They are na skylines there will not be much hurting going on . A Smart thing to do would be to get gts-t struts for the front, which you would get nice 4 pot caliper brakes etc. And for the rear get the complete gtst diff disk to disk, then you would get lsd. You could probably get that in total for around 1k if you look around (IE forums of people wrecking their lines, MrMayfem , Hyperdrive, Dsturbd are also some other sobs that carry quality gear cheap) the labour to change these parts over would be cheap enough you will also get enhanced handling and breaking.
