Default S5 n/a engine, S4 n/a trans... which clutch?

I may be coming up on a S5 n/a engine in the future to swap into my S4 n/a. I'd like to use my S4 n/a transmission, but I'm not sure which clutch to use. I've noticed that all the clutch kits I've looked at have different part numbers for S4 and S5. I'm guessing it has to match the transmission, since I can't see how there could be a difference on the flywheel side .

You would use the clutch that worked with the flywheel. So you will want an S5 clutch. Still trying to envision the differences. I know the disk itself is the same between the two. The S4/S5 use different bolts for the cover, but I'm pretty sure one will bolt to the other.

^^Yep. You go with the flywheel setup on the engine.
