103 F430 Challenge Ferrari has also reaffi rmed the strong link between its GT and racing divisions with the F430 Challenge which is specifi cally designed to meet the expectations of its sportier clients. The F430 Challenge has the same general look and 490 CV engine as the road-going version. However, it also incorporates a large number of signifi cant track-oriented modifi cations and a host of new features not seen in its predecessor in the series, the 360 Challenge. The transfer from Formula 1 is signifi cant, particularly with regard to the braking system which uses carbon ceramic material (CCM). The electronic gearbox is also F1-derived and works in exactly the same way as the one used aboard the grand prix car. Fifth and sixth gear ratios have also been modifi ed with respect to the road-going version as has the fi nal drive ratio in order to make the very most of the engine on all the circuits the F430 Challenge will race. 19'' slick tyres were also developed specifi cally by Pirelli and are designed to comply with the very strict racing regulations that demand endurance whilst still delivering blistering performance. The F430 Challenge boasts a kerb weight of just 2701 lbs (excluding fuel.) Weight has been reduced in every area of the car, from the engineering to the bodywork. Of particular note are the Lexan® windscreen, the all-carbon fi bre intake plenum cover, and the specifi c exhaust system. The most notable of the other solutions introduced is the new steering wheel with a quick release mechanism to make it easier to get into and out of the car. The wheel is also equipped with buttons for radio contact with the pits, to set the pit lane speed and interface with the new colour digital instrument panel. The rear of the car is characterised by a new exhaust system which has high central tail pipes, and by the modifi ed grille which increases the extraction of hot air from the rear of the engine bay. The anti-roll bars, springs and single-rate shocks have all been modifi ed for racing use too. The centre locking wheels make wheel changes faster too as does the fact that the car incorporates pneumatic jacks.
