I am ordering my 320i mounts and enforcer tomorrow from Turner, they carry RD Sway bars. It looks like I have the choice between Eibach, RD, and Dinan. Eibach and Dinan look to cost about the same (450ish), and RD's look to be about 350-400. I figured since I am putting on new suspencion this is the time to do sway bars as well. But I dont know which brand to buy. Any advice anyone?
