Giannini was a Rome-based car tuner that specialised in the Fiat 500. Just like Abarth had the 595/695 SS, Giannini had the 590 GT. 

The GIANNINI 590 GT is born in 1964. The engine of the Fiat 500 is reamed in 586 cc and can give 31 hp. GIANNINI wanted to rival the most important opponent Abarth. The factory based in Torino built the 595 since 1963 and reached 27 hp. However, the scorpion’s factory deviated the 595 in elaborated versions SS and also a 595 SS Assetto Corsa.

The 590 GT features a modified cylinder head, compression ratio 8.5:1 all ports are enlarged and ground, stroke increased to 77.5 mm, crankshaft modified and balanced with lightened timing and 30°-70°/70°-30° diagram. Solex C28 1B2 carburettor. Optional features include ventilated wheel rims, monogram fan, sport tachometer, short gear ratios, 8/39 axle ratio, and even front disc brakes. Aluminium tappet cover with Giannini lettering.

As an option, there are aluminium wheels, monograms and set of initials, sports dashboards, shorts conic couples and also front disc brakes.
