I've had the back end of my 306 out at 40! It understeered so I had to come off the throttle and the backend just popped out. This was the first time it had happened to me, I did however manage to catch it by jumping on the throttle (maybe too much lol) because it snaked down the road.
I've had the backend out going around a roundabout flat out in the dry (only a little bit).
Had the back end out under breaking into a corner at low speeds.
Had the back step out after coming out of a corner and applying the brakes gently, but it just completely lost it. I blame this on have 3 different types of tyres each with different levels of tread and a rear offside wheel that looked like this " \ " no joke.
Never will I get a 306 again.
