Just picked up a 2010 E60 (535i) and am going to install the KW Street Comfort CO kit. I noticed a post that indicated you have had them installed on your car before (currently?). Sounded like you were running 19" wheels with an offset of 20 in the front, pretty much exactly what I've been considering. 245/35/19 front and 285/30/19 rear. Any rubbing issues? Need spacers?
Overall thoughts on the KW? How was the comfort of them? Mine is going to be a daily driver, but am also interested in good handling and and minimal body roll. I've also picked up a set of RDSport adjustable sway bars, did you have stock sways on or upgraded? I've heard mixed opinions about running sway bars and coils, some people say adding sways are unnecessary since body roll is so well minimized by coils....thoughts?
