Hey,

Recently I had the need to do the clutch with no downtime. I am already running a Fidanza aluminum flywheel. The problem with this is that if yours is older, then it could have a 8.75" or 9" friction surface.

Now, if you have to do it with no downtime you need a insert. Mine was built in 2007 and uses the 9" insert. If you have a picture (like most people take at some point of their new/installed parts) you can tell what friction surface size you need by counting screw holes.

Fidanza PN / Diameter / Bolt Holes

228751 / 8.75" / 16 Holes
229001 / 9" / 18 Holes

Hopefully this will help in the future. Seeing as mine is 9" and was built in 2007, most of you will need the 9" version.

Thanks!
