XACT Prolite flywheels are ACT's lightest and lowest-inertia flywheel offering, engineered for the sharpest throttle response and quickest acceleration. Materials are properly distributed for maximum strength, lower rotating inertia, good heat tolerance, and rigidity. Prolite flywheels are best suited to road racing or rally racing applications and come with somewhat reduced low-speed drivability compared to a heavier stock flywheel. The flywheel is fully serviceable and can be resurfaced without purchasing 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\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConstruction: Chrome-moly\u003c\/li\u003e\n\u003cli\u003eWeight Class: ACT's lightest, lowest-inertia flywheel offering\u003c\/li\u003e\n\u003cli\u003eCounterweight: Required ACT counterweight included for RX-8 rotary applications\u003c\/li\u003e\n\u003cli\u003eServiceable: Yes, resurfaceable with no additional parts required\u003c\/li\u003e\n\u003cli\u003eRecommended Use: Road racing or rally racing (reduced everyday drivability versus a stock-weight flywheel)\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 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 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 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 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\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eDoes this flywheel kit include the counterweight needed for RX-8 installation?\u003c\/h5\u003e\u003cp\u003eYes.
