MSW’s Take: We’ve been reinforcing the front anti-roll bar mounts on E46s for a long time, ever since our first race car had a catastrophic mount failure at the track. We decided to offer the same type of reinforcement to everyone in an easy to install plate kit.
The front sway bar mount on the E46 chassis is very weak, and the chances of failure become exponentially greater when you combine stiff anti-roll bars and rough racing conditions. The factory 8mm studs will rip from the frame horns if they are not reinforced properly. The reinforcements included with some bars (such as Hotchkis) do not do a proper job of actually reinforcing this critical area.
These reinforcement plates are precision cut using a water jet. Made from 1/8″ carbon steel. Holes for water drainage were placed in the plate in the same location as BMW designed.
Requires welding, professional installation recommended.
Designed and produced by MSW.
Includes two plates for both mounting locations.
Applications: All E46 and E85/86 Z4 models
