The F45 is the actual suspension parts - springs, sway bars, shocks, etc.
Active Handling is a system that monitors the car's attitude in a curve and corrects for the driver's intended line via individual application of brakes to the separate wheels.

Active Handling - originally designated as JL4, is a system that will actually apply opposite front brake to control a spin. Option F45 is a suspension package that is adjustable for sport or touring, by adjusting the shock valving. F45 was replaced in '03 by F55 which is commonly referred to as Magnetic ride.
Active handling became standard equipment in '01 - and was optional starting on later model '98's.
Here's some more info on Active Handling....

What is the suspension considered if it is not upgraded to the F45/55

The Active Handling system is a safety system that helps correct understeering or oversteering by using sensors to detect that control is being lost. These sensors include a steering angle sensor, yaw-rate sensor, lateral accelerometer and sensors in the ABS and Traction Control systems and will selectively apply brakes and spark retardation as needed in order to help correct the situation.
Active handling, optional since 1998, standard on all Corvettes since 2001:

The second generation Active Handling system makes use of the F45 suspension (if your car is so equipped) for stability control. It would make sense that the F55 suspension is also used by the current Active Handling system for stability control, but I have not confirmed this.

Z51 is the best suspension option. It allows tighter cornering.

To the best of my knowledge, Active Handling does not utilize the F45 or F55 for input to the A/H system computer. The non F45 and F55 cars A/H work just like those with it. If the F45 and /or F55 were required for A/H to accomplish it's task, then one of those two types of suspensions would be required on all A/H equipped Corvettes.
Again that's to the best of MY knowledge.
BTW, the Z51 suspension is the better of the two suspensions, FE1 VS Z51.
The 2001 - 2004 FE4 Z06 suspension is the best, with the 04 Z06 shocks being the best within that grouping for handling. The F55 provides the best controlled ride of all, and because of the increased control over road irregularities, better handling can be achieved over non-F55 cars with the base suspension. That's to the best of my knowledge, with some opinion thrown in for good measure.
