Just got a new 540 and need some trunk spoiler install help...

I bought an OEM M performance trunk spoiler - came matte black so I need to paint to match body color - no big deal, ordered some sapphire black spray paint. But the spoiler came with no instructions or adhesive/3M tape - has anyone installed one of these themselves? I have used the 3M tape in the past for spoilers that sit on top of the trunk but this one sits flush to the back - would 3M hold it (and yes, i know the tape is strong but...). I also have a tube of Elch P1 adhesive but I'm worried it will goop out on the car when the spoiler is pressed against it. Thanks!

Thanks. Problem is whether this will work for a spoiler that sits off the back of the trunk lid vs on top.

This adhesive tape which I sent you the link to is made specifically for this spoiler. If you look up the spoiler this tape is listed with the spoiler but sold separately. Not sure why BMW doesn’t just include it with the spoiler but whatever.

ended up just installing the carbon fiber spoiler I ordered before the M performance since I decided to uninstall the M5 diffuser and order a smaller carbon fiber diffuser. the M5 looked a bit silly on a 540. thanks though! I kind of like the smaller spoiler and it sits right at the edge of the trunk.

No worries bro. I was about to send you a picture of the adhesive tape kit. It’s pretty nice. It’s the same exact shape as the bottom of the spoiler to make it a nice flush/even install. Carbon spoiler is nice but a little too small imo. Nevertheless nice and better than not having anything.

i thought it was small too until I actually installed it - fitment is perfect and is actually a little larger than the OEM M550i lip spoiler it seems. it doesn't really sit on top as much as on the back ledge, there's a little indent in the spoiler that fits right to the back of the trunk.
