Ground-Control should have their line of parts up for the S550 in the next couple of weeks. For anyone that isn't familiar with them they are very popular with the autocross and road-racing groups for making great basic and complete coil-over kits. They are big on Koni's and I'm sure that had something to do with their delay in releasing bits.
I have run their basic and complete coil-over kits on several of my M3's over the years and they are great and GC has great customer service. I was able to specify what spring rates I wanted with my kit and also buy extra springs of different rates in order to swap out for HPDE weekends and daily driving duty.
