{"product_id":"4140-chromoly-steel-flywheel","title":"4140 Chromoly Steel Flywheel","description":"It is constructed from hardened 4140 Chromoly Steel, featuring a zinc-plated finish for excellent engagement feel, wear resistance, and corrosion protection.\n\nKey benefits of installing this lightweight flywheel include crisper shifts, improved throttle response, and better acceleration, all while offering a lower replacement cost compared to dual-mass units. The flywheel is designed to accommodate specific pressure plates and clutch components, such as the E34 M5 pressure plate, for an OE-type clutch feel. It incorporates a sprung-hub clutch disc to effectively eliminate idle chatter and reduce driveline shock loading.\n\nWeighing in at just 16.5 lbs, this flywheel significantly reduces rotational mass, contributing to quicker engine revs and a more responsive driving experience. Furthermore, it has undergone rigorous testing and certification, meeting SFI Spec 1.1 standards. This SFI certification, indicated by a laser-etched serial number, ensures safe operation for competitive motorsports and long-term street use, providing peace of mind regarding its quality and reliability.\n\nThis flywheel is compatible with a wide range of BMW models, including various 3-Series (E36, E46), 5-Series (E34, E39), and Z3\/Z4 variants from the early 1990s through the mid-2000s.
