99 spec rims - 2 different castings

The 17s will go square if you make a habit of driving over objects or into holes.
Haven't heard of different castings, wheel part numbers for version V and VI don't seem to have altered either with no A or B suffixes. 2lb difference would be over 10% weight change too, which seems a bit unlikely to me. The BBS 17s are about that much heavier however - and there were several changes there depending on date of manufacture and paint for different models.

What, if any casting numbers on the rims?
Have some sets that have that ridge in the barrel from memory, but they might just be the rears, have to check the fronts.

Rz were BBS not the cast mazda versions.
The "channels" from the spokes running into the mounting face, I don't recall seeing those before now.
Edit: do think the ikea scale is off, around 8 and 8.5kg on corner weight scales ages ago is my memory too

I think it's the same detail in one respect as the first one, with the enclosing ring around the lug holes. As said, fairly sure it has the barrel, same as the second with the reinforcing though.
I'd have to double check, last use was just dyno wheels a couple of years back.

Finally had a look at the ones here today and there's both varieties. It's a bit of a gamble with the Japanese fad of putting efini bits and pieces on everything 15 or so years ago, but the mazda centre caps seem to belong on the long channel variety and the efini on the full contact mounting face type.......if the tyre fitters haven't done the old switchero at some stage.
