Today I installed the Pedders Coilovers and Sway Bars kit for my 2016 Mustang GT. This kit provides a nice drop and an improvement in performance. As I understand BC makes the actual shocks for Pedders. Both are brands with experience in racing and street performance. I found this to be a moderate to challenging job depending on your experience with mods and working on cars. If you have a well equipped shop this is definitely doable yourself. On jack stands in a small garage or driveway it may be a bit hard to do.
