The only time that would be required is if you are encountering pinion angle issues from a drastic drop. With a 1.5'' drop, your pinion angle should be fine. Having said that, every car is a bit different and I have encountered vibrations before on a car in the past with this type of drop. If you are experiencing rear vibration at highway speeds and the tires are balanced properly, I'd check the pinion angle to determine if you need these.
