Since the mileage was over 108000km, I had the clutch replaced and at the same time I asked Nogami Project to do the work and have them install a sports flywheel. (The sports clutch line has been installed before.)
I have driven about 250km since installing it, and compared to the stock flywheel, not only does the engine rev up better, but the way the engine speed drops is also excellent. (If it is normal, the speed decrease will take a little longer.)

If you blip when dropping the gear, the rotation will rise and the rotation will drop quickly! It feels very good.
In this work, we installed a high cam. I also replaced the parts around the suspension, so once those parts are broken in, I'll be able to increase the engine speed even more, so I think I'll be able to drive even more comfortably.
(Sorry, there is no photo of the flywheel, and the photo is of the used clutch and engine.)
