I appreciate your comments and suggestions. I would like to mention, though, that when I said "some autocross", I really meant that I'm competing in the Slalom (autocross) cup run by Porsche Club Sweden, and I'm willing to sacrifice a bit of road comfort in order to be more competitive. It's not easy keeping up with the 996 turbos and 987s...
I also have a habit of hunting down 997s on track.
If I'm not misinformed, the BC Racing BR series would let me set the dampers to a softer setting for road use and then a bit harder for the track.
When looking at the cost, it would be about the same as keeping the ROW M030 setup.
