BMW 3 Series G20 G28 G30 Replacement Mirror Shells for Modified Horn Mirrors

These replacement mirror shells offer a practical solution for BMW 3 Series owners with G20, G28 or G30 models featuring the specific horn-style mirror modification. Designed as a direct fit component, they serve either as a colour refresh for existing trim or as a replacement for damaged original covers. Supplied as a complete set of two pieces, they ensure both left and right mirror housings can be updated uniformly. The product is manufactured from ABS plastic, a material selected for its automotive-grade durability and ability to withstand typical environmental exposure. With dimensions of 32.5mm by 15.5mm by 16.5mm, the shells are tailored to the precise contours of the applicable mirror assemblies, providing an exact match for the original BMW part 51167422719.

Features and Construction

This product is defined by its specific vehicle application and material construction. The shells are not universal accessories but are engineered for a precise fit on the stated BMW models with the correct mirror type. The build focuses on providing a durable external cover that maintains its appearance under normal driving conditions.

Material and Build

The mirror shells are constructed entirely from ABS plastic. This thermoplastic polymer is widely used in automotive exterior trim components due to its favourable properties. ABS offers good impact resistance for minor road debris, maintains dimensional stability across a range of temperatures, and provides a consistent surface for painting or finishing. The bright black colour is integrated into the material or applied as a finish, designed to resist fading from UV exposure. The use of ABS results in a lightweight yet rigid shell that does not add significant mass to the mirror assembly.

Size and Practical Fit

The shells have an external appearance size of 32.5mm in height, 15.5mm in width, and 16.5mm in depth. These compact dimensions are critical for ensuring the replacement parts integrate seamlessly with the vehicle's existing mirror housing and door profile. The size specification confirms this is a cover designed to fit over or replace a specific component, not a complete mirror unit. The product's applicability is strictly limited to BMW 3 Series models with the chassis codes G20, G28, and G30 that have been modified with the horn-style rear-view mirrors, making vehicle compatibility the primary consideration before purchase.

Uses and Placement

The primary function of these shells is to restore or alter the visual appearance of the vehicle's side mirrors. They are a cosmetic and protective component, sitting on the exterior of the car. Their use is straightforward, with no mechanical or electrical functions involved in their installation or operation.

Event or Professional Use

For car enthusiasts attending shows or for vehicles used in professional settings where appearance is prioritised, these shells provide a way to refresh faded or scratched mirror covers. They allow for a uniform, as-new look without the need to replace entire mirror assemblies, which can be more costly and complex. The bright black finish is chosen to align with common factory trim options, supporting a standard or subtly enhanced aesthetic rather than a highly customised one.

Everyday Home Use

For daily drivers, these replacement shells serve a practical repair function. If the original mirror covers become cracked or damaged from accidental impact or environmental wear, this set offers a cost-effective way to restore the mirrors' appearance. The simple replacement process—swapping the cover only—means owners can address cosmetic issues without dealing with the mirror's glass, motor, or heating elements. The durable ABS construction is suited to withstanding typical weather conditions, from sun exposure to road spray.

Benefits and Buying Value

The value of this product lies in its specificity and material suitability. It addresses a narrow but clear need for owners of certain BMW models, providing a component that is often only available as part of a larger, more expensive assembly from the original manufacturer.

Reuse and Low Maintenance

As a replacement cover, this product extends the usable life of the underlying mirror structure. The ABS plastic material requires minimal maintenance; routine car washing is sufficient to keep the shells clean. Their design does not incorporate complex moving parts or electronics, so there is no specific servicing required beyond ensuring they remain securely fitted. This contributes to a low total cost of ownership after the initial purchase and installation.

Why Choose This Product

This product is selected for its exact vehicle application and complete two-piece set. The key differentiator is its stated compatibility with BMW 3 Series G20, G28, and G30 models with the horn mirror modification, a detail essential for correct fitment. The inclusion of both left and right shells in one package ensures colour and finish match, which can be a concern when sourcing individual parts. The use of automotive-grade ABS plastic provides a balance of durability and weight suitable for the application, and the bright black colour offers a standard, versatile finish. It represents a targeted solution for a specific vehicle configuration.
