[Call me the breeze]

I've read a bunch of threads on the F30 forum about installing the H&R front and rear sway bar kit on xDrive but I am wondering if anyway had done it on an F34. I understand it's a PITA to install and before committing to this major undertaking wanted to hear from others. The F34 xDrive is top heavy and rides higher than a standard F30 and has a lot of body roll. My 2004 E46 with 17 year old suspension rides flatter. I am currently running Bilstein B6s on stock springs with Michelin PS 4s (nice combo BTW). While better than stock, looking for that planted E46 feel. It's a DD with AutoX in the future.
