Product Description

The Clutch Masters FW-150-SF lightweight steel flywheel is engineered for 2017-2021 Honda Civic models powered by the 1.5 L turbo engine, including Si variants. Weighing just 26 lb, this single-disc replacement cuts significant rotating mass compared to the stock dual-mass unit, resulting in sharper throttle response and quicker turbo spool without sacrificing street comfort.

Machined from durable 1045 steel, finished with rust-resistant black oxide, and zero-balanced to OE specifications, it delivers smooth, dependable performance for both daily driving and light racing. SFI 1.2 certification ensures racing safety compliance, while the retained heat-shield simplifies installation and service. Built and balanced in the USA, this flywheel pairs perfectly with Clutch Masters FX-series or OEM clutches.
