My IROC dose not have a wonderbar, it is an 89. I heard that all IROC's came with them. Is that true?

 

Are you sure it's a real IROC? If it is, it should have a B4Z RPO code. Plus parts tend to be taken off these cars. I had an IROC that I took the wonder bar off of and put on my bird. When I sold the car I gave the guy the bar, but now it's on a 91 RS. It didn't make it back to the IROC.

 

Yes, It has Z28 : MERCHANDISED PKG, SPECIAL PERFORMANCE which is the RPO for an IROC

 

What size rims? There is an ongoing discussion that IROCs equipped with 15" rims didn't get the Steering Brace (aka Wonder bar).

 

B4Z : IROC PACKAGE

 

My 89 Irocz orginally equipped with the 15 inch Iroc style rims did in fact get the wonder bar!!

 

B4Z was optioned on top of the Z28 for the IROC package. 88-90 the RPO for the IROC package was Z28

 

No way. Every IROC got the wonderbar period. Forget that 15" garbage. They're also saying that 15" IROCs also didnt get the 'Z" steering box.

 

It was probably taken off or maybe just never put on.

 

Get a Global West Steering Brace. They are better than the IROC wonder bar anyway.
