This is no doubt a great idea. I would highly appreciate it if you'd
write a DIY.
I don't remember any 'rear TT control arm' discussion if we had one,
however I do remember the former platform TT (8J) had the same
rear control arms as Golf and A3 used to have. The increased width
has been realized by using wider (aluminium) wheel carriers:

That said, I'd bet you could do the same on a current MQB Golf or A3
if the wider track don't cause fitment issues.

Hi. Yes I can put together a DIY on the subframe, CSS swivels, SuperPro LCA and H&R ARB. This is hopefully going on the car soon.
Regarding the TT rear parts you are correct @breaking badly. I ment the alloy bearing housing.
Any info on how much wider the TT part is?
