I didn't need the aluminum ring. I did need to take apart the horn button to get at the horn spring, then using pliers I bent the bottom of the spring, which now follows the red dotted line, to keep it out of the way during assembly. The horn wires are a bit of a joke, as one wire is suppose to attach to the center lug that your thumb is on... but once attached, it prevents re-assembly, as there is no room for it. Then the electricity is suppose to travel thru 2 bolt heads... it might last a few steering wheel attachments, but I doubt it would last long or be reliable. I do like the custom DF logo thou, even if it isn't a horn on my car. The logo is glued to black plastic, so I wasn't able to back light it. The wheel felt good quality, as did the suede leather/pleather, and all the aluminum parts. I did have to use the chrome allen head machine bolts on the black aluminum horn ring... I was hoping to use the black button allen head bolts, but they weren't long enough.
