Clutch Masters 2016+ Honda Civic 1.5L Turbo Aluminum Flywheel
The Clutch Masters FW-150-AL is a lightweight aluminum single-mass flywheel for the tenth-generation Honda Civic with the 1.5L turbo and six-speed manual in EX and Si trims. Civic owners shopping for it usually have a factory dual-mass flywheel that has started to rattle or shudder, a clutch that slips once the car is tuned, or simply want the 1.5T to rev more freely than it does with the heavy stock unit. It is the flywheel half of a Clutch Masters single-mass conversion, so plan it together with the clutch kit.
The factory flywheel on the manual 1.5T is a dual-mass design: two halves joined by springs that soak up engine pulses before they reach the gearbox. It is smooth, but heavy, and the springs and bearing wear out. FW-150-AL replaces it with a single solid aluminum piece. Clutch Masters CNC machines it in the USA from 6061 aluminum, zero balances it, Type 3 hard anodizes the body and certifies it to SFI 1.2. With far less rotating mass, the turbo four picks up and sheds rpm faster, which cuts the rev hang between shifts. The trade-off is that a sprung clutch disc now handles the vibration damping instead of the flywheel.
Start with the clutch. Warm the car, select fourth around 2,000 rpm and go to full throttle on a safe road; rpm rising faster than speed means slip. Our slipping diagnosis guide walks through it, and our dual-mass flywheel failure guide explains how to recognize a worn factory unit. With the transmission out, a dual-mass flywheel that rocks or turns more than a small amount between its halves is due for replacement.
Clutch Masters lists FW-150-AL for the 2017-2021 Honda Civic 1.5L turbo with the six-speed manual, EX and Si trims. Our listing title says 2016+; Clutch Masters does not list a 2016 application, so 2016 owners should send us the VIN before ordering. It does not fit CVT cars, the 2.0L Civic, the Type R, or the 2022-on Civic, which uses a different flywheel. Pair it with a Clutch Masters sprung kit made for the single-mass conversion, such as the FX100 kit 08150-HD00-D for a stock or lightly modified car or the FX250 sprung kit for a tuned one. The rigid -R kits are meant for the factory dual-mass flywheel. If you would rather keep more mass for daily driving, the steel FW-150-SF fits the same cars.
Swap the flywheel during the clutch job with the transmission out. Clean the crankshaft flange and threads and check the rear main seal for oil; fix any leak now. Use new flywheel bolts with the thread locker and torque from the Clutch Masters instructions, tightening in a cross pattern. Clean the friction face with brake cleaner, center the disc with an alignment tool like the Powerbuilt 8-piece pilot tool set, and tighten the pressure plate evenly. Bleed the hydraulics with the brake fluid named on the reservoir cap and follow the Clutch Masters break-in. Expect more gear rattle at idle and a little more throttle needed on takeoff than with the factory dual-mass flywheel.

Clutch Masters lists 2017-2021 Civic 1.5L turbo manual cars, EX and Si. It does not list a 2016 application, so send us the VIN before ordering for a 2016.
A Clutch Masters sprung kit for the single-mass conversion, such as FX100 08150-HD00-D or the FX250 sprung kit. The rigid -R kits are for the factory dual-mass flywheel.
No. It is listed for the 2017-2021 Civic 1.5L turbo manual only.
Aluminum gives the quickest rev response. The steel FW-150-SF keeps more mass, which makes takeoffs and traffic easier on a daily driver.
Clutch Masters lists a 17 lb shipping weight including the box; it does not publish the bare flywheel weight.
Yes, some gear rattle at idle is normal when replacing a dual-mass flywheel with a single-mass one.
