what is the Bundt rim ET?
 

I believe that there are two different widths of Bundt rims, but whatever they are, the books seem to indicate that there are at least 3 different ETs for them:


25mm 30mm and 33mm.


Anyone know if any of these widths are associated with a particular ET ?

First, I suspect the numbers above are wrong if meant to represent wheel width. I know of three bundts:
1. One with about 6" width which weighs about 16#
2. There is another then that is about a half inch wider which weighs a bit more.
3. There is a 15"d. I believe which is very rare.

Looking at this pdf it doesn't show 33mm but only 30 and 25 offset for bundt rims. (w108 or 109 is not listed so I'm not sure)


from page 12 you have the listing for forged light alloy rims:

w123 and w126 rims by model:

From the wheel information tables this may be concluded:

14" Bundt wheels have an ET of 30mm.

15" Bundt wheels have an ET of 25mm.

Okay, I'll cry "Uncle"...

I don't know how to decode the following stock rim specification (from the Factory Service Manual) and if someone would be willing to clarify, I would appreciate it:

"6J x 14 H2"

While you're at it, LOL, what does the "ET" represent as previously posted in this thread?

A humble Thank You.

ET stands for the German word " Einpresstiefe" which is the depth of the offset as shown in the three attached rims, which look suspiciously like Bundt rims.

Following this logic, if the Bundt rims are 30mm positive ET, then that Means there's a lot of room inside to fill, perhaps with a spacer.

You see, I plan on putting these Bundts on a slightly lifted smart car.

Ahhhhhh. Yes, I see and now I understand.

Thank you for clarifying the ET for me. :)
