Brian, F55 didn't come available until 2003. Your '99 has RPO F45 which I'm told can be (after the shocks have been replaced) turned off (tuned) with use of a Tech2. If you know someone with access to a Tech2 (maybe a friend working at a GM dealership) they should be able to do the deed. If not I'd call Chris, Doug, or (Mike69 the best contact person up there) at ECS who can no doubt help you with this.

We just replaced the F45 shocks for one of the guys that works here on his '01. The F45 feature can be turned off with the Tech II tool, or Pfadt sells F45 sims that can be installed.
The various aftermarket tuning programs cannot turn off the F45, it must be the GM Tech II tool.
Wire wound Resistors
271-132
10 watt 10 ohm
(The resistor is a 2 inch X 1/4 inch ceramic block with a solid silver wire on each end. Two in a pack so buy two packs.)
Underneath the car at each shock location there is a black wire running from the shock to a blue connector. The wire does not unhook at the shock but if you trace the wire you will find the connector. Disconnect the blue connector from its mate and remove the shock.
Take a pair of wire cutters and cut the wire as close to the shock as possible. You will be left with the cut wire on one end and the blue connector at the other. Remove about three inches from the black insulation to expose the two wires (black & white) that it conceals. Strip both of them back about an inch.
Insert the resistor into a rubber hose (w/the wires protruding from each end) to protect it; solder the resistor between the two bare wires (black & white) that originally went to the factory shock to complete the circuit. I used some water proof silicone to seal the solder and wrapped everything in electrical tape. Reconnect the blue connector. Tuck the package out of the way and secure with zip ties. This will fool the computer into thinking the F45 Shocks are still there (as the computer looks for its resistance). Install the replacement shock.
Repeat for all four corners and you will be good to go.
300 bucks is meh the car rides fine. I may just not replace it for awhile and save up till someone is selling the z06 shocks? Can anything bad happen? Just drove the car tonight feels fine took it on the highway everything runs perfect

That is pretty much how I did my change to Koni-FSDs several years ago and at the moment PFADTs coil overs are going on
I think they are about $800 a shock and I have 3 good ones left as my left front had an issue with the lower bushing they use and you could not just buy the bushing
I will be installing Z06 shocks in the spring. All four of my f45 shocks are good. You can have one or all of them for free (you pay shipping) if you want.

I love this fourm
Lemme know. I'm not going to rush into buying new ones.
I know its bad because the tuner at rpm plugged his laptop into my car. and said hey. Your front left shock is bad
