Clutch Masters 2-Piece Billet Aluminum Flywheels are made from the highest quality 6061-T6 or better grade aluminum. This material is chosen for its properties that are much more suitable for the environment than the one-piece chromoly units, with regards to heat dissipation and serviceability. The replaceable friction surface used is incredibly tough high carbon steel. This allows mating with any type of clutch friction material without worry. The starter ring gears are made of high carbon heat-treated steel for long lasting durability. The unit is buttoned together with military grade fasteners to make the premier flywheel in the industry. *Features* * Reduced mass equals increased acceleration. * A lightweight flywheel works particularly well with turbo-charged engines because it reduces typical turbo lag. * Increased supercharger efficiency due to less parasitic drag on the crank. * Improved mid-range torque in a normally aspirated engine due to not having to overcome the heavy weight of a stock flywheel. * CM uses only 6061-T6 aircraft grade or better billet aluminum in the manufacturer of its flywheels. * CM uses High Carbon steel for the friction surface. (Replaceable) * CM uses an OEM steel ring gear secured by bolts. * CM offers a limited lifetime warranty. * CM Billet Aluminum Flywheels meet SFI Spec 1.1 or 1.2 PartNumber : cmFW-375-SF Description : Lightweight Steel Flywheel Weight : 18lbs 2008-2013 Audi A3 Base L4.1984cc Drivetrain::Flywheels 2014 Volkswagen Beetle GSR L4.1984cc Drivetrain::Flywheels 2013-2014 Volkswagen Beetle R-Line L4.1984cc Drivetrain::Flywheels 2013-2014 Volkswagen Beetle TDI L4.1968cc Drivetrain::Flywheels 2012-2013 Volkswagen Beetle Turbo L4.1984cc Drivetrain::Flywheels 2014 Volkswagen CC Executive L4.1984cc Drivetrain::Flywheels 2012-2013 Volkswagen CC Lux L4.1984cc Drivetrain::Flywheels 2012 Volkswagen CC Lux Limited L4.1984cc Drivetrain::Flywheels 2012 Volkswagen CC Lux Plus L4.1984cc Drivetrain::Flywheels 2009-2011 Volkswagen CC Luxury L4.1984cc Drivetrain::Flywheels 2011-2014 Volkswagen CC R-Line L4.1984cc Drivetrain::Flywheels 2009-2014 Volkswagen CC Sport L4.1984cc Drivetrain::Flywheels 2013 Volkswagen CC Sport Plus L4.1984cc Drivetrain::Flywheels 2009-2011 Volkswagen Eos Komfort L4.1984cc Drivetrain::Flywheels 2009-2011 Volkswagen Eos Lux L4.1984cc Drivetrain::Flywheels 2015-2017 Volkswagen GTI Autobahn L4.1984cc Drivetrain::Flywheels 2008-2013 Volkswagen GTI Base L4.1984cc Drivetrain::Flywheels 2014 Volkswagen GTI Driver's Edition L4.1984cc Drivetrain::Flywheels 2015-2017 Volkswagen GTI S L4.1984cc Drivetrain::Flywheels 2015-2017 Volkswagen GTI SE L4.1984cc Drivetrain::Flywheels 2017 Volkswagen GTI Sport L4.1984cc Drivetrain::Flywheels 2014 Volkswagen GTI Wolfsburg Edition L4.1984cc Drivetrain::Flywheels 2008-2009 Volkswagen Jetta GLI L4.1984cc Drivetrain::Flywheels 2012-2014 Volkswagen Jetta GLI L4.1984cc Drivetrain::Flywheels 2009 Volkswagen Jetta SEL L4.1984cc Drivetrain::Flywheels 2008-2010 Volkswagen Jetta Wolfsburg Edition L4.1984cc Drivetrain::Flywheels 2010 Volkswagen Passat Komfort L4.1984cc Drivetrain::Flywheels 2012-2013 Volkswagen Passat TDI SE L4.1968cc Drivetrain::Flywheels 2012-2013 Volkswagen Passat TDI SEL L4.1968cc Drivetrain::Flywheels
