I am guessing that the photo is not the actual drum? If it is it won't work. The drum they are showing is five lug. Lately I've noticed that e-bay's filtering of parts has gotten a bit too lax.

I know these are available for Mini's, but I have no idea if those would fit a Midget. The ones I've seen for minis all have an inch thick spacer build in, so you may have tire backspacking issues if you went with one. You'd get a small reduction in rotational mass and unsprung mass, but compared to the unsprung mass of the rear axle and diff that part would be unnoticeable. I don't think the extra cooling would have any real effect, the rear brakes on these cars just don't do much work.

There are two 'vintage' options, both made by Minifin. The first is an alloy drum, standard size. The other is the Super Minifin with a built in one inch spacer. I run the standard Minifin drums on my A40 Farina's rear end (same basic set up as a Midget). Some of the modern repo drums do not have a metal contact surface for the brake linings.
The Midget and the Mini share the same bolt pcd, four inches.

thnx all for your comments. I wondered about the five lug holes in the pic but then the ad says for Sprites and Midgets. Someone told me JC Whitney carries these as well. Can't see them as a great advantage anyway.

Your midget year already has front discs. I see no real advantage. Now, if these drums fit the older cars front & rear with original drum brakes an advantage may exist for a lot of stop and go or braking on a long hill steep declines.

thnx for the thoughts. Yes, I wasn't looking for any great increase in regards to brake fade but thought for the price I might pop for a pair. Strange that the add would specifically list Sprites and Midgets and then provide a pic of five lug bolt holes.

Yep, that's what I do even with the race cars. I guess all this was not as common knowledge as I thought, but I have seen Alfin brake drums on Spridgets since I was in my 20s, and most of them were on race cars. Kinda one of those deals where you turned every stone to gain a a overall advantage, so nothing is never too much. Totally not necessary for a street car.

If I were going to spend any money on upgrading the rear brakes, I would just convert to discs with Nissan parts. It's not terribly expensive, and would mostly be for looks anyway (which is why I'm thinking about it myself, lol).

Can you forward the part number or a link please? I've looked for this type,with integral spacer, for a reasonable price for any years Mainly for looks since I'm using 7spoke alloys. Minifinsareoutragously expensive for the few miles I drive my Moggie.

Gene, I guess you saw Hap's post above. I think you can find them in JC Whitney's catalog as well but I have not tried them.

Gene, just checked Whitney's on line catalog and didn't see any finned brake drums but you could call them and ask.

I wouldn't bother trying to get such a specialized part from a general place like JC Whitney (besides, the photo is of a cast iron drum which wouldn't fit a midget in a million years).

If you are looking for cast aluminum finned drums to dress up your rear brakes, you can get them from minimania.com (or from any mini specialist), they have reproductions of them ("minifins"winking smiley with the spacer for $170/pair, or the "name brand" Superfins on sale right now from usual $300/pr marked down to $120.

Note that the finned aluminum rear drums are all modeled after the original Cooper S drums, which means they had the 1" spacer cast in. You will have to machine off the spacer to use on a square arch Midget because I am not aware of anyone making them without that shape.



From the minispares website:
"designed originally by J.V Murcot as a direct replacement for the "S" rear drums they will also fit the rear of any Mini or Sprite/Midget"


Cost comparison: stock, cast iron midget rear drums are only $30 each, from Mini Mania.
