Mustang Coil Springs (Rear Set), from ROUSH®, will improve the handling of your 2005-2014 Mustang.
These rear springs provide more stiffness and stability for your Mustang's suspension, and improves cornering ability. The Mustang Coil Springs are designed to work as part of the ROUSH Mustang Suspension Kit (part #401296) to provide superior handling without sacrificing ride quality. The ROUSH Rear Coil Springs are sold in pairs (for both left and right rear shocks).
This and every ROUSH suspension part is extensively made and tested by ROUSH's own performance engineers to offer optimum performance for your vehicle. ROUSH suspension parts are developed over many hours on the race track, slalom, lane change, skid pad, and on several different road surfaces to produce the best combination of ride and handling.
One instrument that the ROUSH engineers use in this development is the DIVAS Data Acquisition System, the same system used by Ford engineers for gathering 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 benefit of this approach is that ROUSH suspension parts work seamlessly with the other dynamic aspects of your car.
