Well, I think you're just looking for something unique, to set your car apart from others. The OEM wheels are actually of very high quality, and take into account weight and strength. The 18" wheels are light cast wheels by BBS and the 19" wheels are light forged wheels by Fuchs (both German companies, and Germany has some pretty tough regulations regarding wheel specs - such as the TUV). If our cars came with anything else, and the Tire Rack sold our current wheels as non-OEM, then we'd probably think they were the shiznit and buy them up
