I had the continentals on my Megane, 1 track day and 4000 miles later they were completely bald. I replaced them with F1's, so far so good. The grip levels are just as good and they don't seem to wear any where near as much.
I had the Michelins on my old Z3, they were fine in dry weather but I found them a bit hairy in damp or wet conditions. When I replace the tyres on my Z4 it will be with F1's without any doubt. Great tyre.
