Ok in the dry, lethal when wet especially when cold, noisey and uncomfortable. Car bounced down country roads tramlining all over the place. I was going to sell the car then fitted Goodyear F1 GS-D3's (non run-flat)what a transformation!!

Have these fitted to my Z4. Now worn out and looking for something else - probably going to try the Continental Sport Contact 3 (if I can get some!)

Generally, these are ok, but not sparkling. They are pretty good in the dry but take on a life of their own in the wet; I find myself having to be really careful! Can't really comment on the progressiveness because the traction control (which I tend to leave on) on the car is pretty good and tends to cut-in and stop any slide before it happens. When they do go though, they go very quickly, but this is probably an unfair assessment at obviously the car has already reached the limits of the traction control, so I suppose it's to be expected.

I don't think I'll fit these again (they were fitted when I bought the car); the wet-weather performance just doesn't cut it, even when being very sensible. They seem to have worn rather quickly too, but I suspect that's my fault :-)
