From inside the cabin, with the factory doors attached, the factory mirror location is perfectly balanced and set to an ideal height that allows the average driver a good angle of visibility. This stock mirror location should be the target position for any aftermarket mirror relocation option.

A common relocation point for side mirrors utilizes the door hinges themselves. These are among the least expensive option available and provide a quick method of installation/removal. 

There are however several issues when choosing this location. The immediate issue is location, the top most door hinge positions the mirror lower than the ideal factory mirror location. This could be a bit disorienting and uncomfortable while driving on long trips. Some companies try to elevate the mirror through long attachment stems, but the difference is often still noticeable. In addition the door hinge design is difficult to properly clamp and maintain position, this becomes more problematic during highway speeds, in addition to wind noise and vibration. Overall, this is a quick a simple solution if you’re looking to comply with state regulations, but aren’t overly concerned with side mirror visibility. 

Pros:

• Inexpensive solution
• Quick installation/removal

Cons:

• Poor visibility location
• Unsteady position on highways
• Wind noise
• Vibrations

Windshield pillar relocation solutions do a much better job of positioning the mirror higher and more inline with the factory mirror location. This type of relocation is often apart of a quick-release system with a base bracket that is secured to the windshield pillar frame bolts. The initial installation is fairly straightforward and still provides you with the quick install/removal option of the door hinge system, but relocates the mirror in a more ideal position. 

However, these kits still retain some of the common issues as the door hinge systems when it involves highway speeds. The kits generally produce a high-pitched wind noise that can be dampened a bit. They also tend to vibrate if they utilize a long arm stem design. If you would still like to retain good consistent visibility, while driving on the highways it’s best to choose a slightly more expensive relocation solution that incorporates a solid base and rounded backing, similar to the factory Jeep mirrors. These solutions can sometimes become a permanent year-round option and provide with plastic circular covers for the full factory doors, if you choose to relocate your manual mirrors from the doors to this new location.

Pros:

• Better visibility location 
• Quick installation/removal
• More stable and consistent visibility

Cons:

• Some models can still result in vibrations and wind noise
• Price
• Semi-permanent base attached to the windshield pillar
