Excellent handling and ride quality!
Replaced my stock springs with the Eibach Pro-Kit. At the same time changed my shocks/struts with Koni STR.T's. Combined my mustang handles better and rides more comfortably. This is the best of both worlds without compromise!! It may not have lowered the full 1.5" but my goal was ride and handling, not lowering - so I think it looks great and more important functions!!
