does anyone know if gm has two different kinds of 18 inch rims (not chrome) made for the cobalt ss supercharged. my car was hit on the driver side and i had to replace a rim. the rim i got is the same rim but its had some differences to it. the color is a little different and the other rims on the car are machined not solid metal like the new rim is. did gm make a "machined" rim or do i have rims that are not produced anymore.

 

06 and late 07's were slightly different cut. Mine (06) are flat on the front, 07's had a slight dip in the middle.
