bc coils or function form?

finally modified the CLS, but I need to go lower so I was hoping to find someone around the sf bay area with either bc racing coilovers (extreme drop preferred) or ff type 1 or 2 so i could feel the stiffness and or comfort or if anyone has gone this low or owns bc's, please chime in with thoughts/comments thanks

the rear is tucked in the 2nd pic because of the angle pulling out of my driveway, that's the intended/goal height it will be all the way around
