All SPEC flywheels carry SFI certification.\u003c\/p\u003e\n\u003cp\u003eThe flywheel contributes to power transfer in three ways: it provides a consistent, friction-enhancing surface for the clutch disc; its weight sets the rotating inertia, which controls the ratio of power to acceleration and can make a car quicker or slower depending on gearing, tire, vehicle weight and where in the powerband the output arrives; and it must run true at rpm, with no dimensional runout to produce vibration. SPEC builds flywheels in high-carbon billet steel and aircraft-quality billet aluminum to cover light and medium-weight options, and can advise on the moment of inertia best suited to a given car. SPEC billet flywheels are developed for specific driving environments and are not a one-fits-all lightweight flywheel — consult a SPEC representative for a recommendation.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: single mass billet flywheel\u003c\/li\u003e\n\u003cli\u003eMaterial: aircraft-quality billet aluminum\u003c\/li\u003e\n\u003cli\u003eCrank bolt pattern: 6-bolt (2\/2009 production onward)\u003c\/li\u003e\n\u003cli\u003eCNC machined to a .001 in. tolerance (industry standard is .010 in.) for a flat clutch bedding surface and true balance at rpm\u003c\/li\u003e\n\u003cli\u003eSFI certified\u003c\/li\u003e\n\u003cli\u003eBillet construction — SPEC flywheels are built in high-carbon billet steel and aircraft-quality billet aluminum to suit specific inertia requirements\u003c\/li\u003e\n\u003cli\u003eRebuildable, with a replaceable steel friction plate formulated for clutch bedding and holding power (aluminum and most steel units)\u003c\/li\u003e\n\u003cli\u003eDeveloped for specific driving environments — not a one-size-fits-all lightweight flywheel\u003c\/li\u003e\n\u003cli\u003eClutch compatibility: works with the stock clutch or any stock-design aftermarket self-ratcheting (SAC) pressure plate. \u003cstrong\u003eIt is not an actual dual mass flywheel.\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNot for use with SPEC clutch kits whose part number ends in “-2”.\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eFlywheel weight: 15 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x SPEC billet single mass flywheel\u003c\/li\u003e\n\u003cli\u003ePressure-plate-to-flywheel bolts\u003c\/li\u003e\n\u003cli\u003eComplete kit as supplied by SPEC; see the installation instructions for the full bill of materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone required.\u003c\/strong\u003e This flywheel runs with the stock clutch or a stock-design self-ratcheting (SAC) aftermarket clutch.
