Hey Mango,
I had my friend mount the spacers on for me. I watched him and he said started to put the original black lugs to mount the spacers on. I told him that those were to be mounted on the rim and not the spacer. He laughed as he already tried and the only way they fit is using the original black lug nuts to mount the spacer, then the supplied grey ones to mount the rim to the spacer. It was a perfect fit. Only problem, was that the lugs showing were no longer black. It was not a big deal to me. Im very happy with the new look. I have no complaints.
