BimmerWorld Front Sway Bar Reinforcement Plates - E46 323i/325i/328i/330i/M3

A common and over-looked E46 chassis reinforcement is the front sway bar brackets. The studs coming from the frame rail mount can pull through the sheetmetal, causing total bushing mount failure. The likelihood of a failure increases with larger sway bars, race suspensions, and sticky tires that increases the stress forces on mounting points. This set of plates are welded to the underside of the bushing mounts on the frame rail, making the sheetmetal thicker and stronger.

Note: this reinforces the underside of the mount but also check and make sure the mount is not cracking or pulling away from the frame rail.
