i have a stock flywheel and what appears to be stock clutch with some meat left on it in my garage. i have a s4 n/a and thats what it supposedly came off.
my clutch is slipping horribly.
would it be ok to just put the spare clutch and pressure plate in without using the spare flywheel or should i use all three components?

 

If you have a lot of meat still on there, sure. But you will have to resurface your flywheel. Otherwise it will be uncomfortable when you release the clutch for the next 1000 miles.

 

but i got the flywheel the clutch was seated on in the first place. so wouldnt be easier to swap flywheels too?
