I have an '84 Sport COupe and I'm planning on getting I-Roc ground effects with the scops like in the 89-92 models i believe. Can someone who has done this conversion before give me some pointers and some simple instructions to work from? Is there anything i should do or look out for so as to not run into too many problems? Thanks

Also, I need help finding a brand new I-ROC front bumper to replace mine.. anyone know where I can find one that would be greatly appreciated... Thanks a ton!!

The 89' Irocs had different ground effects than the RS models? I thought that only 91-92 models had a different ground effects.

MaineIrocer

your right i bileve its on the 91-92 years had the different one....

CbrasTsteLkChk

yeah my mistake, i wrote that post when it was late.. the years were 85-90 for the flat I-ROC ground effects and 91-92 for the scope I-ROC ground effects.

ANyways... any help with my original questions?

Pearl Jammzz

I really think they just screw off....I am 99.9% positive they will line up perfectly.

CbrasTsteLkChk

actually, they bolt on.

When you find a set there is 2 bolts on the lower side pieces. You will have to pull the interior sail panels to get to the back bolts and remove the plastic wheel wells to get to the front bolts. If you are gettin the 91 92 style ones you will also need the mounting rails. I was able to get mine off with a step bit on a cordless drill. You will need a friend with a welder or I suppose you could screw them on.On to the doors you have to pull the panels of to gain access to the nuts in the door. If it sounds like its takin awhile... it is and when you put em on it will take even longer to make em look right. Just dont get in a hurry. Good luck bro'

91-92 rs and z28 all had the same gfx

CbrasTsteLkChk

I believe that's correct for all the ground effects except for the front valance.

Diabolical

85-92 all have the same front bumper, but the rear bumper, rear 1/4 gfx, rocker and door gfx, and front chin spoiler are different 85-90 and 91-92. as far as doing the conversion, front and rear bumpers bolt right up in place of the old bumpers. the gfx, you will have to drill all the holes, and you need the support rails for the rocker gfx, then they will bolt right up. the best way to line up the bolt holes is to make a template from the mounting surface of the gfx with some cardboard, then use that template to mark the holes on the car. the front chin spoiler will bolt right up to the front bumper, but you will need to drill the holes for the fenders. 85sportcoupeto89rs did this conversion, i'm sure he would be more than willing to give some tips that he may have.

CbrasTsteLkChk

Thanks a lot. I just PMed him asking for some info.

badandy247

no what i said is entirely correct

89cmrodriver

yup badandy is 100% correct, and incase u didnt already know, there is no such thing as 91-92 IROC ground effects.

Pearl Jammzz

No such thing because all of them have the same ground effects? Is that what u are saying?

89cmrodriver

no, chevrolet lost there contract with IROC (international race of campions) So 90 was the last year, which was a short production year. 91-92 there was only a RS and a Z28.

85SportCoupeto89RS

Heres the actual name and year of the camaro ground effects.
82-84 Z28
85-90, Z28 and IROC also 88 sport coupe, 89 and 90 RS. All gfx were the same for all 3 models
91-92, Z28 and RS. All gfx were the same for both models

Ok onto the parts that you will need.

Front bumper from any 85-92 Z28,RS,IROC,or 88 Sport coupe. All of the bumpers for these models were the same, a 85-90 and 91-92 front spoiler will bolt right onto the bumper. No modifications needed to mount the front bumper on the fenders.

You will need a 91-92 Z28 or RS front spoiler.

You will need the 91-92, rocker panels, door fillers, rear quarter panel gfx for both sides of the car.

Lastly you need a 91-92 rear bumper. It bolts right on with no modifications. You can not use a 85-90 rear bumper because it has a slightly different design compared to the 91-92's.


Onto the next part, Mounting the gfx.
You will need a drill, a rat tail file to enlong gate any hole's if nessicary and cardboard.
Why cardboard you may ask? Its to make templates of the hole locations from any 91-92 Z28 or RS that is in your local junk yard. If you cant or there are no 91-92 z28's or Rs's in your local junk yard then you can make them from your GFX, that will give you a rough ideal of where the holes are located but not exact as actually using a car that has the holes in it. The way you need to make them is where the edges of the carboard lines up with the edges of the sheetmetal. I attached a pic of the 85-90 gfx holes which are about the same as the 91-92's.

For the lower spoiler you will need to make 3 slits in the bottom of the fender for the spoiler to bolt to the side of the car.

For the rocker panels you will need to drill 2 small holes in the fender for the gfx to be screwed on. You must make sure to make these holes small enought so the screws will be able to thread them selfs to the fenders.
On the rear portion of the rocker panel there is 1 stud, you have to drill 1 hole in the bottom of the rear quarter panel. All of the studs on the gfx's require wing nuts. You can get them from any auto parts house.
You can get away with not installing or fabricating the rocker panel gfx bracket brace. As long as noone steps on the top part of the rocker panel then it wont break. You can make some V brackets "I think I bent them to 135 degrees" that you must weld onto the body of the car. Thats what I did. I bent some metal and welded it to the car then I mounted the rocker panel and drilled the hole for the screw to go into the V bracket. Pretty simple to make and it server its proper function.

The door filler has 5 studs, you will need to drill 5 holes in the bottom of the door. Note you will need to remove your door panels to put the 3 wing nuts on the 3 inside studs and on each edge of the doo you have 1 wing nut.

For the rear quarter gfx you need to drill 2 holes in the bottom of the rear quarter panel.

If your as lucky as I was and have the base of base camaro's then you had no rear spoiler. You can do the same thing for any spoiler for the camaro's.

82-86 Z28, berlinetta, LT, Sport coupe and 91-92 RS spoilers are the same. Its a 3 piece spoiler
87-90 Z28, SC, RS 3 piece spoiler. It is bigger than the other style of spoiler and it has a brake light in the center spoiler.
91-92 Z28 High rise spoiler. You only have to drill holes into the decklid for this one to fit.


I strongly suggest that you make the cardboard templates. It will make the project so much eaiser to do.

Pearl Jammzz

SO you have to drill holes into the bottom of your door for the side gfx? And I dont fully understand the whoel thing w/ the spoiler.....are you taking about equiping a car w/ the 901-92 spoiler? Or about actually having to do sumthing to your stock spoiler/fin in order to have the 91-92 gfx on?

85SportCoupeto89RS

Yep, you have to drill 5 holes in the bottom of each door.


Yes, I was talking about adding a spoiler to an car not equiped with a spoiler. Like how mine was, if chooses to add any one of those spoiler's then he has the correct info for each design of the camaro rear spoiler. I did leave out the 88 sport coupe "shorty spoiler" they just dont look right for some reason + they are hard to find.

The spoilers have nothing to do with being able to mount the 91-92 gfx, it just serve's more of an eye pleaser to the whole appearance of the ground effects. IMO a camaro without a spoiler looks like its naked.

CbrasTsteLkChk, you should add a hawks 5 inch 3 piece spoiler on your car. They look kick *** you would need to make a template of the 82-86 or 91-92, 3 piece rear spoiler so you have the proper holes in the body for the Hawks 5 inch spoiler to fit properly.

Pearl Jammzz

So the gfx on the side are actually on the door? so it's not 1 piece like how my 89' rs is? So it follows the door....stays on it.

85SportCoupeto89RS

Heres a in progress pic of my car.

The white arrows point out where you mount the rocker panel gfx.

The red arrows point out the door filler.

The door filler gfx are the only things that are attached to the door. The rocker panel gfx are attached to the back part of the fender and the front part of the rear quarter panel.

CbrasTsteLkChk

OMG, this sounds hard as a mother! CAN ONE OF YOU COME AND DO IT FOR ME?!?! hahaha







I actually wanna get this spoiler:

CbrasTsteLkChk

What do you mean "slits"??

I don't get how the effects ATTACH though. How do they hang on the bolts? WOuldn't you have to put it through the actual effect to stay on? I'm so confused here.

Can you explain this bracket a little better to me? What's it for? why would i might not need it?

And lastly, what's the best way to make sure everything is straight and lining up correctly?

Pearl Jammzz

thatnx for the clarification 85sport.......I never noticed that there was a dif. piece on the 91-92 gfx, now I know, haha. Anyone know where I can pickup sum 91-92 gfx?

badandy247

for the gfx good luck they dissappear fast, you can get a new spoiler at www.spoiler2000.com just do a search for camaro they have them for like 160 and 180 with a third brake light

85SportCoupeto89RS

The 3 slits on the fender make it possible for the side of the spoiler to attach to the fender. There is a metal bracket that you put on the spoiler. It hard to explain but the spoiler has some excess material on the inside portion where that bracket goes. When ever you tighten down that bracket to the fender it compresses that excess material between the bracket and fender, thus holding the side of the spoiler to the fender.


For most of the side gfx they already have studs mounted on the inside, the only part of the gfx that you do put something thru is on the rocker panel's where the emblems are located. You have to use 2 screws to hold them on. So you dont have to put anything thru the gfx.
I attached a pic of my door filler gfx. The white dots are where the studs are located behind the exterior portion of the gfx.
The studs require these sheetmetal nuts called wing nuts.


You just have to bolt everything on and see if the contours of the gfx and body are alinged.


What it does is support the top part of the rocker panel gfx "the gfx that is just below the doors" when ever it is accidentally stepped on it will prevent the gfx from being broken. I crudely drew a pic of what it does. Basically if you can keep people from stepping on the top part of that gfx then you can go without this bracket. If you cant then you will need to get some metal and bend it to shape to fit the body and for the part that meets with the gfx needs to be level with the mating surface.

Pearl Jammzz

wait...I need sum more clarification. On my 89' RS I have ground effect already on. I have the five holes like u said already there w/ the effects attached on. Now since I already have the gfx installed, to get the new ones all I would have to do it make the holes on the door and the rest of the gfx would fit nicely?

89cmrodriver

if u have them then no drilling. just bolt them on

Pearl Jammzz

sweet, what about the metal inserts that goes inside the gfx...the supporter things. will those work in the new gfx?

89cmrodriver

yup, the only thing u might have to change is i dont remember if the 91-92 front gfx are slits or round holes? might have to make your round holes enlongated

Pearl Jammzz

Sweet, I am likin this. Now you said there is a part that actually attaches to the door.....would I also have to drill holes into my door to get this piece on?

85SportCoupeto89RS

You shouldnt have to do any drilling to the door. If I recall correctly, the stud locations were the same for the 85-90 and 91-92 door filler gfx.

Glue. Lots and lots of glue.

Lol, I put 1992 gfx on my 88 Iroc, and all the mounts were different. It was NOT fun!

Pearl Jammzz

How were they different? different type holes? different location? Care to further explain?

aaron7

iTrader: (7)

My gfx had mounting holes, the 92 ones had the bars that sat in the slits.

Pearl Jammzz

pictures?

aaron7

iTrader: (7)

I have only the pics before and after I installed them, none of the holes or mounting.

Pearl Jammzz

Well, on my 89' when you open the door......there are holes on top of the graphics on the inside, holding them on. Do the 91-92 gfx not have those? or do they have those plus other things?

aaron7

iTrader: (7)

They have those + other things. Least mine did!
