Was FE2 suspension standard on all IROCs? Was FE2 available on other Camaros? Z/28s?

 

Yes.

Only IROCs from '85-'90.

 

Thanks so based on research on the site, FE2 in 1989 includes:
-36mm (hollow) front stabilizer, 24mm rear stabilizer
-548lbs (BZW) front springs and 131lbs (NNL) rear springs.
-High effort steering box 12:1 (12:7?) ratio 2 1/4 turns lock to lock
-Delco/Bilstein shocks in the rear and special struts up front (some factory variance on this).
-Wonder bar

Did I miss anything as compared to FE1 or F41?

 

Well, Charlie is mostly correct. FE2 was also available on the '91 and '92 Z28s, and B4C cars. Not all later Z28 came with FE2, but it was available to them as an option.

 

Yes.

 

Were there IROCs from another era besides '85-'90 that I am not aware of?
Thanks

 

No, but as Scott mentioned available on Z28 from '91-'92 and B4C. I was trying to be specific on my answer, but I can see how it could be confusing.

 

Did I miss anything on my list of 5 items that come with FE2? I see a few conflicting notes on the steering ratio?

 

I thought the IROCs came in 34/23 and the 36/24 was strictly for WS6 and 1LE? That has been my experience on the 85-87s but not sure on the 88+.

 

based on my research on this site the 88-89 had a 36mm hollow front and 24mm rear sway bars. Earlier IROC were 34/23.

 

My ‘89 IROC FE2 came with 36/24.
My ‘91 Formula WS6 came with 36/23

I never rely on info, always mesure them.
