| Tight in Middle | 
        Increase rear stagger Increase top wing position (move forward)Decrease tube heights front and rearIncrease left front rebound stiffnessDecrease left rear wheel spacing | 
| Tight on Exit | 
Increase rear stagger Increase top wing position (move forward)Decrease top wing angleIncrease right front torsion bar diameter*Increase  right rear torsion bar diameter*Increase right rear bump stiffnessIncrease left front and right front rebound stiffnessDecrease left rear wheel spacing | 
| Tight Throughout Turn | 
Increase right rear tire pressureIncrease rear stagger Increase top wing position (move forward)Decrease left front torsion bar diameter*Increase right front and right rear bump stiffnessesDecrease left rear wheel spacingIncrease right rear wheel spacing | 
 
  * When making changes to torsion bars or any changes to the chassis that also changes the tube heights, use the torsion bar stops to return the tube heights to their original values.
Bold face remedies are the go-to fixes for each symptom. On the iRacing Sprint Cars, you should be able to stick to those and make any adjustments you need without going any further.
