This part is listed by BMW as BMW part number 31352283123 (31 35 2 283 123) and is described as the 29mm front stabilizer bar / sway bar from the E64 M6 cabrio. When purchased with new bushings and brackets it can also be used as an upgrade on all other RWD E60 5-series and E63 6-series models without Dynamic Drive.
See the Related Items link below for full kit if you are using this as an upgrade on another E60/E63 model (and not an M6 convertible this was made for).
This is a Genuine BMW front sway bar with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
