You mean the 1/4" inch ones? They came on the rear of my Camaro when I got it, used. I was told its to keep the rear rims and the rear brakes from corroding together. Or maybe to make the rear wheels stick out a bit further for a better stance. Who knows?

I have them on mine too. I just figured they were for clearance. As it is I have to use stick on wheel weights because there are pieces of metal that catch the weight and drag it arounf the rim. I need and adjustable bar to solve that I think.

According to the GM parts manuals and my own experiences, they only came on rear-drum cars with the iron drums. This is because the iron drums were thinner than the aluminum drums and the rear rotors.

yeah the funny thing is that the 16" wheels are labelled FRONT and REAR. When i look at the front wheels, it looks like they already have an intergrated spacer. The 15" 88-90 IROC wheels are interchangable, with no front or rear labelling, and they already seem to have little spacers already.

my 86 roc has aluminum drums and it also has the small spacers. i think it was an easy fix for GM to get the front and rear track aligned. do we all have the same sized spacers? (mine aren't 1/4", mine are more like 1/8") if there are different spacers, here is my theory. there were 3 brake options, disk, aluminum drum, and cast drum. GM probably didn't want to cut a wheel for each type of rear brake, so they made a universal wheel with spacers for each brake system. that is my uneducated guess.
