Willwoods most likely, easily available and a lot of folk talk of their lightness/unsprung weight (to go with their "heavy" aluminium wheels), but there are more older in-keeping mods that less people favour but work equally well.
Rear brakes less so, its not really needed, a good drum set up working good well with quality shoes (I will be running project µ all round). The older way was going 280zx rear calipers on the back.
