Ride quality did not suffer at all IMO. Drove around all day and could not be happier with it.
The M5 part # is 31352284460
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.
