So the other day I was washing and detailing my car and noticed something that I found kind of wired.

3 of my stock 07 SS/SC 18" wheels have a lip, right side the main outer part of the rim(pic will show you, no idea how to describe it)





Then my 4th wheel doesn't... (driver rear)





I'm assumeing that the first owner wrecked one of the wheels and replaced it with a prior years'.

Are the ones with the inner lip the 07 wheels and the ones without the 05-06?

And yes I searched for this, didn't find anything

 

thats really odd

 

Heres a better pic I found on Ebay.

Thoes lips make it a real pain in the ass to clean too. lol.

 

You have the '07 gunmetals which are Malibu wheels and look like poop IMO, your other wheel is indeed an 05-06 gunmetal.
