I have a 2009 535i x-drive. The 'sport package' did not include the sport suspension. I notice a fair amount of body roll in the corners. I had a 2005 X5 with sport suspension. Seems to me there was significantly less roll in my old X5. (Am I just driving faster?)

I have searched Dinan and tirerack for stiffer sway bars for a 2009 E60. (I have heard/read stiffer sway bars are the best first mod to make to improve handling). I can't seem to find anything that is suitable for an X-drive version. Has anyone upgraded a 2009 yet? Any suggestions?

 

I think it's going to be tough finding the sway bars for the XI model.

Anyway, in the H&R website it lists only for the application for the 535i model whereas the 535xi model shows nothing.

Added Note: For 2008 onwards, Active Roll Stabilization is another high-tech improvement, which replaces anti-sway bars with electronically controlled pumps to maintain a level ride under nearly all conditions. But this is only available as a sport package option for the non xi model.

 

The M5 sway bar fits on there quite easily, under 30 minutes. I just refitted my 08 with Bilstiens, new controls arms and the sway bar for the rear. Looking for strut braces for front and rear.
