Not necessarily, this ring is double sided taped on. Screw heads glued with cyano.I like it with and without the rings, but better with. My only warning about the rings would be that if you don't find another set of these pickups to use and you installed the rings, you can end up with holes in your finish that are obvious and would be an issue if you were to sell it. Buuuutttttt.........you can also pickup the rings for pretty cheap now so you could always get a pair from eBay and leave them installed.
Rings look way cool....
