BODYWORK

A stress-bearing steel monocoque with both the external panels and box-section superstructure are galvanised-coated on both sides, two-door coupé, four seater, longitudinal front engine, rear wheel drive. Cx 0.33.

CHASSIS

Chassis made from high resistance galvanised steel with a rear tubular sub-chassis to support the suspension and gearbox, and a front tubular sub-chassis to support the suspension and engine.

SUSPENSION

Front: double wishbones with arms and hubs in forged aluminium; progressive rate steel dampers or optional continuously variable aluminium gas dampers with adaptive damping and acceleration sensors on each wheel (Skyhook system), co-axial coils and springs.

Rear: double wishbones with arms and hubs in forged aluminium, additional radius arm to control toe-in; progressive rate steel dampers or optional continuously variable aluminium gas dampers with adaptive damping and acceleration sensors on each wheel (Skyhook system), co-axial coils and springs.

19” Trofeo-design alloy wheels; front 8J x 19, rear 9.5J x 19 Tyres, front 235/35 ZR19, rear 265/30 ZR19

BRAKES

Brembo braking system with four cross-drilled ventilating discs. Front 330 mm x 32 mm, rear 310 mm x 28 mm; alloy four-pot callipers with differentiated diameter: front 46- 38 mm with ceramic insulating seals; rear 34-30 mm. Brake pads: Ferodo HP1000
