FR During the early postwar years Borrani made a new disc wheel series called “CABO” (from our founders initials) targeting custom and one-off vehicles. They were offered with, or without, the centre-lock system, a light alloy rim and had 5 slim windows for brake cooling. In 1955 the CABO wheels were updated with 10 “Turbo” style windows in a classic oval shape.
The Turbo wheels were offered as: Normal with steel rim, Sport with light alloy rim and Sprint with light alloy rim and centre-lock system. The R1-257 was designed during this transitional period. The original drawings from the archive are dated 17th of September 1954 with the design noted as the CABO series RD3099. The wheel was re-named the following year to coincide with the release of the new Alfa Romeo Giulietta. In 1956 the “Turbo Sport” wheel was priced at 12,000 Lire compared to the 7,000 Lire for a standard steel wheel
The Borrani Turbo Sport R1-257 wheel
The Borrani Turbo Sport R1-257 wheel, designed to fit the Alfa Romeo Giulietta and all models of Alfa Romeo Giulia (generally called “Bimetal”), is finally available once more. This true Borrani re-release has been manufactured using our original drawings. This offers to every Giulietta enthusiast a sporty and elegant alternative to the standard steel disc wheel. The bolt-on R1-257 4.50”x15” “Turbo Sport” uses the original Alfa Romeo hub cap while the “Turbo Sprint” series uses the Rudge centre-lock system, being held on by a 2 or 3 eared spinner.
Borrani can offer a full transform kit to allow the fitment of centre lock wheels to cars currently using bolt-on wheels. The Turbo wheel is supplied as standard with a light alloy rim and a silver painted centre but is also available, upon request, with a 5” or 5.50” wide rim and custom colours.
The Borrani Bimetal wheel, as well as being used on custom and sporting Alfa Romeo Giuliettas, can give an elegant touch to all cars thanks to our high polished light alloy rim!
