None, except possibly a slightly lower ride height. Check for FHP on 550s by looking at the part numbers on the Hydraulic Steering ECU, the Shock Absorber ECU, and the spring numbers on the paper tags. You can also measure the diameter of the rear anti-roll bar. Should measure about 23.5 mm for FHP and 17.5 mm standard, including paint thickness.
If she still has the FHP pads, the brakes will likely squeal, too.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
