I was wondering if anyone knew the right answer for this question.

I have a 1987 IROC-Z, at least that is what I am led to believe, the RPO Code Sticker on the inside of the console says

B4Z : IROC PACKAGE

All of the other codes point to an IROC as well. She has 4 wheel disc, 16X8 wheels, 5.7L engine, and all the proper badging, but as you know if someone wanted to sell an RS or SC as an IROC they could make the necessary changes. The one thing that has me wondering is the badging on the rear bumper. It says Z28, the rocker panels (behind the front wheels) says IROC-Z. I thought I saw an 89 IROC with the IROC-Z rear bumper emblem. Did they change this in some year or is my car a Z28 with IROC pieces? What is a sure fire way to know?

Just wondering

From 1985-1987 it said z28 on the bumper. From 1988-1990 it said IROC-Z on the bumper. Very easy to tell if your car is an IROC. Only IROC's had 350's in them. So go look at your Vin #, if the 8th number on your vin is a "8" than it is a true IROC

My 89 IROC has IROC on both the rocker panels and on the bumper. I have seen cars with Z28 on the bumper and IROC in other places that I know were legitimate and done like that at the factory. I think they mixed z28 and IROC badging to varying degrees each year. I wouldn't worry about it.

....I think they mixed z28 and IROC badging to varying degrees each year.

Sorry, but this is wrong.

To answer the original question, IROC-Z's from 1985 thru 1987 all got Z28 badges (sides and rear). That's because the IROC-Z was an option on the Z28.

In 1988, the IROC-Z became a model in and of itself (and continued thru 1990). These IROC-Z's got IROC-Z badging on the sides and rear. GM was so cheap that they did NOT replace the Z28/IROC-Z dash emblem from the 1985 - 1987 run and retained it on the 1988 - 1990 IROC-Z.

Ok...I am fairly certain my car is a true blue IROC.. this is important to me as I am keeping this car. Iroc's are going to be collector items in the future (due to the fact they were only made from 85-90...I guess all of the F-Bodies will be collector items if they never bring them back. Anyway, my VIN's 8th digit is an 8.. 5.7L . Cool about the badging, even though mine contradicts a previous post... Z28 on the rear, IROC-Z on the sides.

Check out my RPO Sticker..

Willie hit the nail right on the head, but didn't fully comment on what you originally stated...

You said the bumper has a "Z28" emblem, while the sides have "IROC-Z" emblems? Something is wrong there...

Either they ALL should have "Z28" emblems (1985-1987 models), OR they ALL should have "IROC-Z" emblems (1988-1990 models)....I can't possibly believe they would come mixed and matched out of the factory as suggested above...

Therefore, I am guessing that somewhere along the line, an owner of that car replaced some of the emblems...

If you do infact have a 1987 (as your VIN should disclose), all 3 emblems should say "Z28"...sounds like the ex-owner changed the badging...

hummmm...I am not sure anymore..My brother owns a 1986 Z28 and his ground fx emblems are Z28, mine look like they were made for the IROC-Z emblem (they don't look like they would have had Z28 there). I know for a fact that my car had a front end collision at some point in its life (the rad support are welded in) .. I am thinking the ground fx's may have been swapped... either way my RPO codes indicate B4Z- IROC Package.

Is there anything in the VIN that would indicate IROC vs Z28??

Well I guess that settles it...my car must have had newer ground fx put on her...I know that she was crunched on the front...I guess the ground fx was cracked as well and they were replaced with '88 ones.. no biggy. I know that my car is a true IROC due to all the other things..

I wouldn't say so. All fx panels from 1985 thru 1990 are identical. That includes RS's, Z28's and IROC-Z's.

Why do you believe the panels were replaced when the emblems (only) can be removed and replaced?

Willie

Because if you look at the side grnf fx that has Z28 on them and then you look at the ones that has IROC-Z you will notice that the g-fx is sorta notched to fit the Z28 (like if you removed the Z28 badge you would still see the outline of Z28) same goes for the IROC-Z... so that is why I think my side g-fx was changed to one that had IROC-Z

your car has the 88-90 gfx on it, as 85-87 said z28 with the iroc sticker on the door.

88, the iroc became its own model. therefore, the badging said iroc-z in place of the z28, and moved the iroc sticker to the back of the door.

Mirsiro427

Actually, they have a rectangular depression where the emblem goes. You could make up an emblem that said anything you desired, so long as it was the proper dimensions.

okfoz

I know that in the factory, strange things happen. I have a friend who back in the 80's bought a Tarismo brand new from the dealer, The funny thing was when they got home all the interior panels said Daytona.

These emblems could have been simply mixed up from the factory.

I personally owned an 83 Riviera that had the 84 Tailights. My car was one of the last ones made that year and it was possible that they started using the parts too early.

It's like the 50 or so 1986 camaros that got the L98 350. According to many publications, the 350 was not even an option till 87. I believe these cars were meant to be 87's, but were produced before the change over to the new model year.

Anything is truely possible, If your center console states IROC, then congrats, as far as I am concerned you have an IROC. Thats where the proof of the pudding is, that little tag.

That car you have there is exteremly rare for one notable reason: T-tops & the 350.
If you have an 8 for the 8th didget then you have one very collectable car.

Rumors & books that I have seen is that combo was only available for 89 & 92.

I think it is very safe to assume you have a true 1987 IROC-Z, judging from the information you have stated and seeing the picture of your car...everything seems to check out..

I am with you on the fact you believe the accident your car was involved in caused the GFX to require replacing...unless the repair was done by a dealership (which will replace parts with the proper stock equipment), the repair garage may have ordered the wrong year GFX, it all sounds plausible....

You can certainly (and I would) get the original GFX (either from GM or a junkyard), to keep your car as original as possible...GFX are pretty cheap, unless you need to have them painted...

Never the less, good looking car!!

I guess I could get the Z28 emblems and put them in place of the IROC-Z instead of getting all new g-fx...that is if they will fit in the notch,

I kinda like the badging on the side as IROC-Z... but if it isn't suppose to be there then I will remove it...

Could I just get a Z28 emblem and pop out my IROC-Z? I am getting my car painted in the spring and if the Z28 emblem won't fit in where the IROC-Z goes I will look for a set of '87 g-fx over the winter

Hey man, it's your car, if you like the "IROC-Z" emblems on the side, by all means, keep em there

I don't think the "Z28" emblems will fit in the "IROC-Z" grooves...I could be wrong, but I'm pretty sure..

For a cheap fix, I've seen people fill the indents with glue, and then slap a new emblem over that, making them stick out....it works, but it doesn't look quite as good..and certainly isn't stock..infact, for hardcore IROC fans, it may lessen the value of the car...

Anyways, if I were you (and again, I'm not, hehe) I would find some 85-87 style GFX and have the body shop throw em on for you

Okay guys, this is the last time I post here. I'm going to set the record straight again.

All ground effects from 1985 thru 1990 are identical, including the shape of the depressed area on the side pieces. The depressed area was designed to accomodate the 1985 (first year) Z28 logo. GM was so cheap that when it decided to go with the IROC-Z badging in 1988, the logo was designed around the already designed depressed area instead of retooling new ground effects to accomodate a "longer" 5-character name (IROC-Z). That's why it looks slightly short, in comparison to the door decal -- because the depressed area was originally designed for the Z28 lettering (three characters as opposed to five).

There is no way a 1987 model year would sport a 1988 IROC-Z emblem. When it comes to visuals, GM was very keen to introducing "new" graphics/visuals on older year run cars. In other words, you'll never see a 1988 IROC-Z emblem on a 1987, nor will you see 1988 IROC-Z wheels on a 1987. Other examples: You'll never see 1985 ground effects on a 1984. You'll never see 1987 seats in a 1986. You'll never see 1991 hood blisters on a 1990. Get the picture?

As for 350 t-top cars, they were originally available together in 1987 on the IROC-Z. Although this combo is considered desirable, it is not that rare.

Ok...this will be my last question as I am pretty sure I have a real factory IROC (with everything everybody said and what my car is equipped with, and RPO codes and all that).

So my question is...if I were to get a couple of Z28 gfx emblems from say ThirdGen Resource or GM would I be able to pop out the IROCZ emblems that are in my gfx now and put the Z28 emblems in without a problem?

I probably won't do this now ( I like the IROC-Z emblems in gfx) but it would be good to know for the future when these cars become more valuable...I would probably just buy the emblems now and shelf 'em for a few years

On my '87 IROC it has IROC emblems on the G/FX and the rear bumber cover. Does this mean someone took a z28 and made it look like an IROC?

Looks that way...if it is an 87 then it should have Z28 on the rear bumper cover and the side gfx... you sure its an 87? What does the VIN decode to??? Run you VIN on the VIN Decoder and it should say for sure if it is an 87 or not... in 88 Iroc's had IROC-Z as badging back and sides.

Its '87. 2 ways I can confirm it.

2) In '88 there was no LG4

Well if it is an 87 then somebody switched your emblems to make it look more like an IROC... it should have Z28 on the rockers and the rear bumper.

Look at the tire info decal in the drivers side door jam. As far as I know? Only IROC's came with 245/50ZR16 tires. If your tire data decal has this tire size. Then It is an IROC. My '86 IROC-Z was in an accident,which damaged the drivers door. When I replaced the door,I cut this portion of the original door out (along with the VIN decal) in one piece. That is now my only proof that is is an IROC-Z.

Ghigman3

That would be a little hard considering that I have only 1 sticker and that is a VIN# from the right quarter panel and the VIN# in the window which do not match but they both say its an '87 with an LG4. Other than that I have no more stickers.

Ghigman3

Heres an interesting little bit of info I found at another site(http://www.iroc-z.org)

Under their FAQ:
Q. Were there any body changes in the IROC-Z?

1 of As. 1987 has the third tail light moved. It is embedded in the spoiler this year in the rear spoiler instead of the back hatch window. There appears to be a mid-year change for 1987. The early models had the 1985-1986 style of emblems whereas the later style says IROC-Z on the rear bumper. Door decals and lower ground effect emblems are the same as 1985 and 1986.

so that's why my "Camaro" badging on the ground effects was so ugly, it was smooshed. now i have z/28 badging, but it's still an SC.

86IROCTHD

ok to who ever said that the #8 for the engine code is a true IROC is wrong.... in 85 which is the 1st year or the iroc the iroc's had an F for the engine code.... the z28's had an H..... and the other way u can have proof is to look at the repo sticker in the console or in the rear locking thing and compair vin numbers.... or go to your local GM dealer and see if they can look up your vin number..... dont know if u can do that but should..... and not all iroc's came with disc brakes for all 4 wheels....and up to think 88 all the IROC's had Z8 badges on the g/fx's and then an IROC door sticker..... but not positive on that.
