Ford ROUSH Mustang Supplemental Owner's Manual page 15

Coil Over Suspension
If your ROUSH Mustang is equipped with the optional coil over suspension (height adjustable or three
®
way adjustable) regular cleaning of the spring perch is recommended to prevent the build-up of debris/dirt
accumulation, which can lead to noise concerns. Spraying off of the spring perch during regular washing and
applying white lithium grease between the spring and the spring perch/mount will help alleviate coil bind
between the spring and the perch.
Suspension Adjustments
If suspension adjustments are made, the residue from the tamper proof labels should only be removed using
soap and water. Dry using a soft cloth.
Some ROUSH vehicles may be equipped with adjustable suspension components. Changing ROUSH factory
® ®
settings may change the vehicles ride, handling and dynamic responses. All Roush vehicles meet the
requirements of FMVSS 126 & 135 as delivered utilizing the factory settings.
The vehicle owner will be responsible for, and liable for, the resulting vehicle dynamic behavior if the
suspension is adjusted away from the factory settings. It is recommended that a vehicle dynamics expert is
consulted before adjusting suspension components.
If damper settings are changed or there is doubt that the factory settings are in place; then the following
instructions will enable the factory settings to be reinstated.
