Never been happy with the lack of traction (under power) around the corners no issues. Fitted with Michelins at the moment, do the Conti's fair any better, or is this just the M3 way...
Pilot Super Sports. The best road tyre out there in my opinion. Had them on a variety of M cars and just put them on my C63. Amazing tyres. I think they are standard fit for the new shape M3, so you probably already have them.
