Hey their jonnbr,
Welcome to the Forum, and I would be more than happy to answer any of your questions on dropping your PT. . Cost wise you are looking at $250.00 to $350.00 range for springs, and $2500.00 + range for air ride plus installation. Here is the pick from above that shows the difference between my custom 3" / 5" drop springs I custom made, and my air ride to give you an idea between the two.
I can also explain how to get your PT to drop all the way to the ground like the last photo above, but it is expensive, and a lot of work to pull it off.
At the moment, I just need a bit more information from you on what you are looking at doing.
1. Which way are you thinking about going, drop springs, or air ride?
2. How low do you want to go?
3. Do you plan to add a Body Kit at some point down the road?
I can help walk you through how to do anywhere from a mild drop, all the way down to fully slammed like my PT is sitting in my last photo above. Just need to know where you want it to be.
Go easy, let me know, and I will catch you later.
