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. -
Page 6: Loading An Iracing Setup
Upon loading into a session, the IR-01 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. -

Page 11: Chassis
DALLARA iR01 | ADVANCED SETUP OPTIONS | CHASSIS Chassis The Dallara IR-01 features a simplified suspension design which forgoes dedicated springs for each corner of the car, as you would see in a road car or most other race cars. Instead, heave (pitch) and roll are handled independently via front and rear Heave Springs and Anti-Roll Bars, respectively. - Page 12 DALLARA iR01 | ADVANCED SETUP OPTIONS | CHASSIS 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.

DALLARA iR01 | ADVANCED SETUP OPTIONS | CHASSIS REAR A RB S T I FF NES S The ARB (Anti-Roll Bar) stiffness setting adjusts the roll stiffness of the rear suspension via a change in the ARB’s diameter. Increasing the ARB stiffness will increase the roll stiffness of the rear suspension, resulting in less body roll but increasing mechanical oversteer. - Page 15 DALLARA iR01 | ADVANCED SETUP OPTIONS | CHASSIS S PRI NG DEFLEC T IO N This displays how much the Heave Spring is compressed from its total length under static loads in the garage.

The value represents the amount of steering rack movement for a single revolution of the steering pinion, with larger values resulting in a faster steering feel.
