On "normal" NGs the flight spoilers only move to 33 or 38° deflection, only the ground spoilers move to 52/60 degrees. On the SFP all spoilers, both flight and ground, will deflect to 60 degrees on landing. Many airlines, especially those serving small warm water airports have opted for parts of the SFP enhancement for their fleet to enable higher performance out of short fields, some didn't take the two position tail skid for example.
