@boon @Joker yep drift car things, if you redrill (and reamed to correct taper) the track rod pick up point about 20mm-ish inwards towards the hub you can pick up a noticeable amount of steering lock, nothing too crazy but definitely helpful when sideways. I assumed so, they help on the track but I still have some spare untouched knuckles for the road.
That BF is owned by a guy called Wes, he has FabicationWorx in Tuakau, he's using FC rx7 front knuckles, which pick up even more lock than redrilled subaru knuckles, he has even made his own nissan rear end conversion kit (diff and hub carriers). The wagon isn't currently legal, I think its just waiting until he has the time to get it done. He actually welded my cage for me, really great guy.
I have spoken to him about this briefly before, he was very helpful, I just haven't had a chance to catch up with him properly recently (life, work, university work, lockdown etc). Like I said, I'm just after any little bits of advice anyone out their may have. Just so I have a better idea of what I need to ask about before I get on the blower to a certifier.
