Well I cannot honestly answer your question as far as which way to go. We have not got the Mopar spribgs in, and I have yet to see a vehicle with them on it. I cannot say the drop will be less than the 1.6" factually, we are under the impression it will be less based off of some feedback from Mopar. They did not specifically say they will be less, but we heard they were not happy with the current setup and they were reworking them a bit. Again the amount of drop you go will really play a role in the areas your drive in, some driveways already cause the undercarraige to scrape without a dropped suspension. You should pay attention to entrances, exits, and speed bumps that may be on your everyday paths of transportaion. This could help you decide just how much lower your car could stand and continue to be a daily driver. (With that statement the air bagged systems really gain appeal)
