    To that end, we have provided baseline setups for each track commonly raced by these cars. To access the baseline setups, simply open the Garage, click iRacing Setups, and select the appropriate setup for your track of choice. If you are driving a track for which a dedicated baseline setup is not included, you may select a setup for a similar track to use as your baseline.

    LOADING AN iRACING SETUP When you first load into a session, the iRacing Baseline setup will be automatically loaded onto the car. If you would like to try any of the other iRacing pre-built options, you may select it by going to Garage > iRacing Setups > and then selecting another option that fits your needs.

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.

    PORSCHE 911 GT3 R | 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. Higher values transfer more force through the arms to the ARB itself, increasing roll stiffness in the front suspension and producing the same effects, albeit on a smaller scale, as increasing the diameter of the sway bar.
  • Page 18 PORSCHE 911 GT3 R | ADVANCED SETUP OPTIONS | CHASSIS T OE -IN Toe is the angle of the wheel, when viewed from above, relative to the centerline of the chassis. Toe-in is when the front of the wheel is closer to the centerline than the rear of the wheel, and Toe-out is the opposite. On the front end, adding toe-out will increase slip in the inside tire while adding toe-in will reduce the slip.

    PORSCHE 911 GT3 R | ADVANCED SETUP OPTIONS | CHASSIS C A MBER Camber is the vertical angle of the wheel relative to the center of the chassis. Negative camber is when the top of the wheel is closer to the chassis centerline than the bottom of the wheel, positive camber is when the top of the tire is farther out than the bottom.

  • Page 24: Rear End

    PORSCHE 911 GT3 R | 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...
  • Page 25 PORSCHE 911 GT3 R | ADVANCED SETUP OPTIONS | CHASSIS A RB O U T ER DI AME T ER The ARB (Anti-Roll Bar) size influences the stiffness of the rear suspension in roll, such as when navigating a corner. Increasing the ARB size will increase the roll stiffness of the rear suspension, resulting in less body roll but increasing mechanical oversteer.
