Streetlite flywheels are considerably lighter than the factory unit while remaining the most durable flywheel in the ACT lineup, with material properly distributed for strength, lower rotating inertia, good heat tolerance, and rigidity. The flywheel is preferred for street or drag racing use and is fully serviceable, meaning it can be resurfaced without buying additional parts.\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\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eProduct Weight: 18.8 lbs\u003c\/li\u003e\n\u003cli\u003eMaterial: Chromoly steel\u003c\/li\u003e\n\u003cli\u003eFriction Surface Diameter: 9.4 in \/ 240mm\u003c\/li\u003e\n\u003cli\u003eRing Gear: 125-tooth\u003c\/li\u003e\n\u003cli\u003eSFI Rating: 1.1\u003c\/li\u003e\n\u003cli\u003eCounterweight: ACT CW03 counterweight included, assures correct external balance for the RX-8's manual-shift engine using the OE front counterweight\u003c\/li\u003e\n\u003cli\u003eResurfacing Limit: Up to 0.040 in (1.02mm) of material removal\u003c\/li\u003e\n\u003cli\u003ePart Number: 600145-03\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2004 Mazda RX-8 Base\u003c\/li\u003e\n\u003cli\u003e2005 Mazda RX-8 Base\u003c\/li\u003e\n\u003cli\u003e2005 Mazda RX-8 Shinka\u003c\/li\u003e\n\u003cli\u003e2006 Mazda RX-8 Base\u003c\/li\u003e\n\u003cli\u003e2007 Mazda RX-8 Base\u003c\/li\u003e\n\u003cli\u003e2008 Mazda RX-8 40th Anniversary Edition\u003c\/li\u003e\n\u003cli\u003e2008 Mazda RX-8 GS\u003c\/li\u003e\n\u003cli\u003e2008 Mazda RX-8 GT\u003c\/li\u003e\n\u003cli\u003e2008 Mazda RX-8 Grand Touring\u003c\/li\u003e\n\u003cli\u003e2008 Mazda RX-8 Sport\u003c\/li\u003e\n\u003cli\u003e2008 Mazda RX-8 Touring\u003c\/li\u003e\n\u003cli\u003e2009 Mazda RX-8 GS\u003c\/li\u003e\n\u003cli\u003e2009 Mazda RX-8 GT\u003c\/li\u003e\n\u003cli\u003e2009 Mazda RX-8 Grand Touring\u003c\/li\u003e\n\u003cli\u003e2009 Mazda RX-8 R3\u003c\/li\u003e\n\u003cli\u003e2009 Mazda RX-8 Sport\u003c\/li\u003e\n\u003cli\u003e2009 Mazda RX-8 Touring\u003c\/li\u003e\n\u003cli\u003e2010 Mazda RX-8 GT\u003c\/li\u003e\n\u003cli\u003e2010 Mazda RX-8 Grand Touring\u003c\/li\u003e\n\u003cli\u003e2010 Mazda RX-8 R3\u003c\/li\u003e\n\u003cli\u003e2010 Mazda RX-8 Sport\u003c\/li\u003e\n\u003cli\u003e2011 Mazda RX-8 GT\u003c\/li\u003e\n\u003cli\u003e2011 Mazda RX-8 Grand Touring\u003c\/li\u003e\n\u003cli\u003e2011 Mazda RX-8 R3\u003c\/li\u003e\n\u003cli\u003e2011 Mazda RX-8 Sport\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis product can expose you to chemicals including carbon black, glass wool fibers, and silica (in clutch discs), chromium and nickel, which are known to the State of California to cause cancer or birth defects or other reproductive harm.
