I discovered I have a cracked lug nut. Where is best place to find one?
First time I pulled my wheels today. These things feel like they are plastic, but can't be right? Must be aluminum?

They are alloy-any of the usual parts places will have them. FDM, Sunset, Pelican, etc.
That is indicative of someone cranking down way too hard on them, and not torqueing to spec. Why you never trust an unsupervised tire shop to jack your car or mount your wheels.

i got lugs to delete my wheels locks by posting a WTB in the section on RL, you should be able to snag one cheap. i think there are different kinds though.
you have real wheels,
my turbo twist knock offs feel like they are filled with cement

This is a dry thread value. Make sure your wheel studs are dry with some electrical contact cleaner before using this value. I use a calculated and substantially lower value as I use anti-seize on my wheel studs.

Not sure this is a good idea as the steel nuts are much harder and in contact with the wheel may cause a deformation issue on the mating surface.
This is one of the very few areas where I would use and install the OE solution only.

Tell me how you "calculated" the reduced value of torque. I've often looked for that info.

I am not an engineer and I do not recommend to others to do what I do because the failure mode associated with wheel stud/ fastener failures could be catastrophic. For others I say only use the values provided by Porsche for safety reasons.
I noted your attachment where it suggests using some sort of special lube does not require a reduced value. This is inconsistent with what I have come to understand from fastener engineers. A lubed fastener pulled to a dry fastener torque value may be pulled beyond its elastic range and in the case of very hard steel fasteners such as wheel studs the range is quite narrow and I would feel an over torqued fastener could stretch or fail precipitously. It is pure speculation on my part but the reasoning about the lubricant not changing the value may be based on reasoning or testing where the soft metal (aluminum) nut acts as a self-lubricating fastener as the metal is substantially softer than the stud. If this is the reasoning I would feel that the Porsche published torque value for the aluminum nuts would be lower than the steel nuts.
