Stiffening doors by replacing plastic film with Perspex/Plexiglas

[L777JDP]

Hello,

My feeling is that the vibration experienced by the door-mounted mirrors is due to the buffeting on the plastic, which moves, and that movement is transmitted to the mirror. One solution might them be to unpick the stitching, remove the plastic and replace it with some thin, but much stiffer Perspex/Plexiglas to fit inside the exposed metal frame.

This could not be stitched in place, but could be glued in place, perhaps with the black sealant used for guttering on both sides to re-attach the black fabric surround.

I've seen a thread from 2015 where someone cut away half the door to fit Perspex to the outside of it, and have no black surround at the top and the back, which is what got me thinking.

Has anyone tried anything along these lines? Interested in the experience regarding mirror vibration.

Just fit mirrors to the windscreen stanchions ... and get used to the fact you can't throw the doors open on to the bonnet.

You can throw the doors if you have the recent bulk buy mirror mounts. 

Exactly my thoughts - don't mess with the doors, just fit Spa or similar mirrors on the stantions.

Possibly consider the lack of any aerodynamics in the door mirror design as being the source of “buffeting”? Strengthening the door or mounts is likely to only modify the character of buffet induced distortion.

Never suffered - or never noticed in the last 18 yrs of commuting.

Reposition the door fastening straps a little to put more tension on them. It's never going to be crystal clear, but you don't need it to be.

Just fit mirrors to the windscreen stanchions...

Agreed.  That was one of the best mods I've made.

This is what is referred to above, excellent bit of kit, no vibration and sidescreens still open fully.  You could try asking in Marketplace or make some yourself with aluminium or perspex.
