Os giken tr2a

Quicksilvers

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.

This will be going into my G37 Sedan. Plans are daily driving and few track days. Not going to lie I’m a very spirited driver. I had a clutch masters 4 puck in my Sentra can’t be any worse I’m guessing. I have purchased the RJM Pedal and upgraded Master cylinder as well. I have only driven the Southbend stage 3 in a friends Z and I wasn’t a fan.

Select your clutch set up also based on if your Z will ever will or will not see forced induction? Do you plan staying naturally aspirated? I have seen the Southbend clutch set ups stand up to track duty and street duty they are durable that why people run them on their Z. On your G37 that is a smart move to upgrade your CMC. Seeing that the OS Giken series clutch set up will support 570+ FT/LBS Torque you could get away with the Grand Touring Series or STR series clutch. Even though the STR series clutch is lighter if you plan on more street duty I would consider the Grand Touring series clutch but they are both excellent choices.

Down the road I will eventually go A2A SC. I looked into the Southbend option and have driven a local Z with that set up and wasn’t too impressed. I already purchased the grand touring clutch but the Vendor went MIA on me, when I reached out to OS Giken they recommended I don’t go with the GT series as it’s not suited for the track. I don’t heavily track my car but I do plan on participating in a few events during a year. Essentially I’m looking to bullet proof the clutch set up and this is what I came up with lol. I hope it all works out.

If you plan on the A2A SC Kit in your future and plan on your Z seeing track duty then yes the OS Giken STR series clutch would be best suited for you. Definitely do your research before doing business with any vendor and make your own decision from there. If you have the opportunity to have track time in your Z go for it you will enjoy it! I had good experiences with the Competition stage 3 and stage 4 clutch from AAM as they held up to track abuse quite well. The best of luck with your new clutch set up though.

Clutch came in, build looks great I’ll make a review after break in and few more miles experiencing it.

Is the flywheel made of steel?
