SPEC stage 3 clutch

[nissias]

Hi there.
I have received my brand new SPEC stage 3 clutch for my car. Unfortunately Fidanza did not produce the aluminium flywheel I was planning to fit with the clutch kit so I cancelled the order with them. Now I am looking to buy an aluminium flywheel from CLUTCH MASTERS. They recon they need 3 weeks to manufacture after payment is all cleared up. I want to buy from them but is there a chance that the SPEC clutch kit won't fit with the CLUTCH MASTERS aluminium flywheel?
