The Challenge Stradale has been derived from the 360 Modena and maintains the same basic approach and architecture.
However significant changes have been made to the suspension system and set-up. The titanium front and rear springs are stiffer more rigid than on the 360 Modena (around +20%), and whereas the rear anti-roll bar has a larger diameter. These interventions have increased resistance to roll and to dip and in general terms have made reaction to direction changes more rapid, giving the driver a more direct feel of the car.
Damper settings have been reviewed and defined specifically for this model. The car's centre of gravity has been lowered by 15 mm.
The tyres are Pirelli P Zero Corsa type - this new Pirelli super-low profile tyre adopted specifically for the Challenge Stradale measures 225/35 at the front and 285/35 at the rear and is fitted on 19" Challenge-style wheels secured by titanium bolts. The choice of these tyres exclusively for the Challenge Stradale confirms the effectiveness of cooperation between two of motoring's historic brands, not only in the case of the Ferrari Challenge-Pirelli Trophy but also in the FIA GT Championship. A long series of tests carried out together with Pirelli has identified a tyre compound and tread design that maximises torque transfer red to the road surface and produces very high lateral acceleration (1.3 g) while maintaining superb balance between the two axles. The innovative characteristics of this tyre, which makes de its world debut at the Geneva Show together with the Challenge Stradale, means grip can be adjusted to suit the thermal conditions under which the tyre must perform.
Carbon Ceramic Brakes
The braking system on the Challenge Stradale comprises carbon-ceramic (CCM, Carbon Composite Material) discs: the result of highly advanced studies conducted by Ferrari in conjunction with Brembo, the supplier of this system.
Dimensions of the brake discs are as follows:
front: 380 mm diameter x 34 mm thickness; and a differentiated-diameter, 6-piston calliper;
rear: 350 mm diameter x 34 mm thickness; and a differentiated-diameter, 4-piston calliper
The carbon-ceramic system installed on the Challenge Stradale, together with the aluminium brake carriers, makes for astounding performance and short braking distances. levels.
In terms of weight, the reduction achieved for the Challenge Stradale is 16% when compared with conventional brake discs.
Overall deceleration rates for the Challenge Stradale are 15% better than for the 360 Modena.Published 6 March 2003
