Since then my lap times have slowly declined. Mind you, temps have also gone out (less engine power), so it is hard to say. We will see the next time out when temps should again be high, and it will not be a school, so there will be lots of time to drive hard and gather data. If conditions are again similar, and i am slower still, I have my answer.

Pirelli also wants 29-30 hot for pressures. I run a bit higher than that for the rears, but will see how they do with 30 hot. Not sure if the vintage 16 sizes like mine would be the same as with advice for their lower profile versions.

Doesn't Pirelli want 2.2 bar hot (32 psi) for the Trofeo R?
