I'm a little surprised that you're noticing pitch rotation under acceleration but not under braking. Most people tend to notice roll and nose dive under hard braking more.As it is now the car is pretty flat in corners and under braking, it does raise up under acceleration. Too much IMO.
The easy and arguably best fix would be firmer springs. That's if you really do need this to be fixed . . . how much of this perception of acceleration nose rise/tail squat is based on easy street driving where you don't ever get much?
FWIW, springs that provide wheel rates in the 225 lb/in - 250 lb/in range are not unreasonably stiff for street duty in a car of this weight, provided that the damping is somewhere near right. This would be about where Blue's Option 2 falls.
Videos tend to downplay the amounts of chassis inertial movements, and they certainly don't provide all of the sensations you get from actual sitting-in-the-driver's-seat observation. Chances are, the Steeda car is still rolling about 2°/g including tire deflection effects. I doubt a stock S550 rolls more than about another half a degree per g above that.I'd like it to be as flat as the Steeda Q500 in the above Vid, but that might beat me up in daily driving. ;)
