It's slightly confusing at the front though as the pad kit is quoted as being "front left" because it is the same part (pad set) as the XTR which only has a left hand caliper (due to the XTR preceding the Z by four years, and they never changed the part/kit numbers info in 2008). The kit will do one caliper only. Ignore the "front left" bit. The pads are the same both sides on the Z at the front, so you just need to order two sets in order to do both front calipers.

So you need to order:

2x FA181R (front sintered)
1x FA208TT (rear organic)
