Roush lowering springs for 2005–2014 Ford Mustang (GT and V6) provide a direct swap to achieve a more aggressive stance while retaining daily usability. The springs install in roughly three hours and include a detailed installation guide. On Mustang models they typically yield about a 0.50-inch drop from stock; when paired with Roush front struts and rear shocks on 2005–2010 cars, ride height can approach a full inch lower than factory.
