Ford Performance partnered with Eibach to develop these purpose built lowering springs for the 2013 Cobra Jet factory race car program. Luckily these coil springs fit all 2005-2014 Mustangs and they are the best choice for serious racers. Wound with optimum spring rates, they provide repeatable launches with amazing traction and high speed stability. These springs also provide an aggressive stance with an approximate 2 inch drop in the front and 1 inch drop in the rear.
For further improvement, we recommend Steeda's Anti-Roll bar which will keep your S197 flat and the rear tires perfectly planted for lowest ET's possible.
