They have about 9k miles. I'm switched to a Sachs racing coilover setup. One of the front springs is not pictured bc I gave it to a tech I work with bc his snapped. I told him he can order me a new one so it is currently being shipped to the shop for me to swap back out.
They're a small step better than the oem
MO30 suspension Porsche offers. There isn't any cons besides they aren't height adjustable.
