Yep. The Bilstein strut has a snap ring that you can put in either of 3 slots.
Stock Height, .5" Lower, and 1.0" Lower.

Sounds cool might have to look into that. My car is dipping down and makes a lot of knocking noise over a rough road
any ideas?

Struts and/or Mounts, check your swaybar links and the rest of the suspension while you're at it.

Can't diagnose a suspension clunk over the internet...
