The 911 from 1974 to 1989 was equiped with the “Flag” door mirror. Made of good old fashed foundry metal they are heavy units and weigh in at 1,700g each – that’s a wopping 3,400g per pair. Don’t get me wrong, the Flag mirrors are great but in an attempt to freshen up the look of my old classic 911, I decided to fit a pair of Aero mirrors which were developed for the 964 and 993 variants of the 911.
The Aero mirrors cost a small fortune from OPC so I scouted round for a second hand pair. I found mine at Type911 in Bromely, Kent. Matthew is a great guy and did a good deal on a pair of unmarked second mirrors including the glass.
Flag mirrors are made fro a cast iron base unit, but the main mirror is produced from plastic. As a result the Aero mirror weighs on 900g each or 1,800 per pair. Thats a huge saving of 1,600g. Doesnt sound much, but as the saying goes, “every little helps”. Besides, I think the Aero mirror is a much sleeker cleaner look for the classic 911.
Fitting the Aero mirrors is simple. The Base plate mounts ndirectly into the pre-exisiting
holes drilled for the the Flag mirrors, so its a simple matter of a direct swap. The mirrors I bought were the wrong colour, so I decided to strip the mirrors down and spray them properly and re-assemble afterwards. This isn’t as simple as it sounds. The base plate and mirror housing are held together by a really powerful spring which keeps the two parts together by way of a cam. In order to seperate them you have to make a spring compressor which will compress the spring sufficiently to relive pressure from the cam in order to pull the two parts together. You can make this from a bolt, steel eyeletts and some washers. The most difficult part was re-assembley.
Anyway, despite the difficuilty in taking the mirrors apart, I’vm very pleased with the final result.
