I want to run a set of S5 rotors in my new rebuild but I was thinking about running a FD flywheel because it is lighter, will this have trouble mating to my NA transmission. All I have now is an S4 clutch and pressure plate, can I use these or do I need to buy the corresponding clutch etc. to the year of flywheel Im running.

Thanks.

The FD flywheel is the same size as the TII flywheel, so you will need a TII driveline to use that flywheel. FYI, the FD flywheel weighs the same as a S5 n/a flywheel (19 lbs).

I thought the s5 na flywheel weighed 22 pounds. Is it really 19? I guess I should've weighed mine before I put it on.

Mine weighed 19 lbs, i checked it on a scale.

ok then scratch the FD flywheel idea but can I use an S4 clutch/PP on a S5 flywheel?

Yes.
