The Clutch Masters FW-550-SF is a lightweight steel flywheel for the 4.4L V8 BMW 550i and 550i GT. It is designed in CAD and CNC machined in house in the USA from a 1045 steel billet core, then zero balanced so it is evenly weighted and spins true. A black oxide coating adds rust prevention, and each flywheel is inspected for imperfections and tolerances before it ships. Lower rotating mass lets the engine rev more quickly and helps reduce turbo lag, and the flywheel is SFI 1.2 certified for motorsport use. It is ready to pair with Clutch Masters FX100 through FX500 single disc clutch kits.
