They are for real vehicles my friend.Standard metal material chrome plated.
I had them on my Flame cut wheels on my truck, until I broke a wheel (not spinner) on the way to a fire call. I replaced the wheels and have had these in the garage.
I have never had spinners but would like them and I like the flame design. Can these attach to any rim that has a removable middle cap? I am not familiar with how they are attached to the rims. Thanks
