Seized lug nuts.

Anti-seize. I had a cat fuel filter gall to the base due to lack of anti-seize....

Oops. Titanium

I’ve used anti-seize on lug threads for 40 years without a single issue. And without a single seized lug nut. I’m convinced.

The older porsche lug nuts are Aluminum T6 at least the classical black "alloy" lug nuts holding on so many fuchs and similar

Subaru is known for cheap grade lug studs.
You may also want to research replacing the lug nuts with aftermarket like McGard

Like I said, oops…I was always told they were titanium. Misinformation I guess.

My problem is swollen nuts. But you probably don't want to know

I've always used a very small amount of plain old grease on lug nuts.

I also apply a thin smear on the matting surfaces of the wheel and hub and I've never had an issue.

Same. The other tip is to always make sure that the threads are 100% clean, (this goes for all fasteners in my OCD world). I have a collection of those copper bristle tooth brushes that I use constantly and use WD40 liberally as a solvent to wash away dirt and grit.

There was a hilarious thread ~20 years ago on the 911 tech board about whether people re-torque their lug nuts at the track...tried to find it...comedy gold from some OGs.

Maybe someone with better search skilz can pull it up.

What I was thinking right from the start. Also do a quick inspection of the threads to see if any are damaged.

I've done the same thing. No issues with nuts coming off and no seizing or galling and low wear. The question of using or not AS on lug nuts/bolts has many threads and opinions on the web.
I like to avoid issues - e.g. cold rainy night and getting a flat and have a hard time getting a wheel off.

This is what I do.
