I can add some road experience to this now as well as my Nurburgring experience.
Same tyres, multiple heat cycles through them now, probably about 4000 miles on them total since fitted. Loads of tread still.
Dry road use - no need for warm up, loads of grip right off the driveway, even on these colder mornings recently.
In the wet - I have to drive a little slower. Can definately feel they don't have as much grip, but they are still totally drivable, even in heavy rain with some (shallow) standing water. I wouldn't want to hit a large puddle or a lot of painted lines or anything, but they are way way better in the wet than I was expecting.
For that kind of performance on the road - especially with British weather and temps - plus the performance they gave me on the ring, I would absolutely recommend them. Just my experiences though, with 290hp (fly).
