| Product Descriptions | This lightweight flywheel is created especially for use with NISMO single-plate clutches. It is not just light: it provides the ideal weight to guarantee even engine rotation in the low rpm range.The use of high-strength, high-quality chrome molybdenum carbon steel reduces weight by 60% to 70% compared to standard flywheels. Used with a NISMO clutch cover and clutch disc, the package provides a total inertia weight reduction of 80% to 85%, reducing torque loss at low speed while improving response at high rpm. When used with a solid metal disc, it provides a more direct feel than a dual-mass (damper equipped) unit. At the same time, the same ring gear chamfering process as for standard parts has been used to ensure smooth starting through improved engagement with the starter motor pinion gear.

Nice watch
Color: Green/Green
Very happy with my purchase, rated the purchase with 4 stars due to the band being very stiff, holds doesn't line up to fit wrist properly, don't recommend for seniors to purchase, very difficult to put on.

Feels cheap, not good for old eyes.
The watch seemed to work good. But it felt cheap, and I was looking for something with better illumination and easier to read. I ended up returning it.
