20mm "Thread on" wheel spacers. These are exact reproductions of the original wheel spacers used on the rear brakes of Spyders and 356 Carrera's. These race cars ran 60mm front brakes (20mm wider than production 356 front brakes) and therefore the wider rear track greatly improved handling. The spacers were originally made to threat onto the 14mm wheel studs so they could not fall off during pit stop wheel changes.
Our "Thread on" wheel spacers will only fit 14mm lug studs. We also sell long and extra long 14mm press through studs.
