I was working on my friends Iroc the other day and I looked at his sway bars, they looked the same size as mine, if not smaller, it was a lg4 5 speed, I didn't have time to measure them, so I figured I'd just ask you guys, thanks

 

anyone, surely you know

 

The Iroc package consisted of monotone paint, Iroc badges, and suspension upgrades. The only time that I'd question this would be cars that came from GM with 15" wheels. The easiest way to check is to look at the RPO codes. FE2 designates the Iroc/WS6 heavy duty suspension. F41 indicates the mid level suspesion, and FE1 is the base suspension with front and rear sway bars. Earlier cars typically use various other codes.

 

thank you

 

My IROC Vert came with 15" from the factory and it has FE2 in the RPO codes. It also has the 36mm front bar and 24mm rear; I measured it with a digital caliper.

 

Does it have the wonderbar too??? My RPO sheet on my '88 IROC doesn't list any "F" codes for the suspension. It has the 15" wheels, large swaybars, but no wonderbar. I've been trying to figure out if it is missing or was never there.

 

Yeah it has the wonderbar. I can take a pic of the RPO sheet to show the FE2.

 

No need to do that. Thanks for the info, it certainly helps.

 

No prob. I kinda thought it was odd that I got the FE2 with 15" wheels anyway.
