    Hello. Will these lug nuts fit on my 2014 mustang with rotiform KPS? Greetings Patrick


    • Unfortunately we do not carry that style of Rotiform, however it looks like they may require tuner style lug-nuts. I would contact the seller directly to verify the correct type of lug nut for the Rotiform KPS.

    Are these the "tuner" style lug nuts required for the RTR Tech 7 Wheels?


    • The Tuner Style Lug Nuts are required in order to install the RTR Tech 7 Wheels because the stock (13/16") lug nuts are too large.

        These lugs are very sturdy and we haven't had any break in the past. I'm sorry to hear one of yours did during installation. I'm going to have a replacement set shipped right out for you!

      New Stylish 6-Spline Lug Nuts

      I recently purchased and installed these lug nuts, and love them. Their design makes every one of them a security lug nut. Without the adapter, no one could ever steal your wheels. By replacing my chrome lugs with the black ones, they blend in better with my wheels, too. Good looking, easy to install, and more secure. What more could anyone ask for. Love it.............

      Spline Key cheap aluminum

      The lug nuts look cool with the black wheels that I bought however when I used the adapter key for the lugs for the second time, it broke and scratched the inside of my wheel when it gave way whey I was loosening my lug nut. Everything but the adapter is good.

      Black Lug Nuts

      They are solid and have great black color. The black is glossy. They all come individually wrapped and then put in a box to hold them all. That's a nice touch but some how some of mine were chipped and it reveled the chrome behind the black which doesn't look good if you have all black wheels. I would have sent back if I wasn't so excited about putting my wheels on. That's why I gave it 4stars. I would purchase again but anticipate having to send back due to chipped paint.

      Great price

      I bought some new wheels from another company and the lug nuts they offered were much higher in price and less appealing. These are great and well worth purchasing. NOTE: the stock photo makes the nuts look like they are anodized black, but these are painted and look great. The tool I received is crome, not black like in the stock photo.

      Impresive Nuts!

      These black lug nuts are great! They match my nice black rims, and no problems at all so far. (Knocking on wood) It would be nice if the adapter has a small magnet on the bottom, or maybe a thin rubber coating to help keep it in the socket. Mine fell out and but a little scratch in the chrome lip of my new Foose rims. Still giving it a five, since if I would have noticed the potential of it slipping, I would have been more careful.

      Works but a minor issue with fit.

      The lug nuts work for the intended purpose but the socket has sharp edges that scratch off the black coating every time you use it. Had the manufacturer buffed and rounded the edges of the socket it would be a good product. It's all in the details........

      black lug nuts

      came in a box with my mirror covers. they came out of the big bag and were just rolling around in the box hitting the mirror caps. Not a good thing. luckily the mirror caps were covered pretty good and had foam on them. they are much smaller than the factory ones, make it look nice and clean. i like that they are basically all locking nuts. good stuff
