. Been playing a bit more in the dry and can definitely feel the front tuck in / rear try and come around, waiting for a rainy day now....

I had a little lift off a little while back too, fortunately at the track and no damage done (although the wall was a little close for comfort) Conditions were wet and I put it down to coming off the throttle mid corner. It happened fairly quickly and didn't react in time. I have fully disabled ESP via vag-com. I doubt it could have saved this moment though.
It's at around 1:08
Apologies for the long video.
