Buying Guide: Key Purchase Considerations
- Mounting method: Clamp-on door-edge mounts offer tool-free installation but require clear door edges. Drip-rail compatibility may limit certain bodies.
- Mirror size and field of view: Larger 4″ mirrors provide wider visibility but may look oversized on compact doors. Smaller 3″ mirrors look subtle but offer less peripheral view.
- Arm design and material: Curved arms and chrome-plated finishes deliver OE-like aesthetics, while straight or stainless-steel arms emphasize durability and a bolder look.
- Finish and corrosion resistance: Chrome and stainless steel resist rust, which is important for exposed exterior use and frequent wash cycles.
- Left vs. right mounting: Reversible clamps offer flexibility for different driver sides and car layouts, useful for twin-mirror configurations.
