i am a little bit perplexed on the sway bar and busshing. i am trying to change my rear rubber mounting bushing and the front control arm bushing as well with powerflex. the swaybar bbushings are the problem. do i have to get new swaybars that come with the bushings or i have the alternative of having a good discount on the the stabilizer bar at Bmw gallery and add those bushings from powerflex? any suggestion vis a vis the bmw swaybar or the new sway bar will be greatly appreciated.

thanks,
