At first I bought a few different ones that looked very cheap and small, but they are pretty close to the '04 Vette OEM tabs. It is difficult to tell when they are in the hub (see photo). I'm not sure how safe they are, and I doubt anyone will still be using the original wheels: the $1,700 run-flat tires on wheels are more of a problem. For the price they are very good. Make sure you save the information provided as there is a place to rearrange the unlock socket if you lose it. I ordered a second one as a backup just in case. There were 5 of these in the pack so stock up.
