I have decided to go with bilstein b8 struts and eibach pro kit springs. Does anyone know if I am going to need different sway bar end links?

Is there any contention to this decision? I'm afraid my ride quality may suffer from lowering the vehicle but if it's negligible I'll go forward.

Edit: after consulting a friend with vastly more knowledge than I posses, I have decided to go with these midrange coilovers for a number of reasons.

1. They are specifically designed for awd e92 application.
2. They are fully adjustable including ride height, camber, etc.
3. I believe that the lowering springs and shocks combo with compromise the ride quality.

While lowering the vehicle is an added bonus, ride qualuty is paramount for me and my area.
