Thanks for the ride-along Chuck. It was fun and you're an excellent driver. That didn't help my AT ALL with my obsession with wanting an M5. Mmmm, 400 HP. A beast like that has to be manhandled to make it fast.
Sanford has always been a bit of a tire "equalizer" -- tires don't matter as much as at other sites. That said, I think you could have seen up to a second on fresh 710s or A6s compared to the SSR. I noticed from the right seat that the SSRs got noticeably better in the second half of the run, so that's something to consider and take advantage of.
I also think I would have been about a second faster (maybe more) on my 710s, which were sitting in the garage

So I think your SSRs were a little better than an excellent fresh street tire on that course.
Thanks Mike. That's an interesting comment about Sanford being a tire equalizer, and it sure makes sense given some observations from there such as your outstanding time on street tires and Keith's time in the Crossfire on street tires too and perhaps others also.
Now of course I want to know what about the pavement at Sanford creates this tire equalizer result, LOL...hence I guess the reason someone labeled me as "Tire Nerd".
Re the M5...three things transformed this car's handling on track/auto-x: eliminating the stagger by going to 9.5" rear rims and 275/35's all around, Ground Control camber plates set at -2.4 degrees front camber, and a Dinan rear sway bar. I later added Dinan springs and Konis which helped some too, but the first three were most significant.

BTW, that line through the last set of turns we talked about was difficult for me to force out of myself. My mind was intent on creating what it wanted in that section, so it took some work to get a different result. I was able to go a bit wider on that entry, and I do think it helped. I just have to be careful with transitions with all this weight.
