My 911 Goes all Aero

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.
