If you haven't done this yet, replace your rear shocks with Koni FSD units. My wag only has 26k miles on it, and with 19 inch wheels (which I'm selling in another thread, link at bottom) the ride over bumps was starting to get on my nerves a bit, mainly because of the different in how the front end felt vs. the back end when traveling down the road.
I installed the 24.5mm rear sway bar by Elevate a few weeks before and it improved the handling a great deal, but at freeway speed, (LA area) a quick lane change or offramp turn made the rear end feel like it wanted to come around. In essence, made the front end feel a bit "darty". Now with the FSD's out back, the harshness of the rough city bumps is smoothed out dramatically, and the car handles very composed like, with the big sway bar out back.
In short, it's amazing and transformative for the ride quality and the handling. Don't wait, order from Tire Rack and they will be on your door step in about a week.
