These are an open ended version of a factory style lug nut. I call these “Longballa Specials”, because my friend Scott Longballa requested I make them for his beautiful builds. Early racers would drill out the ends of their factory lugs nuts and it would allow them to run longer wheel studs to assist with quick wheel changes. These are available in a black PVD finish. This is a full set of 20 and M14x1.5 for Porsche studs with the correct R14 ball seat.
