1.9 camber, toe in - 1 degree. Yes, Toyo R888R sneakers. The springs came with the Ohilns.

I also have the R&T, curious to how many clicks you set them to?

In connection with that, do you run square or staggered since that will affect the choice of clicks. Also a matter of taste and driving style of course. I run TrofeoR 265 front and 295 rear with 3-4 clicks in front and 6-7 at the back. I roughly have your alignment too. I've been at 3.2 or so but currently trying out 2.8 to see if I can ease the inner shoulder wear on the front tires. I felt a bit less front end bite with the lower setting but currently waiting to check out shoulder wear as I go. Planning to put on H&R sway bars in a few weeks to see if that will help shoulder wear.

Have you looked at my little DIY project, tire temperature thermal cameras measuring 16 spots over the tire width, live while driving with logging and video overlay with Harry's or Racechrono. Just around $100 a piece.

I had a student with an M4 that has adjustable ride suspension (guessing magnetically controlled - I'm not up on BMW's technology - still new to it) and it was silky smooth over the section and felt very compliant and planted.

My car, with the Ohlins now, feels the same way. It was stuck down, planted and put the power down w/o getting all skittish.
Yeah, the slightly bumpy/jumpy rear end is solved with the R&T, agree 100%. Very noticeable when breaking hard on uneven bumpy surfaces too.
