Replacing BMW emblem

[Bumpy]

Wow ! ..
So many opinions here...

Size of Rondels ....
Why not just take a minute and measure it ?
It was my understanding that the front is 70 and the rear is 82.
I just measured the front and it is 70 mm.

If you are considering 'sticking' on any trim, I would recommend 3M Two sided automotive trim tape. You can get it in two strengths (permanent and semi- permanent)
You can cut it to fit irregular shapes. I used it to reattach my Z4 emblem on the rear, and its been through two Canadian winters with no problems.

Removing emblems ...
I would avoid a metal knife. Just asking for scratches or stitches !
If you go that route use a plastic pry or even a spatula.
I prefer using monofilament fish line as my experience with dental floss hasn't been good.

Cheers and Best 'o' Luck

Thanks Bumpy... problem isn't measuring the size of the existing badge - that's easy... but non colour standard replacement badges don't seem to be available at 70mm - either 68mm or 73mm is all I can find in the black emblem design

edit: removed my post, as yours was obviously a typo

you're right.. the front IS 70mm.. however, the 73mm will fit in the recess, but does sit proud when compared to the original.
however, you can also trim the 73mm to fit quite easily

What you mean 'trim' which bit and how?

On either side of the back of the badge, at the edge level with the the lugs, you can 'shave' a centimetre up and a centimetre down from the lug with a craft knife or dremmel in a kind of concave cut. The lowest point needs to be 2 or 3mm deeper than the rest of the edge. I'd put a photo up from another post but I can't find one right now, and the one I had modifies by another member got nicked over a year ago

I do know it will need stuck on with silicone adhesive behind the badge and in the lug holes though (or strong double sided tape) because, as pointed out above, the lugs are not long enough to attach the self tapping nuts behind the bumper.

Thanks Bing any further information / images would be much appreciated

So today I replaced my boot emblem. I thought I’d share some additional advice, which I I didn’t see above. I’m not sure how the last roundel was put on my boot lid, but gently prying the roundel off of the lid, eventually required snapping the roundel lugs, which were FIRMLY lodged in the black plastic grommets. There wasn’t enough to grab onto with needle nose pliers (I tried) so I eventually used a Dremel tool with a small drill bit to remove the stuck broken pegs. I didn’t damage the grommet, but having extras on hand isn’t a bad idea. Mine must have been glued in.

thank you for your help

I did indeed what you said and took one kidney and replaced from inside, 70 mm here a picture so everyone knows how it looks like from inside
