Great tyres, perfect for a car which gets driven hard and does occasional trackdays.
For road use...
Great on a hot dry road with a bit of heat in, not good in the wet, very poor in the winter. Seriously, I would not recommend you buy them at this time of year, I'm driving like miss daisy atm because frankly I'm terrified of them.
Noise, they are loud, simple. Ride, very unforgiving, even worse than runflats maybe. When I went to these, I had to retune the damping to suit.
If you don't do trackdays, or fast driving, then you would be better off with CSC5 or something.
Track..
Superb, couple of laps warmup and they are on, massive grip and they do not go off. My experience is they feel just the same after 15 laps as they do after 5. Grip level is tangibly less than that of A048 or R888 though, so if you do primarily trackdays then you'd be better off with a tyre like that.
Regarding sizing, don't forget that like all 'S' tyres, these come in cheat sizes i.e. they come up wider than the stated sizes. A 225 section AD08 will not sit happily on a 7J.
