I've moved my driver side mirror forward and while the angle is much better and more in my line of sight, the mirror vibrates and shakes so much on the track, that it's not that useful as an actual mirror.   

 

I suspect I need to add some reenforcement under the door skin - it's currently just using a couple of fender washers that don't really provide much stability - the door skin itself  doesn't seem to be very stiff in that area. I've considered drilling two holes in a length of, say, 6" x 1.5" steel plate and using that in place of the fender washers, but am worried that those might end up deforming/denting the door skin (and while it would give front/back stability, I'm not sure it would really help with up/down vibration (which is I think most of my problem).

 

So... any advice for best way to stabilize a relocated mirror?   

 

Thanks!

We didn’t notice that being a big issue when just bolting straight to the skin. So I wonder, is it possible that coincidentally the mirror adjusting mechanism is now loose and it’s not really the entire mirror shaking?

That's good to know!   My mirror appears to be firmly mounted inside the fairing, but the whole assembly easily shakes up and down.  I've compared to my passenger side (still in its original location) which is quite solid and doesn't really move at all.    

Next time I get the car off the trailer so I can get the door open, I'll remount the driver's side more firmly.   Good to know I probably don't need any magic bracing.

Who's got the wind tunnel data comparing standard and alternate mirror locations?  NA only please.

I do, but I won’t share. Rules say we can move them, limited to 10 inches as I recall.

Or it could be that we oscillated in sync with the mirror. :)

Visualizing... We kept them up high where the skin is curved and unlikely to flex, so that may be the difference.
