Looking for a new aggressive stance to compliment your Mustang, while still obtaining a quality ride Look no further. ROUSH Performance offers this lowering spring kit for all 2005 - 2014 Mustang owners, both GT and V6 applications. These springs will be a direct swap - out for your factory springs, and install in about 3 hours. Included will also be a detailed installation guide so you can get your Mustang back on the road in no time Not only do these springs help to provide a better ride quality, they also provide a nice aggressive stance over stock When added to a 2005 - 2014 Mustang GT (or V6 model), these springs provide a .50 inch drop over the stock ride height (Note Ride height variance dependent upon vehicle content installed). On 2005 - 2010 Mustangs, when used with the ROUSH Front Struts and ROUSH Rear Shocks, vehicle ride height will drop to roughly 1.00 inch over factory ride height.
