man had to rescue this from a couple pages back.
As for the brakes, you could just get the rotors skimmed and some new pads. Those rear calipers look to be the same funny ones from S110 silvias - so long as you have good pads in the rear you shouldn't need to do an upgrade. There is/was an S110 at pick a part in auckland with what looked to be brand new rear brakes (new rotors, pads etc), its a shame you're far away.
when I first got the Eterna new rotors were going to be minimum $300 each for the front, I ended up just getting them machined for $30 and fitted heavy duty pads and it pulls up mint.
It's looking good on those wheels
