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.
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.
MCLAREN 570S GT4 // DASH PAGES PIT LIMITER When the pit limiter is active a large blue box containing ‘PIT LIMITER ON’ will appear at the base of the forward dashboard along with the illumination of the two centermost shift light LED’s.
MCLAREN 570S GT4 // ADVANCED SETUP OPTIONS 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.
MCLAREN 570S GT4 // TIRES Tires C OLD AIR PRES SU RE Air pressure in the tire when the car is loaded into the world. Higher pressures will reduce rolling drag and heat buildup, but will decrease grip. Lower pressures will increase rolling drag and heat buildup, but will increase grip. Higher speeds and loads require higher pressures, while lower speeds and loads will see better performance from lower pressures.
MCLAREN 570S GT4 // CHASSIS Chassis FRONT ARB SE T T I NG Increasing the ARB setting shortens the ARB moment arm and will increase the roll stiffness of the front suspension, resulting in less body roll but increasing mechanical understeer. This can in some cases, lead to a more responsive steering feel for the driver.
MCLAREN 570S GT4 // CHASSIS IN-CAR DIALS BR AK E PRES SU RE B I A S Brake Bias is the percentage of braking force that is being sent to the front brakes. Values above 50% result in greater pressure in the front brake line relative to the rear brake line which will shift the brake balance forwards increasing the tendency to lock up the front tyres but potentially increasing overall stability in braking zones.
MCLAREN 570S GT4 // CHASSIS LEFT/RIGHT FRONT C ORNER W EI GH T The weight underneath each tire under static conditions in the garage. Correct weight arrangement around the car is crucial for optimizing a car for a given track and conditions. Individual wheel weight adjustments and crossweight adjustments are made via the spring perch offset adjustments at each corner.

MCLAREN 570S GT4 // CHASSIS SPRING PERCH OFF 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. These changes should be kept symmetrical across the axle (left to right) to ensure the same corner ride heights and no change in cross weight.
MCLAREN 570S GT4 // CHASSIS LEFT/RIGHT REAR RE AR RIDE HEI GH T Distance from ground to a reference point on the rear of the chassis. Increasing rear ride height will decrease rear downforce as well as increase overall downforce and will allow for more weight transfer across the rear axle when cornering. Conversely, reducing ride height will increase rear downforce percentage but reduce overall downforce while reducing the weight transfer across the rear axle.

MCLAREN 570S GT4 // CHASSIS REBOUND S T IFFNES S The rebound stiffness setting is a paired adjustment controlling both the low and high speed damping characteristics of the damper with identical ranges to those of the front dampers. Increasing rebound damping will slow down the rate at which the damper extends in both low and high speed situations.
MCLAREN 570S GT4 // CHASSIS REAR FUE L LE V EL The amount of fuel in the fuel tank. Tank capacity is 110 L (29.1 g). Adjustable in 1 L (0.26 g) increments. ARB SE T T I NG Increasing the ARB assembly stiffness will increase the roll stiffness of the rear suspension, resulting in less body roll but increasing mechanical oversteer.
