the main problem with the r31 strut is that the hole in the base of the strut that locates it onto the steering arm is a different diameter to anything else,ie stanza.the way around this is to weld up the hole & machine it to fit.this is a job for an experienced welder & machinist.you have to change the springs to smaller diameter,& probably do a height adjustment conversion at the same time.the good news is these struts are the shortest bodies,& they have 10 inch ventilated discs standard,& it seems bigger discs will bolt on.this last bit is something you'd have to confirm with someone like errol (feral),however.you also have to start running front wheel drive offset wheels,or at least later model wheels.you can then go to r31 rear discs,which is what i'm looking at at the moment.only problem i can see is how to hook the hand brake up.
