Magnetic Front License Plate Mount
As I posted in another thread, I ended up visiting Rennline last week so they could do a final test fit of their screens for the 991.2 GTS. In anticipation of that, I reached out to a company called K&J Magnetics (kjmagnetics.com) to get a recommendation for what size and strength of magnets I should use. We decided on 4 of each of these:
Part numbers are BX084BR-N52 AND DC6BR-N52 and they are rubber coated.
I then took the stock license plate bracket:
I roughed up the areas where I planned to place the magnets (very close to where the screws would go) with a little sandpaper:
And then used some 3M 5200 Black Marine Epoxy to secure the magnets to the plate (if I were to do this again, I would use JB Weld Epoxy instead of the 3M Epoxy because the 3M stuff takes SEVEN DAYS to cure. Lucky thing I was planning ahead:
Two other things I would do differently after going through the full install process: don't put too much epoxy on top of the magnet, I ended up having to sand it down to get the plate to sit flush. Additionally, the lower 2 magnets should be moved up 1/2"-1" higher because the plastic center fill insert partially blocked where I had put them.
While the bumper was off for the fitting of the grilles, I used the JB Weld (which sets in 5 minutes and fully cures in an hour and is readily available on Amazon or in the store) to attach the inside magnets.
You can see in this picture where we had to "field modify" the plastic insert to notch it where I needed the magnets to go based on where I put them on plate bracket:
I let the JB Weld cure and grabbed a bite of lunch, then the bumper was put back on and voila:
After sanding down the epoxy on the back of the mounting plate, this sits exactly flush as if it were screwed on and the strength of these magnets is really impressive. It takes a pretty good tug to get the plate off. The person on 6Speed that did this said he had driven over 100mph with this plate on the front and there's no sign that it ever moved at all. The bracket has a guide to automatically center the plate on the car, so it's easy to find the center. I've only driven locally with mine so far, but I'm pretty comfortable that this will only come off when I want to pull it off. I'll update this thread from time to time confirming that I still have a front plate!
(I don't plan to leave it on most of the time. But when I travel in the area around NYC there's a higher risk of getting stopped. In 5.5 years of ownership of my Panamera I was stopped 3 times for not having the front plate on. Twice I was just given a warning, once I was given a ticket. I plan to just put it on when I'm in the higher risk areas, and if I'm stopped without it, I will just say that when I washed the car I forgot to put it back on, and would it make a difference if I just put it on now? Then take it out of the frunk and pop it on. We'll see how it goes!)
I hope others can benefit from this!

I think for the front bumper magnets, 3M VHB double sided tape would work great to hold the magnets, as the force being applied to the bumper magnet by the plate bracket magnet would tend to keep the bumper magnet in place in the first place (and the 3M tape would prevent the magnet from moving), and would avoid having to use epoxy on the bumper. The plate bracket magnets definitely need to be epoxied. Also, if the black plastic insert below the plate bracket can be removed without removing the bumper, you might be able to do this with the bumper in place. In any event, excellent idea!
