It comes with the bushings already mounted on the bar. You reuse your existing bolts and endlinks.
The install is a breeze. Once the underbelly pan is off there's only 6 bolts to remove the bar. You can do it easily yourself on ramps or let your shop do it. They should not take more then 20-30mins tops.
I have ACS springs now, my 535i still sways more than I like. Great to hear the bar solves most of it.
The M5 I test drove was very flat.
