I was finally able to test Trofeo R at racetrack. Today I lapped around 45 laps and yes, Trofeo R works very well! Tire is sticky and grip excellent. I tried to keep around 2,5 bar hot pressure around the car and after adjustments my M3 started to work with that set-up. I'm not sure if car could have stand even lower pressures but sidewall seemed to show some small bending and I didn't want to go further. Front camber was -3,0 and tyre seems to work well with that.
After session I inspected front tyres. You could find only very moderate wearing even after nearly 50 high speed laps. Trofeo R seems to last significantly longer than previous semislics (Yokohama, Kumho) I have used. A very good feature.
Let's see what happens after more laps but right now definitely +++ for Trofeo R!
