After much back and forth I've decided to go with air suspension on my 11 4s. I'm having the car shipped to my country. I was originally going to go with H&R springs but due to bad roads, and speed bumps the size of small cars, I'd feel better being able to lift the car over small obstructions. I've read of complete PASM removal on other Porsche cars with the Durametric coding feature, but they don't seem to offer coding on the Panamera. Am I stuck looking for a PIWIS?
