The problem isnt overtightening its lack of lubrication. That is just lazy...

Don't put antisieze on the seat. it can split the rim and cause it to crack to the center. If you use any antisieze, only use it on the threads, and only use a very tiny amount one time.

Get steel lug nuts if you want a solution that is fail safe. Hand tighten only, and use a torque wrench.

Bull.
Its in the porsche manual to lub both thread and seat.

Correct - do what the engineers at Porsche tell you to do - threads AND the convex seat of the lug nut

"A little dab 'll do ya"

Bulletin also says always use a perfect (literally) P300 tool everytime, nothing else.

Everyone here has one ?

thanks for posting this one, great info this technical letter.

John Walker said it! use a sharp pointed round chisel, about 5-6 inches long. Hit it straight initially, then in the same hole that you made (indentation) hit it carefully to rotate that part to the left (to loose it) be careful to avoid damaging each wheel; Use a good penetrating oil before chiseling it! An old mechanic saying..."Nothing was born there, someone put it there"

Best of luck,

There's only 3 local P-shops in our/your area. I find it hard to believe the one in Elmsford or Bedford Hills did that to your car and had the balls to charge you for taking them off.

My second car, a rusty '69 2002, had steel lug nuts that refused to come off. My dad suggested I take it to the local service station and see if they'd put some heat there. Voila, came off like butter. I don't know how this will work with alloys, aluminum, and steel.

Hang on - they charged you to undo their mess? How long ago did they put the wheels on?

Yep. Working at an air cooled Porsche shop, I learned Heat is your friend for unsticking many things. The techs don’t have days to wait on penetrating oil. MAP gas takes a couple minutes.

I removed one with a hole saw, the metal is soft and it was easy to cut.

Do you mean a round punch? What's a round chisel?

A center punch, like you use for making an indentation before drilling.

A center punch is not a chisel. That was my point.
