I have the Steeda shocks/Struts/springs and adj panhard on my 07 V6, they really change the game, much better handling, really dials it in. I had a bunch of other stuff installed at the same time, but it's all really labor cost. Also I really recommend to upgrade the strut mounts to the GT500 ver. and the camber adj bolts, maybe the steeda bump steer too.

I debated the adjustable KONIs, but for the price difference, I went with the unadjustable.
