S15 flywheel

[JDMonster]

Is this the factory flywheel? I want to purchase a lighter flywheel but am not sure if it should be as thick as this one. This was on the car with a dual disk Gmax that I got rid of for a exedy organic clutch kit. 718617186271863

Is this for a 6-speed? Doesnt look like an S15 dual mass flywheel to me, look more like S14 or S13s.
