My GF got a 91 RS and got a set of 91 Z28 rims and I know we need some sort of small spacer between the rim and drum. What size is it? Thanks

 

matt:

i'm pretty sure they're 1/4 inch spacers.

 

Yup, 1/4"

 

This is goona sound stupid.But whats the reason for the spacer
I dont have them on my 87 iroc.Do you need them?

 

I have heard rumors about 2 reasons.

1) The spacer prohibited corrosion between the rim and drum, so they wouldn't rust together.

2) The drum brakes gave the rear 1/2" less total width over the disc setup. The spacer brought the rim out to the correct width.

 

can i just use 5 hardened steel 1/4 washers?

 

Um, NO. You have to think about the contact area of the rim surface to the drum. If anything run the car without the spacers until you get a set.

If you are that bad off, I think I have a spare set that I will let for cheap. PM me if need be.

 

The spacer was installed on Iron drum brake cars to maintain the same distance when the Aluminum drums were discontinued. Not that big of deal if you decide not to use them. Most were lost over the years when cars changed hands.

 

Oh... NP thanks lol I'm not cheap I'll run and get a set. Can I use a 1/4 universal 5 bolt set from Mr Gasket?

 

The Mr. Gasket shims will work just fine.

 

1/4 huh? My spacers are pretty thin, about a 1/8 or 1/16 maybe. I kind of wondered why they bothered.

 

When I had mine they measured .187 or 3/16". I forgot to add in my previous post that they were also added to be used with the 16" wheel & tire package.
