Anyone lowered their X6?
 

I'm wondering if anyone has lowered their X6. If you did, which company did you go with and for what wheel size:

Hamann 40mm
H&R 30mm
Hartge 30mm
AC Schitzer 30mm

I'm guessing that the numbers they show is how much it drops, correct? Is one better then the other? I want to put on 22" wheels. Please post pictures of your lowered ride, if possible. Thanks.
