I was hoping to use these on my stock rims but they do not come with a washer for the conical nut so an open center hub cap can be used. I didn't like the look without the center hub cap. I will continue to work on a washer that works with the conical nut to make my cap fit! I definitely like the look of the product and they fit my rig and hold the set torque. I have not left them long enough to check the finish and other properties. For now I would only recommend aftermarket wheels.
