### Intended use and fitment for BMW F10 / F11
This kit is designed for the front-mounted rearview mirrors in the BMW 5 Series F10 and F11 models. The design is based on factory-installed solutions, ensuring proper fit with the doors, mirror insert, and other housing components.
This adjustment is particularly important during accident repairs or when replacing individual components, when you want to maintain the original mirror geometry, stable mounting and correct operation of the adjustment mechanism.
### Set construction and functional properties
**The black base and mirror covers** create a cohesive, aesthetically pleasing package that complements most BMW F10/F11 body configurations. The neutral color allows for easy integration with factory moldings, seals, and other door components.
Key features of the set:
- **Stable mounting** – the base ensures a rigid mounting of the mirror on the door, which reduces vibrations while driving.
- **Mechanism protection** – covers protect the interior of the mirror from dirt and moisture, which contributes to a longer life of the insert and adjustment drive.
- **Consistent body appearance** – properly selected elements help restore a uniform appearance of the side of the car after mechanical damage.
### Used condition and economic benefits
This **BMW mirror cover and base kit** is sourced from the aftermarket, significantly reducing repair costs compared to purchasing new components. A used component is a wise choice for maintenance repairs when functionality, proper fit, and budget control are priorities.
By choosing second-hand items, you gain:
- **lower cost while maintaining the original design**,
- the ability to quickly replace a damaged base or cover without interfering with the door structure,
- solution consistent with the factory mirror installation concept in the BMW F10/F11.
### Application in repairs and modernization
This kit is suitable for both standard collision repairs and replacing worn mirror mounting components. By preserving the original mounting geometry, existing mirror inserts, turn signals, and electrical systems can be reused, provided they are in working order.
This approach limits the scope of workshop work, shortens the vehicle's downtime, and allows you to focus on precise installation and correct mirror positioning relative to the driver.
