Maybe they have changed them up a bit since I bought a set? The ones I got were quite rounded looking, didn't have the same stepped edge as originals and had a completely different set of clips than any GM type rings. When you attach them to the wheel, the 4 sets of pointed clips (like little spikes) really gouge into the rim and scratch the wheels quite deep. I tried one and ended up repainting the wheel after the ring hacked it up pretty good. Summit sells them as well as Heartbeat from what I was told, and they also sell their caps which were 100% plastic. Back they went. Maybe alright for a driver type car or their repop rally wheels, but not for anything a level up IMO. Hope this helps.
