I bought these to cover the chrome nuts on my 2006 MX-5 on my aftermarket wheels. I pulled out my calipers, measured the lugs and figured they would fit. So I ordered the black set. They arrived quickly and fitted the wheels well until I realized I had fitted wheel locks to one of the studs. Of course they wouldn't fit. I contacted the company and within a day they spoke to me, figured out my problem and sent me a set of large ones to fit wheel locks for an additional $5 and an option to return them if they don't fit (I'll report this after I've warmed them up have, they fit perfectly in the wheel locks!). Keep in mind that they are recommended for OE installations, not aftermarket as stated in their promotional material which I have ignored. However, they tried their best to help me. I appreciate that very much! These are USA made products that come from Minnesota (as far as I can tell from the return address). I am happy to do business with them, especially after experiencing their amazing customer support!
