Back from my 2nd HPDE weekend with these tires. This time I had the car lowered on coilovers and a much better alignment. Wow, it took me a couple of sessions just to get used to how fast the car turned in. Even on the 2nd day I was pushing as hard as I dared and barely sliding the car. OK, a lot of that is due to the new suspension setup, but I am still very impressed with these tires.<br><br>With this setup I was able to corner at a sustained 0.1 to 0.2G higher than last time at the same track with these tires and stock suspension, and also by the same amount compared to a 2008 civic Si, coilovers/camber and Michelin supersports I have driven there in the past.<br><br>I was able to get some rough tire temp data and saw that my rear camber was about right, while the front could have used a little more, so there is yet more grip to be had from these. Once again, the tires did drop off in grip as things got (very) hot. I recorded tread temps over 200F after one session which is too high for a street tire and explains the drop off in performance - air temp was 100F at this time.<br><br>On the street, these continue to stick like glue. If there is such a thing as too much grip, then that describes these tires, since I have not yet felt any slip at all on the street.

This is basically a fun HPDE / Autocross tire for me. I plan to switch to a different set of wheels/tires for daily driving. Last year I used Conti DW and Michelin Supersports for daily, autocross and HPDE use, howevever that was with a different car, so I can't make a direct comparison.

Ride quality is actually pretty reasonable given the extreme nature of this tire. Actually, ride has improved over the oem Dunlop SP Sport 2050 tires, however, some of that may be due to the smaller and lighter wheels. I'm sure a more recent max performance summer tire will ride better, and a gran touring tire better still, but these are quite reasonable for what they are, and not at the level of harshness of a run flat tire.

Noise is deeper and a little louder than oem, but still not bad. It is more noticeable at lower speeds (40-50mph) now. Smooth tarmac is still quiet, but rough tarmac, or concrete is where you will hear them.

OK, now for the performance aspect. So far I have just 2 days on track with these tires, 1 dry and 1 wet. I was very happy with them in both conditions. In the dry, these held up well for a 25 minute session. They did get slightly greasy feeling after a few hot laps, but much less so than the Supersports I last ran at this track and adjusting tire pressures helped dial that out. There is another comment on here saying that the traction is harder to judge for the beginner due to the lack of audible feedback. I did find it hard to judge traction in my first session, however once I had learned to understand the feedback after that first session, I found them to be very communicative and was able to push up to the limit of traction. I'm not a complete beginner, but neither am I that experienced yet. In the wet, they worked well on track and I also drove through some storms on the way home with no aqua planing.

Overall, I am very happy with these tires and would recommend them for anyone who wants an aggressive street tire.
