Sustained 1.6 G lateral grip is in the range of a cup car on slicks. I can't see a 991 GT3 on SC2 or Trofeo R getting close to that, except transiently. Check this out, keeping in mind significant camber of nearly all of the turns:
Weird to see rear tires wearing faster than fronts. Maybe something not right with alignment?

The mayor had his car aligned at a different shop than me and we are both seeing the same wear patterns. The extreme heat might have something to do with it...

brake feel was good, endless brake fluid
do order posted his pedal went to floor. he and I run same MC and front calipers. I'm on pfc08. so I think it's down to fluid.

You guys are studs hammering around that track in 113F heat!!! It was hard enough the w/e before at 101F and limited driving time compared to the open session you had. I hope you had several beers at lunch time to keep you well hydrated?

In regards to the difference in lateral Gs, it probably has something to do with differences in calibration. Internal accelerometer vs GPS calculated Gs. Plus with the solo you need to re-calibrate every time you change mounting position. I can see the trofeo R getting 1.4G in ideal conditions with my accelerometer. It gets 1.3 in extreme heat...

Kyrocks. The inbuilt display is transient I suspect. My AIM DL & Vbox do not correlate with it after a day at the track. The inbuilt display is always alot higher....

With SC2 and -2.0 cambers, my readout shows 1.60 Left, 1.73 Right, and 1.48 Braking. But with those being peak values, I don't place much value in them. Hitting curbs, etc. can generate fairly high transient peaks.

For sure. In that vid I posted, compare the lateral G in T9 (which lacks camber) versus the other turns.

I freshly calibrate the G-sensor in the AIM Smartycam HD 2.0 every time I mount it to the cage. Like yours it then gives me an accurate overlay on the video feed. I see 1.1-1.2 with a max of 1.3 sustained on a warm day. We have a corkscrew and a lot of elevation on the track. My Porsche dash G-meter often reads 1.68 peak after an hard sessions. dont think Ive had it beyond 1.70 but I dont bounce of teh chicanes much...
