As soon as you put anything other then OEM on your vehicle, your compromising. I have the Eibech/KYB combo lowering system on my MZ3 and don't like them very much. Before that I had Teins. Didn't like them very much either. Each person on here is going to tell you something different. Be prepared that once you mod your vehicle, nosies and issues may/can happen. If you are the type of person that nosies bug you and maybe even having to take you vehicle apart a few time to trouble shoot the issue, then DONT mod your car.
