The Eibach Pro-Kit for the 2011-2014 S197 Mustang uses progressive rates tuned per model: roughly 1.0" front / 1.5" rear on GT, 0.8" front / 1.2" rear on the V6, and 0.6" front / 1.0" rear on the Boss 302. It lowers the center of gravity for less body roll and nose-dive while keeping a streetable ride on the factory dampers.
