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.
