IROC suspension

Did 89 IROCs all have the same suspension, or were there different levels?

You could check your RPO tag if it is still intact. Certain suspension packages are listed as RPO codes.

You could check the springs tags if they are still present. You can physically measure the diameter your of swaybars.

All these things should give you some knowledge of your '89 IROC's suspension.
