i know that from 85-87

the exterior color of z28 was 2 tone colors (different ground effects than the rest of the car)

and iroc was one color,thats what i read every where .


but i see alot of cars that have 2 tone color especially
read/silver , and they have iroc decals out side and
inside on the dash-board like this on on the link,

so did the ever make a stock Iroc with two tone colors?

 

No.

That's an interesting car. Could be an Iroc with the 2 stripes removed and the ground f/x painted, or it could be a Z28 with the multiple stripes removed and the Iroc stuff added. I'd be inclined to say it's an Iroc with painted ground f/x because there were fewer 87 z28 convertables. But then again, it may not even be a 87.
But like the other guy said. No Irocs were 2 tone. I've seen alost of people just throw on IROC rims, decals and badges and try to pawn it off as an IROC.

 

It's not a factory vert. It's more than likely a Z28 that's been converted by ASC from a dealer. The dash badge states that. It's nothing special.

 

ya i know its a custom job,i put it as an example
becausse i saw another one like it with 2 tone
and woth IROC-z28 on the dash and on the door,
so isnt there a way to differintiate z28 from iroc
"Visually" other than the colors?

 

Wheels, decals, fog lamps/grill, louvered hood. The IROC is a bit lower. It has a wonderbar. The headlight pockets are black.

First and foremost, third gens are old and it's difficult to tell whether it's original, repainted, restriped, etc. The info we furnish here deals with originality only.

That being said, the answer to your question for 1985-87 model years about visual differences is:

1) Z28's came in more exterior colors than the IROC-Z. So if it's one of those colors that wasn't available on the IROC-Z, it must be a Z28, i.e. 1987 dark blue metallic.

2) Z28's of some colors, bright metallic blue for example, came with a tri-colored blue "Z28" emblems whereas a bright metallic blue IROC-Z's "Z28" emblems were tri-colored silver.

3) Z28's were all painted with silver, gold or charcoal ground effects. IROC-Zs were body color.

4) Z28's came with a four-color stripe. The bottom color was always black with the remaining three being similar shades of silver, gold, gray, red, or blue. Some Z28 exterior color combinations had an optional striping color. For example, a white Z28 with silver rockers came with silver striping with red striping as an option. The IROC-Z striping was two-colored: silver/black, gold/black or red/black (1985 only).

5) The tires/wheels were different.

6) IROC-Zs were all equipped with fog lamps. For the Z28, fog lamps were not an option in 1985. They were a $60 option in 1986. In 1987, they were not available separately but were included of the 1SC Option Package #3.

Pictured is a 1987 bright metallic blue Z28. It is a perfect example of what a Z28 looks like. With a gray or black interior, the rockers were silver and the striping was blue (no silver striping available with this color combo in 1987, only 1985 & 1986).
