These low profile wheel nut lugs are used in some types of DPR bolt on wheel spacers. They are 1.5P thread pitch and priced per each nut. They stand 14.2mm tall so will not recess into the body of a 15mm spacer (you need at least a 20mm spacer for these). They take a 19mm socket. Note these will NOT fit the G-racing wheel spacers as they require a 17mm socket. Sold individually.
