It revs up smoothly up to high revolutions.

● Mounting parts: Sports flywheel

Although it still has the character of a Roadster (the original parts are also lighter), I replaced it in order to improve response that is not typical of a sports car.
It is difficult to remove the transmission from the ND, so the labor cost will be about the same as the cost of the parts.
It's a tough decision whether to wait until the clutch is replaced, so it's not a high priority, but I'm sure it will be effective.

As a result, the P70 engine, which had a score of around 5 points, rose to 85 points.
There are almost no disadvantages.
The engine revs up smoothly up to high speeds, and the engine braking is now stronger. I'm very satisfied.
