S550 SIGNS OFF.

The sixth generation reaches its final year. Compare actual factory equipment and service records when choosing between late S550 variants.

With independent rear suspension across the regular range and an international launch, S550 made the Mustang a more global sports car. EcoBoost, GT, Shelby, Bullitt, and Mach 1 each offered a different interpretation.

IDENTIFY THE CONFIGURATION.

A model year is the starting point. Confirm the body style, engine, transmission, axle, market, and factory packages before comparing specifications or ordering parts. A restored or modified Mustang may no longer match its original build.

This year has an overview and source directory. Individual trim and powertrain records are not yet transcribed; use the original year-specific publication for those details.

OWNERSHIP NOTES.

Check service records, cooling and fluid condition, gearbox operation, and evidence of track use or tuning. Verify the exact engine, transmission, axle, and brake package before following a workshop procedure.

The imported 2016 workshop manual is not a substitute for this model year’s service information. Use the correct factory publication.
