Yeah HICAS is already locked out, and I think it's an R32 thing to not have diff bushes, there was another similar thread not long ago about that... I've got alloy cradle/subframe bushes on the way, thank god, since the car is driving like a VN at the moment!
I'm weighing up my options still - since I'm poor and can't really afford to replace all the individual components, I'm trying to get away with just doing what really needs to be done right now.
