Re:

Those are NOT IROC-Z wheels. They are Z-28 or RS wheels. IROC-Z's came with 16's, not 15's.

Incorrect

Standard IROC wheel for '88, '89 and '90 was a 15" wheel. The one shown is in fact the standard IROC wheel for 1988. '89 and '90 used a 15" version of the available 16" wheel. 85-87 came with 16s standard, and they were available in 88, 89, and 90, but were not standard equipment.

The mark is the foundry identifier.

Those i believe are the z28/RS wheels as stated earlier, the same set came on my 84 z28, my 85 iroc has the 16's and these are the 15's that were available on some years..................

Re:

Here's a shot of mine. They are factory Iroc rims. I'm running 1in spacers on the rear. They have 245/50R16 all the way around. They rub slightly in the front at full lock if I hit a bump.

Ditto. The 'rear' wheels were previouly mounted on the front while the 12" B-body brakes were on the car. After switching to ZQ8 spindles the rear wheels moved the the rear axle with adapters.

Yes, they are the Z28/RS wheel, and they are the standard IROC wheel for '88 as well. I should have made that point in my previous post, which was to dispel the common notion that IROCs all came with 16" wheels. The 89/90 15" IROC wheels are pretty scarce these days.

here are mine,
I have an 8.5 GN rear, and so I need a 1/2" spacer in back, and a 1"spacer up from, for my 245/50R16 tires.

this picture is from last year, where the wheels were gold still...

the wheels have since then been polished and painted charcoal black, and look something like this...
