Having just purchased a 2012 Ford Mustang GT, I felt that many aspects of the vehicle's performance were phenomenal, however the suspension left me wanting more. While the car provides good lateral grip in corners and performs better than any other generation of stock Mustang, the soft spring rates contribute to excessive body roll and front-end pitch under heavy braking.
To cure this, I pulled out the big guns and installed KW's Variant 3 Coil-Over. While the Variant 1 allows only for height adjustment with KW factory pre-set damping, and the Variant 2 provides height adjustment and adjustable damper settings, the Variant 3 gives drivers independent control of both rebound and compression, along with a wide range of height adjustment.
Installation only took two hours with a lift and a few of my friends. KW even includes vehicle specific install instructions and recommended shock settings. While the car now rides on a much higher spring rate than factory, the dampening takes out some of the harshness associated with lowered cars. It really rides quite nice and shows a huge improvement in handling. The car lays flat into corners with minimal roll and is much more stable under acceleration and braking.
