Re: Lug Nuts for Stock and Aftermarket Wheels on the S550
@Moto has sourced the correct lug nut and I purchased one form my local NAPA Auto Parts to confirm that it fits the N4SM R Spec wheels. He found them on ebay at a reasonable price. I'm sure Ford Performance will have some available soon but these have a much larger seat/cone than the tuner luts I purchased from Summit. Dorman 611-257 is the part number. The one on the right is the correct one.
I don't want to go the longer studs route will just order the right size wheel lug nuts from Dorman or get back to OEM ones for now. Problem is my OEM ones are gone gone so will need new one oredered Dorman 611-257 based on this tread but looks like they are only for extended length studs .I think most people put the long ARP high strength studs in. Not a huge job and adds a pretty good margin of safety, you will for sure have full thread engagement plus some. Yeah, they stick out, but aesthetics are secondary to safety in a track day car.

At the moment I'm replacing my wheel hubs often enough to not worry about the studs though maybe a good idea to go with longer ARP ones will think about it. At the moment more concerned with not having lug nuts that work ... In Europe usually take like a few weeks for parts to arriveIf you don't want a longer stud, at least look for a stronger stud. Track use is hard on studs.
