I just came back from my 3rd track day with the M-DCT M3 and I still love the car - this was the first time I tried my new track tire setup and it worked beautifully. The tires are BFGoodrich gForce R1s with 265/35/18 front and 285/30/18 back. This rubber is incredibly sticky and while I got a lot of tire squeal with the PS2's at Infineon and Buttonwillow, it was completely gone with the R1s.
As previously reported by me and others the DCT has a downshift issue under hard braking - My BMW SA is working with BMW NA to figure out what is going on and hopefully it will be fixed soon. Once that is resolved the M3 DCT might very well be the best 4 seater track car ever!!!
Here is the video from a couple of laps at Laguna Seca - in the 3rd or 4th lap you see a yellow Porsche Turbo that had to let me pass

here are also some pics of my track tires and rims:
In case anybody is interested on how thirsty the M3 gets on track:
and for our EU folks:
quite a difference
comparing to the mileage I was getting driving to Laguna:
