Just a quick update, i got around to machining out my discs the other day, which was all nice and easy, and then bolted them up to the hub and mocked it all up on the bench on Saturday.
Firstly, the caliper with spacers:

Then all mocked up on the strut:

I love compressed air for many things. Including operating rattleguns to lock up hub bearings so the wheel doesnt spin, and pushing pistons out of calipers so that they the pads clamp on a disc 🙂
Not going to be an easy caliper adaptor to make though:

Back there near the disc is the caliper adaptor mount, and almost 35mm away is the caliper mounting face:

Ohwell, should be a good challenge.
In other news i popped a wheel apart too while i was sick, should be easy enough to clean up and reassemble without disturbing the wheel halves seal:

Thats about it, as i said, not looking forward to making that caliper bracket.
Arrrgh, this new caliper adaptor setup is going to be a sweet pain.
This is a stock AE86 strut and hub with FC caliper with an S13 disc, which according to DBA has a 49mm overall height.

This is a RA40 strut and hub, with FD caliper and S15 disc, which according to DBA has a 54mm overall height.

Now that sits a hell of a lot more than 5mm closer to the strut, and im not sure why. Looks like a whole bunch of measuring with verniers is in order.
So i was really worried about the LCA not clearing the disc, and being forced to rejig it all. In the end i neednt have worried… too much:

LCA clears the disc, just. It actually sits within the disc for some of the distance, which isnt really an issue at all. But it does make building the caliper adaptor harder.
I also testfitted the V4s over the top, and breathed a massive sigh of relief when they cleared:

But only by just again:

That gives you an idea of how much the center clears, or more precisely how close it is. Remember that the rim bolts onto the center around those points.
And it doesnt clear by much:

That pic also gives you an idea of how hard the caliper adaptor will be to make. Should be loads and loads of fun. I remember seeing a caliper adaptor which Linden at RoadRunner Fab did for BigPerm and so i might see if i can borrow that to model mine off.
Also as RESON8 correctly predicted, the caliper pins are too short:

Marcus is being a champ and sending the longer version over though.
