I pushed the car hard in six 20 minute sessions and the tires held up nicely, though slid more than my past time out (I suspect the lower temps contributed to this). I still think 36 hot is the sweet spot for this set up and I'm still happy with the tires. I have about 180 miles of track time, plus about 3k miles of street miles on them and they are holding up pretty well. I'll try to post some pics.

I used the R-S3s on my 14' 235i with lots of success. I ran a square setup with a 17' wheel all around with 245-40-17 R-S3s. I am hoping to use the R-S4s this coming season on my M2.
