Roush Performance Mustang Lowering Spring Set Front & Rear - 1" Drop

This and every ROUSH® suspension part is extensively engineered and tested by ROUSH's own performance engineers to give optimum performance for your vehicle. ROUSH suspension parts are generated over many hours on the race track, slalom, lane change, skid pad, and on a wide variety of different road surfaces to provide the best combination of ride and handling.

ROUSH engineers use the DIVAS Data Acquisition System, which is the same system used by Ford engineers, for collecting and analyzing vehicle dynamics. Rather than simply providing the best quality suspension parts available, ROUSH takes its development a step further by finely tuning its suspension offerings to the specific application as part of a whole system. The advantage of this approach is that ROUSH suspension parts work seamlessly with the other dynamic aspects of your car.
