From the early 1920s until the mid 1960s the Rudge-Whitworth design wire wheels were the standard for almost all race cars. Ferrari chose them for the street and race cars and used them as standard equipment or an option through the Daytona series in the early 1970s. The Rudge-Whitworth design wheels were made in Milan as Carlo Borrani wheels until 1961 and as Ruote Borrani after that. They were made with splined hubs and were attached with a central locking nut with two ears and later three ears. These wheel nuts or knock-offs were designed to be removed using a lead hammer. Several different designs were used throughout the years. Inside Plug 250 (from and early P.F. Spyder)
The Rudge – Whitworth type hubs use regular machine – type bearings and require a hub puller to remove the brake drums or discs. Two size were common to most Ferraris. The R.W. 42 design was used on most of the cars, while a smaller R.W. 32 design was used on the 275s and the 330 G.T.C.s.R.W. 32 Hub Puller for the 275s and 330 G.T.C.s
The inside plug twelve cylinder cars had a set of tongs that was used to pull off the spark plug boots when changing the plugs. The plugs were located “inside” the V of the engine between the intake manifolds and were very hard to reach by hand, particularly on a hot racing engine. The early tongs were black. After about 1957 the later tongs were cad-plated. Black Spark Plugs Boot Tongs
The tool kits also contained a short flexible hose to be attached to the grease guns for rountine lubrication of the chassis. The early ones had a bronze woven exterior. The later ones had the brass hose plated with Cadmium. Cad – Plated Grease Gun Hose for the later cars (After about chassis #1,500)
