Billstein shock absorbers? Was this an option? I thought I read somewhere that the Billsteins were part of the IROC package or was this just an 1985 introduction thing?

I know the '85s had the Delco/Bilstein units, but I can't find any info as to whether or not the post-'85s had them as well.

Bilstien struts/shocks were std equipment on
all IROCs (even my TBI 15" wheel car) and were not an option for other Camaros.

Wow thats great...those things last for a LONG time. I remember reading in Grassroots Motorsports Magazine (great mag by the way, if you ignore their Honda fetish) that Bilstein's still have almost 98% of their original effectiveness after 50k miles of normal driving. To me, that makes up for their ridiculous replacement price.
