Purpose and fitment

The presented item is designed as a rear left door for the BMW E36 sedan, positioned on the side of the vehicle body. The construction is based on factory mounting points, which facilitates the transfer of hinges, locks, wiring harnesses, and other components from the previously installed part.

The door is part of the original BMW body structure, ensuring it maintains proper side rigidity, body lines, and compatibility with factory seals and glass.

Color and paint layer

The component is finished in Cosmosschwarz Metallic - 303, a color characteristic of many BMW E36 models. The metallic paint coating ensures consistency with the manufacturer's original color palette, which in many cases allows for limiting paint work to potential minor local touch-ups.

For users concerned with maintaining the original appearance of the body, color compliance with the factory designation is a significant advantage during restoration or post-accident repairs.

Structural characteristics

The door belongs to the Doors and door panels group, which are components responsible for protecting the side of the cabin and ensuring the proper operation of windows and seals. The panel design allows for the installation of standard internal components, such as upholstery, window regulators, or locks, allowing for the reuse of existing parts from the vehicle.

The original geometry of the edges and body lines facilitates achieving even gaps relative to the fender, rocker panel, and pillar, which is important for both aesthetic and functional reasons (proper closing, sealing, and noise reduction).

Condition and service application

The item is in used condition, making it a sensible choice for maintenance repairs, restorations, and vehicle rebuilding after collisions. Used doors often allow for the preservation of the original BMW body structure at lower costs than new panels.

This type of solution is particularly effective in projects where the combination of correct geometry, color matching, and an optimal repair budget is key.

Integration with other BMW body components
