I have looked through the logs although I am 1.3 seconds off the pace, 1.1 second is lost in turn 2 in QR where I had my incident on the previous track day! So, I am actually quite close to my PB. Other sections some I had better times and some I haven't, so that I put down to my poor technique. So, in summary - if you are able to manage the heat in these tyres it is going to last a long time. My thread depth has hardly changed at all with close to 10000km of street driving now and it supposed to only have a thread rating of 60. So in summary I think it is a very good dual street/track tyre - the limitation is it rubs and it picks up rocks everywhere for daily use. On track it was a bit of a pain, but as most of my days run with 6-7 flying laps so pressure doesn't make a big deal. However, I would suggest a higher starting temp than I did which was 27 and I was bleeding more and more air out with worse times. The best lap seems to come towards the end of the session so that makes me think I might have the temp too low. So, I would probably aim to run at 33-34psi hot - as the 911 runs around 31psi optimal and our car we should be able to run it a bit higher. Temp did measure quite well though so probably it do take a bit of time for the heat built up to its optimal. Best time of my second track day comes on my 11th flying lap on the 1st session. If you are going to use it as just a track tyre I think there are probably better and cheaper options, but may be still the best tyre if you are going to drive to the track. If you are using it as a daily/track tyre, I think it is quite brilliant provided you are not going to be silly in the wet. I have just had a first go on the Yokohama AD08R and I am actually much happier with this tyre on the road - doesn't pickup crap and it DOESN'T rub. However, I think it feels slower than the Pirellis but hard to compare when a) I am not that experience, b) I was on a different track.
