Roll Steer Dialog¶

The Roll Steer properties for the selected wheel location are displayed and edited using this dialog box. This dialog is used for independent suspensions; for solid and tandem axles the single-coefficient Roll Steer Properties dialog is displayed instead.

The dialog title identifies the current axle and side.

Roll Steer Graph¶

Graph titled Roll Steer vs. Jounce/Rebound showing the wheel steer angle produced by the polynomial coefficients below, plotted against suspension jounce/rebound deflection.

Roll Steer Constant Coef (deg)¶

Initial steer angle at zero suspension deflection (constant term of the polynomial).

Roll Steer Linear Coef (deg/in)¶

Linear coefficient of roll steer vs. jounce/rebound deflection.

Roll Steer Quadratic Coef (deg/in²)¶

Quadratic coefficient of roll steer vs. jounce/rebound deflection.

Roll Steer Cubic Coef (deg/in³)¶

Cubic coefficient of roll steer vs. jounce/rebound deflection.
