Any updates on these? I have Ohlins R&T's in another car and they are great. Although it would seem contradictory, they are firmer AND more comfortable than stock. They seem to just float over the pavement irregularities while maintaining responsiveness.
I'm still searching for my E90 M3, but my first mod will likely be coilovers. If the Ohlins aren't coming out in the near future, I will get some JRZ RS1s. It seems the RS1s are JRZs answer to the Ohlins R&T albeit with a slightly different approach.
