Fidanza Aluminum Flywheels

The best Fidanza part depends on the job: a lightweight aluminum flywheel is the pick for faster rev response when the clutch is already coming out, a short throw shifter sharpens gear changes, and the red cam gear covers Lexus IS cam timing. Fitments here span Honda, Nissan, Subaru, Toyota, and Mitsubishi cars from the 1980-1982 Corolla to the 2017-and-up Civic Type R, so check your year and model first.

A flywheel stores rotational energy between power strokes, and a lighter aluminum wheel changes the response: revs climb and fall faster, which suits fast downshifts and track driving, while very light wheels can make smooth launches take more care. Because the transmission has to come out to reach it, a flywheel swap is normally paired with a clutch job, so browse the wider Clutch range when planning one.

Fidanza is the only brand here, and lightweight aluminum flywheels are its core line, including versions with a replaceable friction plate so the wear surface can be renewed instead of replacing the whole wheel. Coverage is broad: the 2002-2008 Civic Si and 2002-2006 RSX, the 2007-2008 350Z, 2009-and-up 370Z, 2007 G35 Sedan, and 2008-and-up G37, 1990s Civic, Del Sol, and CR-V applications, the 2017-and-up Civic and Type R FK8, the 2006-2012 IS250, the 2005-2010 Scion tC, and the 1980-1982 Corolla 3TC 5-speed.

Fidanza's range goes beyond flywheels. A red cam gear for the 2000-2005 Lexus IS 3.0L covers adjustable cam timing, replacement friction kits are listed for the 1993-1998 Supra and 2008-2015 Evo X GSR, and short throw shifters cover the 2001-2006 WRX, Subaru 5-speed cars from 1996-2006, and the 2003-2009 Corolla. Good starting points are the lightweight aluminum flywheel for the 2002-2008 Civic Si and 2002-2006 RSX, the aluminum flywheel for the 350Z, 370Z, G35, and G37, and the aluminum flywheel for the Civic Type R FK8.

Since a flywheel is usually fitted with a new clutch, the clutch brands carried here are the natural cross-shop. ACT is known for kits matched to street and track torque levels, Competition Clutch covers staged kits from daily use to competition, and Exedy is chosen by many owners for an OEM-style feel with more capacity. Our guide to enhancing your Subaru's clutch for performance covers how clutch and flywheel work as a pair.

Should I replace the flywheel when I replace the clutch?

It is the sensible time, because the transmission is already out and labor is the biggest cost. At minimum the stock wheel needs inspection; a lightweight wheel is the upgrade path here.

What does a replaceable friction plate do?

It lets you renew the surface the clutch disc grips without replacing the whole flywheel. Fidanza lists friction-plate versions for the Del Sol, Civic Si, and CR-V, plus replacement kits for the Supra.

Will a lightweight flywheel suit a daily driver?

Many owners run one daily, but revs fall faster between shifts and launches can need more throttle. If you mostly commute, weigh that against the response gains, and check your exact application.

Are the short throw shifters a big install?

They replace the factory shifter for the listed application, such as the 2001-2006 WRX or 2003-2009 Corolla, and are a common home install. Confirm your transmission and year first, since fitments here are 5-speed specific.
