[Update]
Good track day yesterday with the AZP group
Rear Proxes RR 295/30/19 were still good
Front: Trying the Proxes R888R 265/30/19 for the first time.
I also tried as suggested to lower the PSI hot to 35.

observations
1. The R888R felt the same as as the Yoko ADO8R with similar lap times.

2. While the R888R are rated as 100 tire, and the ADO8R are 180/200 tire, they performed about the same. After one track day the wear is the same.

3. The 35 PSI hot is not producing more grip than 38 hot, and the wear on the side wall is worse. In addition, with 35 hot, the middle of the tire was cooler than the outsides. Comments on this fact are welcomed.

4. Brakes. front are OEMs. I trying to avoid using the brakes. it is unpleasant.

5. Lap times. Best I was able to do after going back to 38 psi hot was 1:38.1 with multiple 1:38 and 1:39 laps. similar to ADO8R. Since i was able to get the R888R for $240 i was fine with that.

6. For now, the Proxes RR 235/35/19, as ugly as it is on 9.5 rim is the fastest setup. with the RR i was immediately into the the low 1:38 with many laps in 1:37.

7. Up above there is a JRZ settings that are now my road driving settings. When I get to the track i set the front on +1 shaft and +2 rear shaft. After lunch i increase shaft +1 on all corners. so front +2 and rear +3 from base. The car felt better and the fastest time, 1:38.1 was at the 4pm session. so this would be my next starting point.
