I'll take the panhard bar if you decide to split them up. Out of curiosity did you have any odd consequences of running the non adjustable arms and lowering springs? Looking at the picture of your car if looks like you have lowering springs.
These are off of a friend's car who was at stock ride height. That being said, I think having the panhard bar adjustable is the most important part.
11-14. Most of the stuff will fit 05-14, but I think the upper arm and/or mount is different for 11-14
