this might not be the correct place to post this but i was jw if i had an iroc or a z28. i was 100%confident that it was an iroc until i realized that they had irocz emblems that went on the bumper. my emblem is z28 along with the rocker panel emblems. when i bought it i was told it was an iroc and i had no reason to doubt it. it has iroc caps on the wheels and dash but i think the dash and console were swapped out. theres no iroc z decals on the door because it was repainted so i was just wondering what the deal was on that. my camaros an 86 so maybe idk they didnt make the iroc emblem until anfter that year. anyway if anyone could shed a little light on that it would be appreciated, thanks.

decode your vin number.

The bumper and GFX emblems changed from Z28 to Irocz in 88 when all Z28's became Irocs. The VIN number won't tell you anything, since the LB9 was available on both the Z28 and the Irocz. If you want a really good clue that the car is truly an Iroc and the SPID is missing, check the tire placard in the door jam. If it shows 245/50VR16's you know it's an Iroc sinze the Z had 15's.

thanks drew after you told me that the iroc emblems didnt come out till 88 that makes me pretty confident its an iroc. i have the the same tire size too. btw what's a SPID?

iroc stangs

im thinking its probaly a iroc-z. the spid i belive is on the bottom side of the center console lid.

Check the RPO's for B4Z.

Check for a wonderbar. If im not mistaken, IROC's got them, not Z28's.

My Formula, every 6cyl Fbody I've ever owned, my 86 T/A, they all had wonderbars... I think one or two of the ones I've sold had them when I sold them... Granted I added them, but it's not a very clear indication.

The SPID is the label in the center console from 84-91.5 and the trunk glovebox in 91.5-92. As James mentioned B4Z indicates an IrocZ on 85-87 cars. 88-90 just have Z28.

Service Parts IDentification label. Introduced in 1984, it's a sticker about 2" x 4" listing all the RPO's related to the car. Located in the center console until about mid '91, then found in the rear storage compartment. The VIN on the SPID must match the one on the car to be accurate.

At least you guys have build sheets and other indications on your cars.

My car has no indication of what it is. I know that its at least a z28, but the VIN says its an 89 IROC Z.

The Build Sheet has been removed from the car somewhere along the line, as well as the tire placard on the door jam.

I think it is more like an 85 Z28 than an 89 IROC Z, but no biggie to me anymore, I still love it how it is

EASIEST WAY TO TELL IF AN IROC. IROC's came with k-member braces. I have yet to find 1 person ever attempt to duplicate an IROC by adding these. EVERYONE buys wonderbars, stickers, decals, emblems, wheels etc etc. BUT nobody ever adds k-member braces to a non-iroc...or at least I have yet to ever find one that had the braces but wasn't an IROC.

Look for these
Spohn K-Member Braces
on the right and left side of the engine right near the frame rail and k-member. Located on the front corners of the k-member, facing the front end.

Take care.

That the pieces are IROC specific is doubtful--at least in my little pea brain. Check the following link for some insight:

My 84 V6 Camaro with the F41 suspension had the braces. So did the 86 Firebird base model I parted a few years back. And the 86 T/A's I owned, yep they had the K member braces too. I can't remember if my 83 Camaro had them, but then it didn't even have a rear sway bar. An Iroc should probably have the braces, but I wouldn't say any Camaro with the braces is an Iroc.

I think the lower control arm bumpers are different with 16" wheels.

JamesC

iTrader: (5)

There's a steering stop on the A-arm that differs depending on what size wheels the car was equipped with. The bumpers are apparently different as well.

Bumper, lwr cont. arm (1985-87 W/FE2) (1988-91 W/16" whl)

Did you notice those with IROCs saying they had both (Even you said it). I never said they were IROC SPECIFIC. I said an easy way to tell its an IROC is it will have these braces, in which case is both in which is stated in that thread you gave me. If it has 1 its probably not an IROC, is what I got from that thread.

To be a valid indicator it needs to be something specific to the car. If you can find the part on other models, then the car could be something else. Since those brackets came on various other cars, they aren't a valid indicator. Things like RPO codes, VIN numbers, factory markings are usually missed. Most people aren't rebadging a car to sell at a higher price, they rebadge the car because they want an Iroc and they've only got a RS or a Z28.

Essentially this is what I was trying to say above. No argument here .

+1 for the wonderbar.

My 86 Z28 did not come with a wonderbar and the first thing I look for to validate that it is indeed an iroc is the wonderbar underneath the front sway bar. You will also notice a subtle front ride height difference between a Z28 and a real IROC.

A lot of the IROCs I have seen have a thin cowl brace from the passenger fender to the cowl, door decals, and the IROC-Z dash emblem. The steering gear box is the performance box, and the spring rate is going to be really stiff.

Someone would have to meticulously replicate all these details to make it a true clone.

According to my Parts and Illustration Cat. CD, the Brace, Fdr, Rh to Upr Cowl Pnl (14074745) is listed 82-91 for Camaros. No reference is made to particular models.

There's another piece as well. In 82-86 the CD refers to the Z28, but thereafter, 87-91, that designation is dropped and the part number is the same for all years: Brace, Whl Hse Pnl Reinfor-RH, 14045394. Interesting.

To me the funny part is seeing identically equipped cars, and one will have the braces and the other doesn't, when both are basically the same car. Sometimes there's no rhyme or reason why some cars got a support and another didn't.

You've also got people that see something on another car and just have to add it to theirs just because... It's not really 'safe' to assume a car is an iroc because it has XXX or YYY brackets, braces, emblems, etc. Fortunately most people doing clones don't care enough to do most of the changes necessary to really build a clone.

thanks james,the badges on my car all say iroc and the only one different is on the dash,its z28 iroc.

JamesC

iTrader: (5)

The badge is Z28 with IROC-Z, in smaller letters, beneath. An old pic below, but you'll get the idea.

that be it

Iroctopless

Your '89 IrocZ is normal to have this (here's mine) . . .

Remember, on the IrocZ . . . Z=Z28. All '88 to '90 IrocZ's still bear the Z28 RPO and the badge.

Brettpaterson

Hope this thread is still alive. I just bought an 86 and it just says Camaro on he dash where everyone else has Z28. Maybe a new dash? I don't know.

I'd call the thread a dead one but it's not anymore I guess. From the one picture you gave us, it does look to have the iroc cues. Did you check the SPID label as the thread suggests??? Does it still have a label? Now your car could have been dressed up to look like a iroc OR its just a different emblem on the dash. They pull off real easy. Being you gave us one picture that doesn't show much and no other details about the car, ie engine, year...it's going to be tough for us to determine what your car really is.

That's a nice looking car interior. It looks like you picked up a car with the deluxe interior, my 86 Z28 has a black interior with a similar texture to it. The steering wheel and horn button also look like a Z28/IROC wheel. Look through the RPO codes, look for the rocker and bumper emblems to say Z28, look to see if it has the wonderbar brace under the front sway bar, look at the side of the door on the drivers side for the sticker and read the above comments.

To be honest, it looks like someone popped off the Z28 badge on the dash and replaced it, maybe the seller kept it. The door sills are usually black or red on this color interior, it looks like they have been changed as well.

Brettpaterson

I literally just bought it yesterday and buy I don't have it yet. Got to make arrangements for someone to drive it home for me. Here are some more pictures though.

I looks like a good car. Some tlc and it'll be a great car. There are a few things that aren't quite right..like the fog lights are aftermarket..but it's more that likely an iroc with the one badge a base model badge instead of iroc badge. When you have it check it for the SPID if it has one it'll probably have B4Z in it.

I don't think it' an '86. No 3rd brake light is mounted on top of the upper hatch glass. 1986 was the year the chmsl was federally mandated & f bodies got a clunky looking plastic piece stuck on top of the glass.
