I installed it when I replaced it with a genuine rebuilt engine after an engine blowout.
This installation requires separately prepared parts such as a counterweight, but once installed it improves engine speed and makes driving more enjoyable.

It's not an extremely lightweight flywheel, so I didn't feel any difficulty in riding it or the lack of torque, so I was able to enjoy it with a feeling that was an added bonus to the original.
Since it's AutoExe, I don't think there's anything wrong with choosing it anyway.It's safe.
When replacing this flywheel, I use the company's sports clutch line and another company's reinforced clutch.
