FX Racing Aluminum Flywheels are made using the highest quality most modern materials available. The flywheel itself is made from 6061 T6 billet aluminum. It is CNC machined at a constant surface speed for durability and finish. The friction surface is made from high carbon alloy steel. It is incredibly durable allowing the user to use just about any clutch disc material available from organic to and even sintered iron. The friction plate can be machined or replaced as needed. The mass at the center of the flywheel is retained for strength but the mass at the outside is eliminated for optimum performance. -Ultra heavy-duty and weighs only 8.4 lbs -Meets or exceeds SFI 1.1 specification -Course ground surface to maintain coefficient of friction -Stepped pin to maintain plate balance and placement -Tig-welded safety tab to eliminate ring gear separation -Heilicoil bolt holes to insure proper torque value and eliminate thread damage -RETAIL PRICE: $329 Vehicle Application Fits 1997 - 1999 Acura 2.2CL; 2.3CL (2.2L 2.3L 4cyl SOHC engine) Fits 1990 - 2002 Honda Accord (2.2L 2.3L 4cyl SOHC engine) Fits 1992 - 2001 Honda Prelude (2.2L 2.3L 4cyl SOHC DOHC engine)
