1. Left and right throw needs to be the same. For the most part the left EPA and right EPA won't be equal to achieve that. A quick and dirty way to do this is to drive the car in a circle at full steering lock and make sure that the diameter of that circle is equal left and right.

2. Chassis balance. If the car isn't balanced left to right, there will be a different amount of weight transfer left and right, thus resulting in a different steering reaction and feel.

3. Shocks, ride height, tweak. This is somewhat related to the weight balance above to. If your car is tweaked, or if your ride height isn't equal left to right (and thus / or) your spring preloads are different enough left to right, or if your shocks aren't equally smooth/rebounding/damped left to right, the car will react differently.
