How cold does it get in Florida?
In Melbourne (Australia) our climate is very mild. Max temps in winter rarely drop below 10°C and top out in summer just above 40°C (can get into the high 40's, but its not very common). Mins overnight in winter rarely get to 0° (can on the local mountains on occasion, but generally stay positive), in summer they hang in the high teens or low 20's.
With that in mind, I generally don't notice that much of a change in suspension between summer and winter. However my last 4 cars have been lowered with very stiff suspension (S8 is softest by far since my first car!), and the roads around here aren't too flash either...
That being said, basic physics says warm springs will be softer and warm oil will be thinner, which you should be able to feel if sufficiently in tune with your car.
