I just aquired a 91 formula 350 top and I was going over the rpo list and it says it has FE2 and WS6. What is the difference between these?

 

Anybody? I know what the ws6 is but why would there be ws6 and fe2?

 

code fe2 is 30mm front sway bar, 24mm rear sway bar

 

I wonder why I have ws6 and fe2 on the rpo list then. That's wierd.

 

the fe2 is for the sway bars and the ws6 might be for the formula option...my iroc has fe2 for the bars and b4z for the iroc code....gta and formulas i think got the ws6 code for the extra stuff with the suspension.

 

but that is not the only thing in the fe2 rpo, it also includes an "upgraded" power steering gear box

 

i didnt know it included the upgraded sterring box....good to know. when i looked the fe2 code up it only gave the info for the swaybars.

 

Some of the threads I'm reading are saying that the fe2/ws6 combos have 36 front and 24 rear swaybars.Were they different from some of the earlier years?

 

I didn't know this until I went to the parts store to get a new power steering gear, there are actually 4 different ones on a 91 RS alone.

1. RPO FE1 w/ soft ride
2. RPO FE1 w/o soft ride
3. RPO FE2, F41, Z28 , 12:1 ratio 2 1/4 turns lock to lock
4. Race only - improved valving and quick steer

I will be using the race only unit on my 91 RS, but only because of all of the other suspension mods I have done.
