I bought a new set and the standard valving is different from what came as OEM in my 90. I noticed the difference right away in the Sport & Performance settings. It seems that they are just a bit softer than the OE stuff in the initial stages. The FX3 shocks have six settings within each selector switch setting and the ride control module adjusts up or down using the VSS signal.

Anyway, I just figured you would need this bit of info as I don't know if it matters all that much if you mix valving front to rear. I'll say this much for the new valving, it makes performance a usable ( to me anyway ) option on the road vs just a track use setting. The OE performance settings was all but unusable unless the road was glass smooth, IMHO.

I bought mine at this place:

Oh, forgot this. I kept my OE shocks as someday I may send them to Bilstein for the rebuild. I know a guy that did this and it was north of $450.00 plus shipping and they didn't even put the new decals on or repaint them. Oh, he also went for the groove for coil over spring cup while they were at Bilstein. The OE configuration does not have the groove for a coil over set up.

Thanks Tom, this was very helpful, and at that price of $179 is the lowest I've seen for new front fx3 shocks. Really appreciate it.

So it wouldn't matter, as far as handling goes, that fronts will be new fx3's while the rears are original? I'm just speculating that the rears are stock since the dealer didn't say anything. Or should I replace all 4 corners?

Gary, I'm going to be honest and tell you I do not know the right answer to your question.

The reason I replaced mine with only 22k on them was they were floating more than I thought that they should. Did I do the right thing? I don't know for sure except to say no more floating over undulating roadways at speed. Another Z brother advised me to do all 4 even thou my mileage was low, the shocks were 15 + yrs old & he said just do it!

If it were my car, yes I'd do all four. Yea, the $800 was a big swallow! However, I notice the improvement in the damping ability of the new vs the old stuff.

Something to keep in mind if you do the r&r yourself. Mind the instructions in the FSM. Pay attention to the shock gear installed height specification!

Fair enough Tom. I'll just wait and see what condition the rears are in, and will take it from there. Thanks!
