The FX3 shock can be rebuilt by Bilstein and they even offer custom valving for autocross or track use. IIRC, it's called "Morroca" valving and was developed by a CF member for Bilstein a few years ago.
Call Bilstein at 1-800-537-1085 and ask for Jack French in the tech department. You will find he's very knowledgable about the FX3 system.
Doug Rippie Motorsports has a custom controller for the FX3 system that uses a removeable prom. Proms can be burned to change valving rates between the three postions of the switch. You can have specific setups for autocross and a variety of track conditions.
There is a Forum member who makes a billet aluminum ring gear for the shock actuator. The factory gear is a plastic/nylon piece that gets brittle with age and when it cracks, the only option was to buy a new shock actuator. The electronic portion (a simple motor) hardly ever goes bad.
IMHO, the FX3 system was a great piece of engineering at the time. Custom setups like I mentioned can give you a great shock system for street or competition use.

What year are you looking at? If it is a 94 or newer I might be interested in front shocks. Doesn't even have to be good as I am going to send it in and have Bilstein rebuild.

It doesn't matter what year you get, Bilstein replaces the rod. SO you can build 89-91 shocks out to 92-95 spec.
