Mustang GT Street Performance Build
The S550 Mustang GT responds well to two straightforward upgrades
that change how the car feels without touching the engine internals.
The SCT BDX unlocks more power and sharper throttle response through
a plug-and-play ECU calibration. The Eibach Pro-Kit brings the ride
height down about an inch front and rear — tightening the stance and
improving cornering response on factory dampers.
