Re: iroc????? or r/s rock

A 350 wasn't available in 1986. B4Z indicates that it's an IROC.

Re: iroc????? or r/s rock

Time to celebrate. Sounds like you've got yourself an IrocZ.
Maybe those of the Camaro unedcuated type at your workplace think it's not an IrocZ because the paintjob isn't correct for an IrocZ. The headlight buckets should be black to be truly correct. Looks like a sharp car though. I like the yellow paint on 3rd gens.

Re: iroc????? or r/s rock

Looks like a nice IROC-Z. Yellow irocs do look the best IMHO. The grill looks good yellow, but I would paint the headlight pockets back to black. I would also get the iroc decals and factory 16 inch wheels back on it, then she would look realy good. Great find !

Re: iroc????? or r/s rock

kinda odd it has a 145 speedo...I wonder if the speedo was replaced maybe?
Get you some iroc stripes and some irocz door decals paint your headlight buckets black and you will be back in business. And yes, the spot on the ground effect close to the front tires should say just Z28. The TPI z28 sticker did not come out until the 87 model year. Your going to enjoy that car. I had two 86 irocs.

Re: iroc????? or r/s rock

I don't usually like yellow IROCs simply because every single one of them I had seen had the painted faded or was trashed one way or another. The one you showed in your pic looks great! Now I can see why some people like yellow IROCs. It's an aquired taste.

Re: iroc????? or r/s rock

IROC-Z sounds like what import guys would use if TYPE R never became! Nothing special just a stripe package and wheel package big deal.

Is that what you would say about a GTA. Come on, we are all on the same page here. Let's not run down other members third gens. Looks like a great find to me.

Not really. Unless we are talking difference between a plain jane camaro.
A z28 its not that much difference. Like he said, stripes, wheels, painted buckets, iroc dash name plate,
a sway bar, and some bilstein shocks in the rear. Not much more than that.
If you can think of something im all ears.

Re: iroc????? or r/s rock

From the tech articles, in 85 the differences:

The new IROC-Z option was available on the Z28 and came with new 16x8 aluminum "IROC-Z" rims, P245/50VR-16 Z Rated Goodyear Gatorback tires, fog lights, new grill with CAMARO on front license plate panel, .5 inch lowered ride height, body colored valances, (ground effects) Delco-Bilstein rear gas shocks, special front struts, increased spring rates, special jounce bumpers, 5 degrees of caster in front wheel alignment, (up from 3.5 on Z28) 'WonderBar' front frame rail stiffener, special valving in the steering box for increased steering effort, larger rear stabilizer bar with stiffer bushings, IROC-Z exterior decals and interior "Z28 IROC-Z" dash badge, and a thinner two-color lower body stripe."

Most of these things carried over to 86.

The above echoes the info in the Camaro White Book.

AHHHHHHHHH the GTA ......... Just another Type R ......

fender vent delete
special seats
badges

but still retained the same basic shakes rattles and recalls as a base firebird. The two pace cars are the only f-bodies I think that are worth anything.

Alright I'm not trying to knock anybody's car here at all or anything. I should say your car is beautiful also I should also say I do prefer the RS look (probably why I like your's so much). But in reality who cares if it's an IROC or not with a little reading on this site it's pretty obvious it's an '86 IROC with a 305 (I'm guessing a little misinformation by a previous owner). But as I've said before the performance advantages the IROC had, I can't imagine are much of an advantage anymore (P245/50VR-16 Z Rated Goodyear Gatorback tires, .5 inch lowered ride height, 5 degrees of caster in front wheel alignment, (up from 3.5 on Z28) larger rear stabilizer bar with stiffer bushings) as these things are probably worn out by now and easily upgraded.

My point is if it's a Camaro it's a Camaro. IROC doesn't mean much right now since there isn't many of these cars at barret jackson (which is probably why most people want an IROC thinking it will be worth more). Again I don't want to offend anyone here but performance other than handling sucked compared to today's cars, (I have a 2001 grand prix with a 3800 that would kill MOST 3rd gen f-bodys). Just have fun with the car the only reason we all like these cars is because of the way they look and they are simple to work on but don't buy these cars for performance.

Hello hardon85!!

You mean to tell me that after having my IROC for 23 years, I shouldn't have bought it for the performance???

Where were you 23 years ago, you could have saved me a boatload of money!!!

23 years ago it performed pretty well........and still does!!!!



We all have a different perspective on performance I guess!!!

Yup but other than the fog lights nothing else really cosmetic.
The two cars handle and ride virtually the same you would not know the difference
from one to the other if you got out of one, then in the other. Not to start a argument on the IROC vs Z28 ect.
What the hell is a "jounce bumper"?
Is that some funky way or naming a shock obsorbing bumper?
Anyway, techno_1961 that is a cool find. You have any interior shots?
What are your plans for the car?

We'll have to agree to disagree on this one (If I understand correctly). If the cosmetics are removed, the following is particular to the IROC and its handling properties (.92g's in skidpad tests): ...new 16x8 aluminum "IROC-Z" rims, P245/50VR-16 Z Rated Goodyear Gatorback tires... .5 inch lowered ride height...Delco-Bilstein rear gas shocks, special front struts, increased spring rates, special jounce bumpers, 5 degrees of caster in front wheel alignment, (up from 3.5 on Z28) 'WonderBar' front frame rail stiffener, special valving in the steering box for increased steering effort, larger rear stabilizer bar with stiffer bushings...

Same exact point I am trying to make. Even RS VS Z28 VS IROC.

The three are easily cloned from one or the other, OR even the above additional parts and camber settings can be acheived on ANY camaro; the car body wise is the EXACT same car in all three. These cars are easily cloned looks wise just pick which model ya want. As far as performance, you are right on the money.
You can take a RS and upgrade some of the suspension, the brakes, some of the paint scheme and the car will be BETTER handeling than a stock IROC and will look the same or BETTER depending on how you paint it and finish it off.
Sorry for getting the topic off but I agree with hardon85

James, no harm done. I understand what you are saying here. But all the above really amounts to nothing monetarily. Read my other above post so you will see where I am coming from. I am not trying to knock the IROC as they have they're place and I have owned two IROCS myself, a Berlinetta, a Z28 and a 92 RS.

Re: iroc????? or r/s rock

i usually don't like yellow cars, but like the others said, that looks damn good in yellow. although i would change the light area back to black like they said, that would be a good looking car, even though it already is. I like it, nice car
