I know several people at the track that have ran the OS Giken twin plate clutch. Considering the cost of this clutch set up if you plan on making a lot of whp/wtq and/or plan on your Z seeing track then the OS Giken will fit the bill. It is a great clutch for the coin spend as it has very smooth engagement and less vibration comparing to other clutch set ups. The OS Giken clutch is streetable though with close to OEM feel. It depends on what kind of clutch feel you like? How do you plan on using your next clutch? I personally like a more aggressive clutch as far as petal pressure and feel go’s. I really liked the Competition Stage 3 and Stage 4 clutches with a billet steel flywheel from AAM Competition. Do your research and drive someone’s Z or drive with someone in their Z to get ideas about what clutch set ups you may like.
