Hey gang..

This is my 1st Post here...:-)

Recently purchased a 1987 IROC 5-Speed Coupe. Some of the RPO codes are: FE2, GM3, G80, G92, LB9. The car also has the Auto dimming rearview mirror, overhead console and power drivers seat.

How common are these options on a 1987 Iroc??

Thanks for the help..

Find a copy of the Camaro White Book. It lists the individual options and their production numbers.

 

FE2 - IROC-Z Sport Suspension
GM3 - 3.45 Rear Axle Ratio
G80 - Limited-slip Differential
G92 - Performance Axle Ratio
LB9 - 305 TPI

Basically, you own an IROC-Z with the performance axle ratio (G92). In 1987, the 5-speed and G92 received the 9-bolt Borg Warner rear axle assembly with 3.45 gears. The G92 is a desirable option in all years. Whether the 9-bolt is desirable is debatable.

The automatic dimming rearview mirror, overhead console and power drivers seat are included in the top-of-the-line option package, RPO 1SC. Unfortunately, GM never kept records of the number of option packages sold.

All in all, you've got a 1987 IROC-Z that came equipped with almost all the options available that year. This fact in itself makes your car more desirable than most for that year.
