After about 1000 miles or so I'm finding the F1AS2s a little squirmy at high speeds. I only have them on the rear and the inferior Michelins are still on the front, so I'm hoping this is just unbalancing the car a little and nothing more.
Grip, however, is much better, and I'm not suffering any comfort issues. Hopefully once I replace the fronts as well the car will settle down a bit more.
Had the front tyres replaced yesterday (along with one of the nearly new rears after finding a screw in it :/ ) so have F1AS2s all round. Squirmy feeling is now gone and the car feels much better. Front end is much more precise and the tendency to understeer a little is vastly reduced.
Very happy so far...and that's after driving in wet conditions only and before they've bedded in fully!
Still no droning to speak of Fox...although I guess my car suffers from other road noise intrusion anyway.
