I recently bought what I was told was a 1987 Firebird Formula, however, every nut and bolt and screw has been removed from the body and interior. The motor, trans, rearend and suspension are intact. He said it was a factory borg-warner 9bolt discbrake posi, which I can physically see is true, but he also said it had factory ws6 suspension, and I have no idea how to prove that by looking. What sets it apart from regular suspension. Lemme know. Thanks in advance.

 

sway bars. 36mm front, 24mm rear. thats pretty much it.

you have to measure them, or eyeball it. the rear will be about 1" the front about 1 7/16.

 

The ws6 package also had a quick ratio steering box. If you look closely at one of those steering boxes it will have a "Z" on it. Plus, I think all 87-92 Formula's came with the WS6 package. Also, try to look for the RPO list thats probably on the drivers side door.
