## History

GISA was born in Biancavilla, common on the slopes of Etna, in 1991 due to the will and passion of Salvatore Giardina, after an intense activity matured in the world of competitions both as a driver of grand touring cars and as a preparer.[1][2]

## Automobiles

The GISA cars are two-seater and single-seater, with rigid tubular semi-load-bearing steel frame covered with super light aluminum alloy panels or molded carbon fiber panels. The front and rear suspensions are formed by overlapping triangles (Push Road) with shock absorbers and springs produced by the company itself; on request, as well as with an engine of own production, they can be coupled with engines of other car manufacturers (Alfa Romeo, BMW, Renault)[3][4][5] and a sequential Hewland FTR / JFR gearbox and steering wheel controls. Tires can vary in conventional configuration (Ant. 8.2 / 20.0-13 Post. 12.5 / 23.0-13), (Ant. 7.5 / 20.0-13 Post. 10.5 / 23.0-13) and radial (Ant. 195 / 530-13 Post. 290 / 570-13), (Ant. 195 / 530-13 Post. 250 / 570-13). The double braking system usually consists of 4-piston calipers and self-ventilated front and rear discs. The rubber tank (FIA) is available with a capacity of 12 L for uphill competitions and 45 L for track competitions.[6]

* 3D modeling of the part in a CAD modeler;
* Assembly and Verification of the part in the Assembly model;
* Export of the 3D model to a compatible machine format;
* Part realization as "prototype" in PLA, ABS, Wood, PU or other material;
* Check part functionality;
* Final part realization with part CNC machine tool;
* Cleaning and finishing;
* Anodizing, polishing or painting of the part;
* Assembly of the final product.
