Tip: Don’t stack adjustments. Make one adjustment at a time and test it.

Bold face remedies are the go-to fixes for each symptom. You might try those remedies first.
This matrix is based on the components in the iRacing Advanced Legends Ford ’34 Coupe. These settings apply to any asphalt oval cars although there are fewer settings on the Legends car.
If you are going to make any spring or cross weight adjustments, please see this page first.
If you see any errors or have any questions, I can usually be found in Discord.
