After my ECU Flash Tune I'm looking to move on to suspension next in my 328i 6MT MSport. I track my car once a month or month and half for a weekend with a HPDE club so I'm looking to work on body lean and high speed stability (floatiness) mainly. The catch is that this is my DD so I don't want to loose a comfortable ride. I'm attracted to the BC Coilover kit as the price is lower but have heard great things about the B16 PSS10 kit.

As far as ride height, lowering the car 1-1.25" or so max would be perfect. I'm not looking to 'slam' it in any way shape or form. While I do track the car I am willing to accept a compromise that is slightly biased in ride quality if I have to give up just a tad in ultimate handling (I enjoy going to the track for fun, not trying to break some ultimate record or win a world championship My main concern is that the BC Racing kit would ride significantly more harsh than stock or the B16 PSS10 set up. My car is leased so I'll be putting 25K miles on this set up at most before I revert back to stock prior to turning the car in.

Since you track your car, go for the Bilsteins. BC's are affordable, comfortable street coilovers. I don't think even they (BC) recommend them for track use.
