Bilstein, HR or KW???

hi, I have a 996 c2 cabrio with techart springs and serial dampers. (facelift) driving behaviour is moderate, a weing indirect and too little feedback. front too soft and rear too hard. can anyone give me a tip which winch suspension promises a homogeneous driving behaviour and a not too hard setup? so which of the manufacturers can you recommend? pro and contra? would still have the option of special production, according to request. btw. should I also change the stabis? what do you think? of which???
