Flywheels
Flywheels: the piece between your engine and your clutch
The flywheel bolts to the back of the crankshaft and gives the clutch a friction surface to clamp against. It also stores rotational inertia, which is what smooths out idle and helps you launch from a stop without stalling. When you fit a new clutch, you resurface or replace the flywheel at the same time, because a worn, heat-checked or hot-spotted face will chew through a fresh disc. People also swap to a lighter flywheel to let the engine rev up and down faster, which sharpens throttle response at the cost of some low-speed drivability. This is drivetrain work, and it is the right time to do it once.
What ThreePiece stocks
There are 153 flywheels here, and 136 of them carry vehicle fitment data. Current prices run from $88 to $1,716 for what is in stock right now - that range moves as inventory changes, so it is not a fixed quote. Seven brands are represented: Fidanza leads with 63 listings, followed by Competition Clutch (33), Clutch Masters (18), Exedy (15), SPEC (12), McLeod Racing (8) and XCLUTCH (4).
Coverage spans model years 1955 through 2024, with common applications including the Mazda Miata, Ford Mustang, Acura Integra, Mitsubishi Eclipse, Toyota Supra, Honda Civic, Nissan 240SX and Subaru WRX STi. Examples in stock: the Fidanza Lexus IS250 aluminum flywheel and the Fidanza Dodge Viper / Ram SRT-10 aluminum flywheel at the mid-range, up to the McLeod 2024 Mustang GT RXT HD aluminum flywheel and the Clutch Masters Audi RS3 DCT steel flywheel near the top.
How to choose
The first split is material. Aluminum flywheels, like the McLeod Challenger 5.7L/6.4L aluminum flywheel, are lighter and free up the engine to rev quickly - good for a responsive build, less forgiving at a crawl. Steel holds more inertia for smoother street manners and takes abuse well. The second split is single-piece versus dual-mass and DCT applications - transmissions like the BMW F80 M2/M3 7-speed DCT flywheel require a part built specifically for that gearbox and clutch pack. Match spline count, bolt pattern and starter tooth count to your exact engine and transmission; the product names here list those details.
What else you need
A flywheel is half the job. Order it alongside clutch components - the disc, pressure plate and release bearing - so the friction surfaces are matched and fresh. Clutch rebuild kits bundle much of that together. While the transmission is out, it is also the moment to look at clutch levers, shift components and axles if any are worn.
