E46 HIGH ADJUSTMENT UPPER STRUT MOUNT REINFORCEMENT PLATE

The E46 front strut towers are notoriously weak. For this reason, BMW offered an upper strut mount reinforcement plate from the factory as "the poor road package" (part number 51717036781). The plate adds another layer of 11 gauge metal to reinforce the strut mounting point on the chassis. This is mandatory if you have an aftermarket performance suspension setup on your E46. Stiff suspension + strut bar can lead to cracked strut tower housings on the E46. These reinforcement plates can help you prevent expensive damage. Blown shocks and stiff suspensions will cause the sheet metal to pop up due to more energy being transferred. Highly recommended upgrade to drastically reduce "mushrooming" and other strut tower deformation. Installation is simple. These just fit from under your strut mount and are installed between the top hat/camber plate and the strut tower.

This high adjustment version by Garagistic does not have a smaller main hole like the factory BMW reinforcement plate so it does not get in the way of camber adjustment and still provides all of the same benefits as the OEM plates!

We recommend always using a little blue Loctite to make sure the bolts don't get loose! This is the version we recommend: https://amzn.to/3MWIUlO
