IRS face-to-face dimensions, drum/disk?

[ByStickel]

I'm working on an upgrade for 510/610 IRSs and I can't seem to find the exact drum face to drum face (wheel mounting surface) width for the stock set-up.

 

Does anybody have that?

 

Am I correct to assume that the most popular disk conversions alter that dimension only slightly?

 

Thanks!

The thickness of the wheel mounting surface of the 200sx discs I have is 7.45mm. That's all I can provide this second.

That's a start, thanks.

OK so here's a chain of logic you can choose to reject.

 

280zx track width is 53". 280zx wheel offset is 0, so teach width is also wms.

 

According to Datsunfreak, 280zx rear end is 2.5" wider than a 510 wagon. So 510 wagon is about 50.5" wide.

 

Since 510 IRS swapped wagon owners never seen to complain about wierd offset issues, we can assume that the wagon rear end is essentially same width.

 

So in closing, 510 rear end width IRS WMS is 50.5"

I'll trust, but verify, that logic (;  Thanks. I'm sure that's super close, if not dead-nuts on.

Please do verify. I always mock people who just take my word for it. I make things up. :)

 

Here's where Datsunfreak referenced the comparison.
