The Hyperpro springs for the Z are a different part number again from R and X. AFAIK the R springs will also be too long for the Z and they are also a different start and finish spring rate as the R is quite a bit lighter.
From what I can make out none of the Hyperpro springs are interchangeable between the three XTs. They all have unique part numbers.
