Purpose and Fitment for BMW Z4 E89

The presented rear left side panel for BMW Z4 E89 is a body part mounted on the rear driver's side. Its construction matches the factory quarter panel profile, allowing for precise restoration of the original body geometry, maintaining panel gaps, and ensuring correct fender alignment with the door and bumper.

As part of the front fenders category in the catalog, this component is assigned to the BMW body system and works with factory mounting points and joining technology used in the Z4 E89 model. This enables the body shop to perform repairs according to the manufacturer's procedures, without the need for vehicle structure modifications.

Technical Specifications and Mineral Grau Metallic B39 Color

The panel is manufactured using BMW's specified technology for the Z4 E89 body, which translates to dimensional stability and appropriate rigidity for the side of the car. The part is prepared for further bodywork and painting – it can be used in partial repairs as well as larger reconstruction projects.

A significant advantage is the original Mineral Grau Metallic B39 color. For many repair projects, this means the possibility of limiting the scope of painting, easier shade matching, and maintaining visual consistency with other body panels. The metallic paint structure is consistent with BMW's factory specifications, which facilitates the painter's work when blending adjacent panels.

Condition, Origin, and Application in Repairs

The part is from a disassembly and is offered as a used BMW body panel. This type of part is particularly valued in accident repairs, where maintaining factory geometry and proper body structure function is crucial. The original side panel allows for:

• restoration of factory body lines without the need for fitting aftermarket parts,
• maintaining structural rigidity in the rear of the vehicle,
• limiting the scope of painting work due to color compatibility with Mineral Grau Metallic B39 paint.

A used panel is a good choice for repairs where a combination of OEM quality and controlled service costs is important, especially for sports cars like the BMW Z4 E89.

Benefits of Using an Original Side Panel

Choosing the original rear left fender for BMW Z4 E89 offers a range of practical benefits for the workshop and the vehicle owner:

• Factory Fitment – the panel is designed precisely for this model, with no compromises in fit.
