Borrani

It was run by Carlo Borrani at Via Ugo Bassi 9, and quickly became supplier for Alfa Romeo, Bianchi, Lancia and other racing cars, used by such drivers as Enzo Ferrari when winning the first Coppa Acerbo in Pescara (1924).

Borrani wheels used aluminum alloy rims instead of steel, improving unsprung mass and thus overall performance compared to the original Rudge-Whitworth design.

[3][4] The company name was changed to Ruote Borrani S.p.A. in the 1930s, due to Benito Mussolini's campaign to remove English loanwords from the Italian language.

[citation needed] Borrani wheels also were original equipment on famous makes like Lamborghini, Alfa Romeo, Maserati, Facel Vega and Aston Martin.

In 1955, the company relocated to Baranzate in north-west Milan and merged with Costruzioni Meccaniche Rho S.p.A.[3][4] At this time, 1/10 of the annual volume of about 1,500 wheels were for Ferrari racing cars.
