The body will not be made entirely of carbon fiber, with the front and rear frames being aluminium. This increases the weight to around 900 kilograms.
The chassis of the car weighs only 65 kilograms and is a single carbon fibre body, just like that in supercars. Outer body is made of composite material which is 20% lighter than steel body, stability is comparable to steel and better than aluminium.
The 4C has a high quadrilateral suspension at the front and MacPherson struts in the rear. Resultant weight distribution is 38% on the front and 62% on the rear axle. The front and rear rims are a different diameter and width; 205/45 R17 front and 235/40 R18 back as standard, with optional 205/40 R18 and 235/35 R19. Both wheel options are shod with Pirelli P Zero tyres. The 4C has ventilated disc brakes in all corners, in front Brembo 305 millimeters and in the rear 292 millimeters. The car can stop from 100 km/h in 36 meters. To save weight and increase steering feel, the 4C has no power steering.
