TYRES
The Ferrari 12Cilindri Spider can be fitted with Michelin Pilot Sport S5 or Goodyear Eagle F1 Supersport tyres, both of which were developed in a new size for the Maranello company: 275/35ZR21 at the front and 315/35ZR21 at the rear. Development benefited from physical and virtual sessions, the latter carried out through simulator testing to reduce the number of physical prototypes and, consequently, development times and cycles.
Performance has been optimised thanks to the adoption of the latest technologies in terms of compounds, tread design concepts and casing characteristics. Extensive testing has led to improved performance, dry grip levels and balance, stability on the limit and in the wet, as well as improved comfort and noise characteristics both internally and externally, including a 10% reduction in rolling resistance compared to the previous Ferrari front-engined V12 berlinetta applications.
CHASIS
The Ferrari 12Cilindri Spider’s all-aluminium chassis, featuring a 20-mm reduction in wheelbase compared to the 812 GTS, is completely new: specific attention was focused on the geometry of cast components such as the shock towers and A and C pillars, to improve torsional rigidity whilst simultaneously reducing weight.
The result was an increase of 15% in torsional rigidity compared to the past, which ensures more predictable dynamic behaviour, with consequent benefits for suspension precision. Thanks to more extensive use of castings, the number of extruded components requiring assembly has been significantly reduced, making the assembly process more efficient. Lightness was a key requisite throughout the entire development of the chassis and body-in-white of the Ferrari 12Cilindri Spider, which weighs just 60 kg more than the Ferrari 12Cilindri – a remarkably small weight increase made possible by the innovative solutions developed specifically for this car.
