1989 FX3 New Shocks Install
Finally got around to installing new Bilstein FX3 shocks. Got a good deal on the price at Wild Vettes. Installation was the easiest I have ever experienced on a car. Course, had 28 years of grime and too much chassis lube to cut through first. I think the cleaning took me longer. What is it with guys and grease guns?
The Selective Ride computer was throwing every single error code it knew beforehand so I was squealing like a girl when all the codes cleared at start up. I am quite happy that all of the original actuators work fine -- at least for now.
On the ride, the softest setting is quite comfortable and a bit floatey. Can't tell much difference in the middle, but the Perf setting is noticeable. So, to me, they could have eliminated the middle setting. More road miles through the Texas Hill Country will tell.
I was hoping that some of the staccato jolts that shake the whole car would mellow out now but not so. Is this just the nature of the overall suspension system? Or perhaps the leaf? Can this jolting be mellowed out with software springs?
It's nice to start the car and not have a light glaring at me from the message center for a change.

So, the article mentions that the FX3 system with Z51 came with the softer rate stock springs. I think this makes sense since the system can tighten up the shocks. And the car does ride nicely in the softest setting.
My confusion is in the occasional jolts that shake the whole car. It's like their is no dampening at all. The tires are new, not old and hard. Is this some kind of bushing issue?

What setting are you in when you feel this "jolt"? I feel nothing like this in my 1990 unless I'm in Performance mode and hit a big hole in our bombed-out streets here in Tucson. I normally run Sport mode.
Sorry about Harvey, that was a mess!

Did you use new rubber bushings in the top?

Dampening means to make wet.

Course, with all the rain we've had everything is a bit moist.
Good question on the setting. I'll attempt to make some kind of log, but I am guessing it's just the C4 chassis.

Congrats on getting the FX3 up and runnin again. I got mine going about three years ago or so. I was lucky that the previous owner had not chopped off and tossed the actuators. He had plastic bagged them and tucked them into the frame. I agree that there is a noticeable difference between Tour and Perf. Also agree that they could have skipped the Sport setting. My 1991 is an RPO Z07 car which i believe has stiffer springs. I too feel every bump in the road. Swapping in a different rear leaf would probably make a softer ride, but i am not willing to search out what would work and what would not work. Maybe someone else can chime in on that aspect. Either way, going through a clover leaf with that suspension is a lot of fun. Car hangs right in there.

The guy simply let the original shocks age and go dead. Someone told me that after a couple of fault codes, the FX3 computer just barfs up everything. In fact, all the codes cleared after changing just one shock, which I new was totally bad since it was almost limp.
I've driven the car a few more times since my first post and I think I'm done with the suspension except for the inevitable job on the bushings. They are all cracked but still in place. It's unfortunate the original rubber is not available anymore -- just harder poly-based pieces. Some of the guys here like the car better with the poly, but I am skeptical. I suppose I don't have a choice.

I thought some vendors carried rubber but not totally sure.

No, the codes cleared on the first shock. I replaced all four.
