The LCA's are different, I forgot, my bad.

All the cars I have had, I changed out the LCA to the box'd style.

Just go pull some off of a car at the junkyard, and box weld them, makes them stronger and not flex. Makes a HUGE difference. Tightens up the rear a lot.

You have gotten a ton of good advice on here, what have you decided?

Full coilovers, or sleeves, and struts?
