So I just bought a 89 Camaro Z28 with 305 and has the IROC decals and IROC rims. Front and rear bumpers don't match the car color, they are faded blue compared to the rest of the car. I knew it was too good to be true so I really didn't believe the dude that I bought it from. I checked out the RPO codes and it didn't have the Z28 code which clearly told me its NOT an IROC. It has 16" IROC rims, codes show it should have 15" rims. It has the DX3 code meaning it should NOT have decals, and it has IROC decals from the 85-87 era (black on bottom, silver on top) which is another red flag, if they did it right, the black should of been on top.

This is just from doing some homework online. So im gonna have to take off the decals because I'm not gonna drive around with IROC decals if its not even an IROC lol.

So its definitely a Z28 but not a IROC lol oh well.

 

Shouldnt you have checked all of that before purchasing? You paid for something that it really isnt!

 

No Z28 RPO, but its def a Z28?

 

It really didn't matter to me if it was an IROC or not. I just wanted T-top v8 lol I only paid 1700 for it. There were a couple other codes showing it had Z28 options. Ive only had RS camaro's in the past and all I wanted was a camaro with a V8 and t-tops lol if its a Z28 then great, if not, then oh well lol

 

Im on this forum to figure out things about my car and help if I need it. If your willing to help me figure out what my car is, then I would appreciate the help.

 

Check the rpo codes in your center console and Z28 should be present if not its a rally sport. FYI a base model iroc could be had with a L03 tbi engine and 15 double stripe iroc wheels, fog lights, wonder bar, FE2 suspension. Check the engine compartment for 2 black iroc specific braces, one goes from the passenger hood bracket to the cowl and the other goes from the passenger shock tower to the lower frame rail. If those are missing you got your self a fake lol
Good luck buddy! When i was in this cali gen car club i ran into idiots like that all the time!!! Many would claim they had a iroc when its just a plain RS anyways those dumb kids voted me out of there lousy car club lol Screw it!!!

 

FYI there is no such thing as a Z28, its either a Rally Sport or Iroc Z!
No dis respect buddy just throwing out facts to you

 

Yea it doesn't have the Z28 code. Ive never had to find out about if its Z28 or IROC models so this is all new to me. Ive done some homework online to see what RPO codes meant and whatever. That is all I needed to know if 89 had Z28 or not. Thanks for the help guys.

 

in 1989 if you had a z28 you had an IROC.

 

Okay. Thanks

 

85-87 had the rpo of z28 & b4z to be an iroc. 88-90 just had to have z28 to be an iroc.

 

you may not even have the original arm rest lol. so check the vin under the windshield, and check the vin on the rpo sticker in the glove box

 

This is incorrect. In 1989, there was no IROC-Z RPO code. You had an RS or a Z28. All Z28s came with the IROC-Z appearance.

 

Those are not Iroc specific. My 82 and 83 Z28's had both of them.

 

In those years they are iroc specific!!! If i was talking about the early Z28's i would have mentioned that buddy.

 

Vin matches the glove box. No biggy lol I got another RS then. Im gonna end up stripping off the decals and put the correct badges on the car. Thanks for everyone's help.

 

There was no Z28 in the years of 88 to 90 just the RPO code Z28 that triggered the iroc z appearance package!!! Like i said no such thing as a plain jain Z28 just Iroc Z and RS!!!!

 

Hey a 89 RS is one sweet car bro!!! I have one my self and it was a decent runner in stock form! You can upgrade it later anyways so don't think you got ripped off cause you got a lot of car for the money you paid.

 

Yup I loved my 89 RS I had, this car that I just bought reminds me ALOT of the one I had, but this one has the V8 which makes it a WHOLE LOT better than that 2.8 V6 lol

I don't think I got ripped off, I think i got a good deal. I talked the guy down from 2200 and got it for 1700. It just makes me mad that someone out there was stupid enough to try and make it something it wasn't and totally did it wrong lol

 

Please stop spewing incorrect information. From 1985-1987, there were two options, the Z28 and the Z28 with the IROC-Z option package (RPO B4Z). In 1988, Chevy reduced the model lineup from 5 different Camaro models to two, the Sport Coupe and the Z28. You did not go into any dealership and order an IROC-Z, you ordered a Z28. The RPO for the IROC-Z in 1988-1990 was the Z28. You could purchase a Z28/IROC-Z as base as previous year's entry level Z28s, or as loaded as previous year's top level IROC-Zs.

People come to this website to be educated and you keep speaking incorrect information. Please know the answer before you respond. If you don't know an answer, please ask. That's what we're here for. Your statement above makes absolutely no sense when you state that there was no Z28, only the Z28 RPO. If it has the RPO Z28, then it's a Z28!!!

 

Hey !CamaroDave, are you sure you didnt buy your car from this guy?


https://www.thirdgen.org/forums/hist...4385-iroc.html

Seems there is a lot of IROC faking lately...

 

I know what you're saying, and for your purposes you are right. But technically the RPO code is "Z28", and it automatically triggered the IROC package. It helps to think of the IROC package as an "upgrade" to the Z28, and then after 87 feature creep just let all Z28s get the upgrade package... or parts of it depending on how well-optioned the car is.

As we all know, you can get an Iroc with some really, really low level options so the appearance package itself isnt really worth worrying about in the big picture.

 

Sure I am not gonna argue with you, i am fully aware its a Z28 but the finish product emblems, apearance package says Iroc z!!! Not Z28 but Iroc z!
Who was talking about the 85 to 87 models??! Not me! I was talking about the 88 to 90 Iroc z's and Rally Sports that were the only two models, and not the 5 previous models that chevy consolidated for the 88 model year! I also know that in the dealers brochure has only two models and the iroc z is a stand alone model not a upgrade off the z28 like it was in the previous years. I know exactly what i am talking about and maybe you should stop nitpicking my comments over such a petty thing. I expect a moderator to be a little for tactful with his words, so if you don't like my comments than band me!!! But i stand my ground!!!

 

Thanks!!! I was fully aware that a Iroc is a glorified Z28 with several levels to choose from, and RPO Z28 triggers Iroc z. At least you were cool about ,and i respect that. All i wanted to do was help this guy figure out if he had a Iroc or a RS but instead i triggered the RPO code "Cat fight" with scott

 

The only way to stop the rash of fake IROCs is to actually pursue charges against some of these sellers for fraud, which is exactly what it is. They are selling a misrepresented item, in this case an automobile. It's the same as someone trying to pass off a classic V6 Camaro doctored up as an RS/SS clone. If they represent the car as anything but a clone or replica, it's a crime. Unfortunately, until people are willing to press the issue, it will keep happening.

 

Fraud? Maybe, or the seller might actually think it's an IROC because the owner previous to him put IROC stickers on it. With used cars, it's the buyer's responsibility to verify the car before he hands over the cash.

 

Why do you keep insinuating (without explanation) that the non B4Z IROCs are just an "appearance" package without "some of the upgrades"? What specifically are you talking about? My FSM clearly says that RPO Z28 for 1990 is the IROC Z Option, not just a Z28. You keep implying that the later ones aren't real IROCs. What upgrades are missing?

 

Nope that's a little ways from Grand Rapids, Michigan lol. It might of been my responsibility to check it over but Im not a guy that has to have all original and be precise with details on cars. I fell in love with the car so I bought it lol it really doesn't matter to me that its not an IROC because I knew it was too good to be true. I never fall into those kinda deals lol

 

If I was looking for a certain car and had lots more money to buy one with, then ya I would definitely do my homework and make sure its 100% accurate. In this case, I wanted a Camaro with T-tops and a V8 that RAN lol and I found it for a good price.

 

Well we found out it is in fact an RS, so I appreciate all the help and sorry I caused so much of an uproar on this issue. Lol Thanks guys

 

The difference between an IROC and a Z28 in earlier years was basically wheels and a different paint scheme. I think the reg Z28s didnt get a wonderbar either, since that was to my knowledge only a necessity due to the wider tires (as far as GM was concerned at least).

After 88, the base z28s with the L03's, and LG4's and F41 and open diffs and highway gears etc... they were all "IROCs" just like the G92 L98 cars. Was just saying that the individual options on the car make more of a difference than the sticker on the door , since the IROC-Z badging didn't necessarily mean it had the good stuff inside. You still had to have an IROC to get a TPI engine (from 88-90) and all the good performance options, but you could also get an IROC without them, and even without the IROC wheels apparently as Scott Moyer schooled me the other day.

A little more poking around and it seems like any engine option you could get in a Z28, you could get in an IROC, and anything in an iROC could be found in a Z28. So it really does look like the only difference is the wheels and the wonderbar and maybe some weird obscure combinations and permutations of special options. In 85 and 86 a Z28 could get G92. in 87 it was for IROCs only. And then after that it's all a wash.

Mostly an appearance package at the end of the day i suppose, but it does get really confusing year to year with the silly subtle stuff GM did back then with the excessive option levels and weird combinations.

 

I was talking about 85-87 to help distinguish the difference between the Z28 and the IROC-Z. Most people believe and state that the Z28 went away in 1988 and returned in 1991. You said it yourself in post #7. You then said it again a few posts later. I'm not nitpicking your posts. I'm doing what a moderator does and verifies that the information being given out is accurate and not BS. I was very tactful in my first response to you, but you continued to say incorrect things.

Why is it that every time someone disagrees with a moderator, they throw out the "ban me" comment? That's just being stupid!! Do you guys really think that moderators on TGO are power hungry and can't be reasoned with? You've obviously been on too many childish boards if that's what you're used to prior to TGO. Grow up guys. We can all learn from each other. The OP asked about his car, so we need to provide him the most accurate info we can. That's what the History forum is about.

Dealer brochures and documentation are not always correct either. GM has documented in many places that the 350 TPI engine is the B2L. This is incorrect. GM engines start with an "L". They outsource document writing and many things get misdocumented. A brochure referring to the model as an IROC-Z is not accurate. It would be like referring to a blue car as the blue model. The IROC-Z was appearance from 1988-1990, not a sub model.

afremont, I never said that the non B4Z cars aren't real IROC-Zs. I said that they aren't an option anymore. They are still Z28s with the IROC-Z appearance. All Z28s now come with the standard IROC-Z options. Prior to 1988, all IROC-Zs came with 16" wheels, upgraded suspension, tighter steering, etc. The Z28 from 85-87 did not. The '88 Z28 still came standard with 15" rims, with 16" as optional. You got bent out of shape when I said that previous years the IROC-Z was an upgrade and the newer 88+ cars could be had as basic as the earlier Z28s. The 88+ cars could be as basic as was available in 1988 to include the 15" rims, the small V8, cheap seats, etc. The majority of everything else is now standard. Granted, you could get an 87 IROC-Z with the LG4 and cheap seats, but it still came as an upgrade option on the Z28.

 

The easiest way to state it is thus: All IROC-Zs are Z28s. Not all Z28s are IROC-Zs.

 

Exactly, an iroc-z is an "international race of champions" Z28

As stated from 85-87 you could buy a Standard z28 or an Iroc-z28(each having option lists to choose from)

From 88-90 ordering a z28 automatically got you the iroc styling No additional rpo was need to verify it being an iroc but they still came in various options

91-92 Iroc styling was not an option hence no iroc wheels or decals

The z28 never left as all irocs are z28's

 

Exactly. In 1988 Chevy realigned the Camaro available models and pared it down to Sport Coupe (standard with Z28/IROC style ground effects) and did away with the Z28 as a separate model, combining it with the IROC-Z and lowering some of the available options on the base IROC-Z to distance between the top model. The 16" IROC-Z alloy wheels became optional, with the base 15" 5 spoke Camaro wheel becoming the standard. All received the Z28 RPO code, but the B4Z code was retired. This did not make the IROC-Zs from '88-'90 "lesser" IROC-Zs, it just reflected a change in RPO coding. You could still have a fully optioned 5.7L L98 TPI IROC-Z that was every bit as decked out and performed as well if not better than the earlier B4Z cars. Just as in 91-92 you could get a B4C that was mechanically identical to a 91-92 Z28 (themselves identical to the earlier IROC-Zs, save for having gone to speed density TPI), but was badged as an RS.

My point is you're arguing semantics.

 

its okay happens all the time. its usually pretty entertaining. lol.
