Thanks to this, the convertible maintains proper structural rigidity in the closed mode, and the user can comfortably use the vehicle both in city traffic and on the road.

The use of an original design characteristic of the BMW brand allows for maintaining the factory mounting geometry and proper cooperation with other components of the roof folding system.

To ensure the correct selection of the part, it is worth comparing the markings with the vehicle's service documentation or the existing component. The product has assigned part numbers and interchangeable numbers, which facilitates verification of compatibility with a specific car configuration.

Characteristics of the used component

The mechanism comes from the Convertible soft tops and parts category and is a used component, which in practice means the possibility of an economical repair of the roof system while maintaining the original design. Such components are often chosen in situations where the existing mechanism has worn out or been damaged, and the priority is to restore the proper operation of the roof at reasonable costs.

Before installation, it is recommended to perform a standard check of the mechanical condition, inspect the mounting points, and ensure proper alignment relative to other system components, so as to maintain smooth drive operation and even roof locking.
