I just want to point out that the jerking feeling will most likely never go away even after new subframe bushings and such. That clunk you hear is the lsd working and that means the wheels are spinning at the same speed, but in a turn that means fighting each other. I run a welded diff and understand what you mean by the car being jerked around, but I would explain it more like a pushing feeling in the rear. Also both people telling you to go solid subframe have s14's in their sigs, but unlike them your s13 has a solid mounted diff so stepping up to solid subframe bushings will most likely increase how harsh the diff feels and possibly make it even louder. Sounds to me like you just need to get used to a 2way, but the subframe bushings are always a good idea.
