Dramatically improved engine response and acceleration come with mild-to-moderate gear rattle, a trade-off typical of lightweight race flywheels. Heat-treated forging delivers strength and toughness, and induction-hardened ring gear teeth maximize service life. The one-piece construction reduces potential failure points and provides efficient, uniform heat transfer away from the clutch disc, eliminating warped inserts or loose ring gears sometimes seen on multi-piece flywheels. The flywheel is forged, CNC-machined, and dynamically computer-balanced for smooth reliability at high RPM, and is recommended for race use.\u003c\/p\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/9aea4a88ee91500c37a766fcb5c28a21.PDF\"\u003eWarranty\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/d856e10aab4787d29e6c192d62ac3288.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConstruction: Chrome-moly, forged and CNC-machined\u003c\/li\u003e\n\u003cli\u003eWeight: 10.6 lbs\u003c\/li\u003e\n\u003cli\u003eFriction Surface: 9.4 in \/ 240mm\u003c\/li\u003e\n\u003cli\u003eRing Gear: 108-tooth, induction-hardened\u003c\/li\u003e\n\u003cli\u003eSFI Rating: 1.1\u003c\/li\u003e\n\u003cli\u003eRecommended Use: Race use\u003c\/li\u003e\n\u003cli\u003eResurfacing Limit: Up to 0.040 in (1.02mm) of material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1991 Nissan Silvia K [JDM] 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1992 Nissan Silvia K [JDM] 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1993 Nissan Silvia K [JDM] 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1994 Nissan Silvia K [JDM] 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1995 Nissan Silvia K [JDM] 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1996 Nissan Silvia K [JDM] 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1997 Nissan Silvia K [JDM] 2.0L Turbo\u003c\/li\u003e\n\u003cli\u003e1998 Nissan Silvia K [JDM] 2.0L Turbo\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWill an aftermarket flywheel like this work with the stock clutch and pressure plate?\u003c\/h5\u003e\u003cp\u003eIn most cases a lightweight flywheel is designed to work with the stock or a matching aftermarket clutch disc and pressure plate, but the flywheel's bolt pattern, pilot bore, and friction surface height should always be checked against the specific clutch kit being installed.\u003c\/p\u003e\u003ch5\u003eWhat is a \"flywheel step\" and does this flywheel have one?\u003c\/h5\u003e\u003cp\u003eA flywheel step is the raised friction surface machined into the flywheel face that the clutch disc rides against.
