The front kit. Replaces the existing mount point allowing you use standard poly bushings. In the past, you could use the OEM m5 mounts, but they are NLA. Brackets, hardware, grease, and bushings included. Replacement bushings, if you change sway bars, can be purchased from Energy Suspension.

The rear kit. This reinforces the existing mount. You use the bushings that were supplied with the sway bar.

Note that some early 533i chassis, and maybe early 633 Csi chassis use a different mount for the rear bars. These kits are for the later model years that look like this:
