2012-2015 Honda Civic Si (OEM ECU) ClutchMasters Lightweight Steel Flywheel

Clutch Masters Steel Flywheel

Typical benefits of a lightweight flywheel for various engine types:
-Reduced mass equals increased acceleration.
-A lightweight flywheel works particularly well with turbo-charged engines because it reduces typical turbo lag.
-Increased supercharger efficiency due to less parasitic drag on the crank.
-Improved mid-range torque in a normally aspirated engine due to not having to overcome the heavy weight of a stock flywheel.
-CM uses High Carbon steel for the friction surface. (Replaceable)
-CM uses an OEM steel ring gear secured by bolts.
-CM offers a limited lifetime warranty.
-CM Steel Flywheels meet SFI Spec 1.1 or 1.2
