I would suggest that anyone changing out springs or struts to inspect the dust cover before you tear into it. Its a shame if you have to reinstall a torn boot just cause you don't have one.

Also do some research about front bump stops when buying lowering springs. Bilstein have internal bump stops, koni and stock struts need external bump stops. Koni does not supply them with their yellows. Some have been fine but I had to cut mine at the time of my eibach and koni install. I later tore it apart again to install shorter bump stops, I chose the e36 M3 (same as z3 m) as others have recommended. I wish I would have done some more research before and spared another 3 hours to tear the front suspension apart again.
