  • Page 3: A Message From Iracing

    – the Ford GT40. Designed and constructed at the direction of Henry Ford II following Ford’s failed bid to purchase Ferrari in the early 1960s, the Ford GT40 debuted at the 24 Hours of Le Mans in 1964. After a couple of heartbreaking defeats at Le Mans, the Ford GT40 scored a dramatic victory there in 1966, the first of four consecutive wins for Ford at the French classic.

    FORD GT GT3 | INTRODUCTION LOADING AN iRACING SETUP Upon loading into a session, the car will automatically load the iRacing Baseline setup [baseline.sto]. If you would prefer one of iRacing’s pre-built setups that suit various conditions, you may load it by clicking Garage > iRacing Setups > and then selecting the setup to suit your needs.

Making adjustments to the following parameters is not required and can lead to significant changes in the way a vehicle handles.

The difference between cold and hot pressures can be used to identify how the car is progressing through a run in terms of balance, with heavier-loaded tires seeing a larger difference between cold and hot pressures.

    FORD GT GT3 | ADVANCED SETUP OPTIONS | CHASSIS Chassis FRONT A RB BL ADES The configuration of the Anti-Roll Bar arms, or “blades”, can be changed to alter the overall stiffness of the ARB assembly. Increasing the number of ARB arms will increase the roll stiffness of the front suspension, resulting in less body roll but increasing mechanical understeer.

    FORD GT GT3 | ADVANCED SETUP OPTIONS | CHASSIS FRON T M AS T ER CY LIN DER The Front Brake Master Cylinder size can be changed to alter the line pressure to the front brake calipers. A larger master cylinder will reduce the line pressure to the front brakes, this will shift the brake bias rearwards and increase the pedal effort required to lock the front wheels.

Increasing the spring perch offset will result in lowering this corner of the car while reducing the spring perch offset will raise this corner of the car.

    FORD GT GT3 | ADVANCED SETUP OPTIONS | CHASSIS HS RBD DAMPING : High-speed rebound adjusts the shock in extension over bumps and curb strikes. Higher values will reduce how quickly the shock will expand, while lower values will allow the shock to extend more easily. Despite not having as much of an effect on handling in result to driver inputs, High-speed rebound can produce similar results in terms of aerodynamic control and uncontrolled oscillations if set improperly.

    FORD GT GT3 | ADVANCED SETUP OPTIONS | CHASSIS C A MBER As at the front of the car it is desirable to run significant amounts of negative camber in order to increase the lateral grip capability however, it is typical to run slightly reduced rear camber relative to the front. This is primarily for two reasons, firstly, the rear tires are 25 mm (~1”) wider compared to the fronts and secondly the rear tires must also perform the duty of driving the...
