If you buy the spinner caps from Summit, I had to get longer attaching screws. Easy enough, found the proper stainless screws at Aubuchon Hardware. I used medium Locktite as well. The spinners are cool but make getting to one of the lug nuts a real pain, need to use and impact universal swivel. I broke my Snap-On 3/8" universal trying to get a lug nut off last year.
