Hello, I'm here to claim my prize for finding the ZX struts with the different angle to a 510.
The more I google my C32 strut conundrum (see my other post in suspension) the more I see folks claiming these don't exist. Yet I also see people saying their camber is f@&ed after fitting ZX struts. So here's my proof that there is a difference. Had to drag these inside and use some leftover wallpaper behind them because the lighting's so terrible in here.

As you can see, the 510 strut tube (the rusty one) is at a very different angle to the ZX one.
Part # to prove it's a ZX strut:

Now when I first looked at these in my other thread here, I thought the 510 spindle was at a different angle than the ZX one relative to the base where the ball joint attaches. However, I didn't notice the small unmachined area shown - as it turns out, the spindle angles may actually be the same relative to the balljoint mounting area - they may not be also, I don't have anything to accurately measure it and the phone doesn't like focusing on the shiny areas.

HOWEVER I also noticed that Byron and others have been measuring the angle of the strut tube relative to the flat area on the bottom of the strut, assuming that the ball joint mounting flat will always be perpendicular to the strut tube, when in fact it definitely isn't on some of them.
Therefore it's the angle of the spindle relative to the strut tube that should be measured. This, I think, is where people get the idea that the difference in angles is a myth.

It makes sense when you think about it - If Nissan were going to change the tube angle, then logically the base would have to be machined at an angle to correct the ball joint angle to keep it in the same spot, otherwise it might be possible to over-articulate it.
This also makes me wonder if it's not the ZX struts that have differences, but the 510 ones. I'm aware there is an early and late 510 strut, same with the ball joints and steering arms. Unfortunately I don't know what year the the 510 strut I have here is, and there are no numbers I can see stamped into it either.
I talked to a mate here who lives and breathes S130s and he doesn't think there are any variations. Perhaps some re measuring of people's strut stashes is in order.
The IDx 10 concept is based on the 510 in the same way that the urinating I was doing last night was based on a 30 yr old single-malt scotch.
