No they are different.
The image I posted up are the genuine OEM Nismo LMGT4 black steel lugs that come with the original LMGT4 wheels.
These are what you want, if you want to stay authentic.
Remember that the normal size hex will not fit in the LMGT4 wheel aperture, as it is smaller.
The size you require is M12XP1.25 17mm hex.
If you go more than 17mm hex you will damage the wheel.
Plenty in stock if you are not sorted.
