        2014 Mustang Saleen

        Nice addition to the car. Saleen used chrome lug nuts on black chrome rims. The blue lug nuts made the car stand out.

        Get what you pay for

        I like that each lug nut is like a lock that you have to use a key to take off. I don't like that the paint flakes off after removing the lug nuts. guess I should have spent more than $40.00 for the set.

        Good deal and adds a different look

        The lug nuts that were on my car were torqued way to much to where some of the nuts ended up snapping right off; and i was just using a wrench. Great buy and brings more life into my Track Pack wheels.

        Blue lug nuts

        They look nice especially on a grabber blue mustang and not only that but they also double as a wheel lock which I dint realize that when I bought them. Only complaint I have is that they scratch very easily

        Look Wonderful but Scratch Very Easy

        I bought these for my 2013 black Mustang, since my theme was black-and-blue. They look awesome on black rims and especially so once I paint the calipers blue. So on the positive side they do look very nice and are well made. On the negative side, they scratch extremely easily. Just from taking off the old lug nuts and putting these on, even with the adapter they give, on about half of the nuts I got a silver ring around the top of them from tourquing. And since I have to take them off to paint the calipers they will probly be even more scratched by the time I get them back on. If you are going to buy these, I would suggest only putting them on once you've done everything else and don't need to take the wheel off again for a while. If you ever need to take your car in to get aligned do not let them use an impact gun on these lug nuts or they will ruin them. You MUST hand tighten. Overall not bad.

        Nice accent

        Very pleased with lugnuts, very light but well made and since I painted my calipers blue it adds a nice touch and really looks good

      Can you purchase a replacement socket and will it fit all the 6 spline sets?

      • A replacement socket, or key, would not be possible for purchase. These 6 spline lug nuts have a change in the design of that key after a certain amount of kits are created.

      I was wondering how these would look on my deep impact blue 2014 GT...I like the look just worried these would be too bright of a blue. Any insight would be appreciated.

      • They look darker on the car. Should match pretty well with the Deep impact. Hope this helps!

      Will this color match grabber blue? I have a 2013 grabber blue V6 mustang and was wondering if it would match my color, thanks!

      • Not an exact match, these are a deeper more metallic blue closer to the Sonic Blue than it would be to Grabber Blue. I think that they would still go well with Grabber Blue, not clash.

      These lugs on sve drift wheels I have the sve drift wheels and currently have chrome 1/2 *20 lugs. Are these the same dimensions? I see the 1/2 but I suppose the 20 refers to the length. Will these be compatible? 2 answers
