I never seen these earlier 18" coupe wheels with Enkei on the front lip:

Infiniti G37 18" 2008 2009 Enkei Rear Hypersilver Factory Wheel Rim 73703 | eBay


Are these authentic?

 

Look to be OEM G35/G37 wheels from 07-09 to me. Never seen them in that color though, only chrome. But take that with a grain of salt.

 

Those appear to be an OEM G37 08, 09 (not 07) standard Coupe (non Sport) wheel. Enkei is the manufacturer of G37 OEM wheels
I assume it has been refinished. Keep in mind that, although not impossible, it is difficult to match the paint exactly on Infiniti wheels

 

I know Enkei is the manufacture of oem G37 wheels and I know these are the earlier coupe wheels. The problem I have is that I have never seen Enkei name on the front lip of these wheels, usually on the back of these wheels. I have only seen the Enkei name on the front lip on later G37 wheels (not these). That is why I am curious if these are authentic.

 

It seems to be authentic. From doing a little more searching they added Enkei on the lip on the 2010+

Here is a thread with pics of them:

Good find. Now you know

 

Good find except they are remanufactured. There is no telling what the damaged condition to the wheels was before they were reworked and refinished. There's probably a 50 /50 chance that one or more out of a full set won't spin true. Having said that, I do believe they are authentic non-sport coupe g37 wheels. Two years ago I bought a set of 2 authentic Enkei factory new g37 wheels for $450 delivered. The particular eBay dealer had 8 wheels available at the time. The price on these remanned wheels is not exactly a bargain. I generally prefer used wheels with minimal blemishes versus remanned wheels where the damaged condition prior to repair and refinish is an unknown.

BTW, i've seen these wheels with the Enkei nomenclature on the outside or the inside surface, with no rhyme or reason as to model year. It seems to be more related to factory run vs model year.

 

No disagreement here. I stand by the fact that the link the poster found was good without exception.
