OE Match replacement door mirror base rubber gasket designed to fit under the base of the door mirror on classic Porsche 911 models built between 1965 and 1973. It sits between the mirror mounting flange and the door skin to provide a secure seal and finished appearance.
Rubber base gasket for door mirror part no 90173111102 or 90173111100
Fits:
Porsche 911/912 1965 - 1973

The base gasket performs two essential functions: it seals the interface between the mirror base and the door panel, preventing water and wind noise from entering the cabin; and it protects the painted door surface from abrasion and stress caused by mirror mounting hardware and vibration.
On older vehicles, the original gaskets often become brittle, compressed, split, or missing entirely due to age and environmental exposure. A compromised gasket can allow water ingress, cause paint deterioration at the mirror base, and contribute to wind noise at road speeds. This OE Match gasket restores proper sealing and finish with a direct-fit replacement that installs easily with the original mirror and hardware.
