Someone recently told me these were the wrong lugs but I've never known infiniti to use any other. But I'm a bit paranoid now so I wanted to confirm.

These are the aftermarket black lugnuts from z1/concept z and are sold as oem lugs for stock sport wheels

 

Yes they are.

 

Looks like it, here's mine.

 

OEM wheels require mag-style lug nuts. The "IPL" wheels are still OEM and still require mag-style. Do NOT use the conical style.

 

The picture was for reference only, the lug nut on the right. The one on the left was used in comparison for something else when I took the pict. It’s a Rays M12 1.5 anyways. My bad, should have mentioned that.

 

No worries, @typeii . Just wanted to clarify for future readers.

 

I wonder what the engineering reasoning is for the two. Total surface contact looks about the same. Probably a manufacturing or marketing decision

 

I'm sure there's a ton of scientific reasoning between the different types of lugs/ nuts that involve way too many physics laws and equations that would fry my brain.

Maybe someone more in the know could chime in... for Idle curiosity's sake.
