I personally severely dislike the wet traction of the DWS. My daugther's car had them and my 4.8 came with them. They were horrible. Rubber is too hard to have any grip. I ended up going with Michelin Pilot Sport 4S on my 4.8. But I also have the Conti Extremecontact DW on my e38. In my opinion both are superior to the DSW. But I do also have to run separate winter wheel/tire combos.
