– 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 Introduction The information found in this guide is intended to provide a deeper understanding of the chassis setup adjustments available in the garage, so that you may use the garage to tune the chassis setup to your preference.
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.

FORD GT GT3 | ADVANCED SETUP OPTIONS | TIRES & AERO ADVANCED SETUP OPTIONS This section is aimed toward more advanced users who want to dive deeper into the different aspects of the vehicle’s setup. Making adjustments to the following parameters is not required and can lead to significant changes in the way a vehicle handles.
FORD GT GT3 | ADVANCED SETUP OPTIONS | TIRES & AERO HO T AI R PRES SURE Air pressure in the tire after the car has returned to the pits. 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 | TIRES & AERO RE AR RH AT S PEED The Ride Height (RH) at Speed is used to give the Aero Calculator heights to reference for aerodynamic calculations. When using the aero calculator, determine the car’s Rear Ride height via telemetry at any point on track and input that value into the “Front RH at Speed”...
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.
FORD GT GT3 | ADVANCED SETUP OPTIONS | CHASSIS T R AC T ION C ON T RO L S E T T ING The position of the traction control switch determines how aggressively the ecu cuts engine torque in reaction to rear wheel spin.

FORD GT GT3 | ADVANCED SETUP OPTIONS | CHASSIS S PRI NG PERCH O F F S E T Used to adjust the ride height at this corner of the car by changing the installed position of the spring. 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 S PRI NG S ELEC T ED/S PRING R AT E Similar to at the front axle, stiffer springs will result in a smaller variance in ride height between high and low load cases and will produce superior aerodynamic performance through improved platform control at the expense of mechanical grip.
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...
