My original thought was just to change the tires, but while driving home from the dealer (1200 miles) and locally with my wife and kids we felt like the back was very bouncy and you definitely felt the sway when trucks passed or going on turns.
Didn't want my wife or kids to feel car sick and was trying to get ahead of it by upgrading the suspension. Last thing I want is everyone feeling sick after our first trip out and not wanting to go on another trip.
I also figured since they were replacing the tires, changing the suspension components would not add that much in labor cost.
