It will then require a change in the tie rod length to be in proper alignment so the radius of the arc will change as well. If the radius arc of the tie rod is longer than stock on a front steer setup then the car will have more toe understeer. If the same scenario was applied to a rear steering design, then the car would exhibit less toe understeer.
It will subsequently necessitate a modification in the tie rod length to be in optimal alignment, causing the radius of the arc to change as well. If the radius arc of the tie rod exceeds the standard dimensions on a front steer setup, the car will experience more toe understeer. Conversely, applying the same scenario to a rear steering design would result in less toe understeer.
