Hey there, I did a search and couldn't find what I am looking for.....I have a set of '86 16" iroc-z wheels on my car, which is a '91 with rear disc brakes, do I need to use the factory wheel spacers that come with the wheels or are they not needed?? I have them on there without the spacers now and it looks correct, but is it better to have them on?? it seems to me that the factory studs aren't long enough (at least to my liking) to run with the spacers.....are the spacers for drum brake cars?? Thanks for your help in advance.

 

Yes (though I had them on my disc brake car).

thanks james....I guess then I'll go ahead and sell them to anyone that might want them......It looks like it's in the right spot without them, and I run 255-50-16 tires...so it fits in the wheel well good...

 

The .187 spacers were installed after the change from aluminum to steel drums in 86. I had them on my 87 IROC and when I went to disc rears I sold them. GM stopped putting them on or it was a hit and miss until the stock ran out. Not a important part.
