FYI, you can get coil-overs for the rear from Troy Ermish Racing.
As far as cutting struts, You'll need shorter inserts, so I'd say find the shorter inserts you want first, then cut the housing to fit. Also, in case you didn't know, the 280ZX struts are shorter already. And they use 10" vented disc brakes with bigger calipers/pads. It makes a HUGE improvement in stopping ability. And with a few slight mods they will bolt right up.
