R34 Subframe Question (Sorry, GTSBoy)

[Kinkstaah]

Hello.

I have a R34 GTT and because reasons, I need to maintain stock geometry.
However, I can change the geometry.

I have a few questions.

1) Can I get a non HICAS subframe and bolt everything from the GTT subframe into said subframe?
2) What parts of said subframe determine whether the rear shocks can be fork or eyelet type? I do not want to change from current fork type because I would like to keep my coilovers.

My ultimate goal is to convert my current car into having stock rear toe arms I can set with an adjustable whiteline bush for configurable toe.

Answers to inevitable questions: I have a HICAS eliminator kit already. I can not use this.
The diff has to come out because reasons anyway. The tailshaft is removed for reasons anyway as is the exhaust. There's not much in the way of removing the subframe.

I would also like to put every bush known to man into whatever subframe (i.e the R34 non HICAS one) goes back into the car. Is there a kit for this? I don't know the names of every bush that is on every site and this is quite confusing to me. I do have *some* bushes already. Can I re-use these?

I have pineapples, and rear camber adjustment for the current uprights in the GTT.

How much of this can be re-used?

OPTION 2:
Buy HICAS parts and put into GTT subframe.

Surely no one wants option 2.

I searched, oh god I searched but I'd like confirmation before I buy a subframe I can't use, or one that requires me to replace my diff, or axles, or coilovers or buy whiteline bushes I already own. I would much rather put HICAS back in than do that.

Non-HICAS subframe goes in.  You keep your uprights, which means you keep your fork type suspension units.  So far happy happy.

You need the toe control arm outer bush inserts (from the non-HICAS car, or preferably new) to replace the HICAS tie-rod outer balljoints.  Easy enough with the usual brute force and a press.

All bushes are otherwise the same and will swap.

So what you are saying is ultimately with having 2 subframes, I can create my own for joy and happiness and success. That is what I was looking for.

Does anyone do a "Hamburger with the lot" bushing kit? I do plan to provide the subframe + said bushes to a workshop with a press to do this. I noticed awhile back I didn't actually need more alignment settings than what Whiteline (etc) adjustable bushes actually offer.

So new bushes, enough alignment and better NVH and friendly with the legalities, kind of win win for me.
