FERRARI F 550GTS
F550 GTS
The F 550 GTS is a racing version of the Ferrari 550 Maranello. It has been developed especially for entry in the FIA GT World championship, the Le Mans 24 hrs. and other endurance races. It follows the classic sports car principle with a front engine driving the rear wheels. An optimal weight distribution is achieved due to the gear box being mounted in the rear.
Body
The chassis is fitted with a roll cage fabricated from high tensile steel tube, various suspension pickup points are integrated in to the cage's construction.
An extremely stable side impact protection has been fabricated on the driver side of the vehicle.
Body construction
With the exception of the roof, all the body panels have been replaced by very light and extremely resilient Carbon / Kevlar components. In order to achieve a high down force on the rear axle, a large wing with a range of adjustments has been mounted on the rear of the vehicle. The vehicle has an enclosed floorpan with front and rear diffusers. The rear and side windows have been replaced with polycarbonate.
Cockpit
To further save weight both the original dashboard and centre console have been replaced with carbon fibre.
The driver is seated in a carbon-kevlar seat with a six point harness which is repositioned towards the centre of the vehicle. A race sport steering wheel has been fitted. Competition battery cut-out switches have been installed in place of the standard items. The electrical fire extinguisher system and dry cell battery are positioned on the passenger side of the vehicle.
Suspension
The pick up points of the wishbones have been raised in order to lower the car. All bearings have been replaced by spherical bearings. The compression and rebound of the height adjustable suspension, as well as the front and rear anti-roll bars are fully adjustable.
