The stock flywheel was designed with extra weight to make daily stop and go driving as easy as possible. The disadvantage of this weight is that your engine has to use more power to accelerate the flywheel which causes slower revs and an elastic feeling when engaging the clutch. If you’re building your car for higher performance, a performance lightweight flywheel will allow the engine to accelerate quicker with more power getting transferred to the asphalt. For comparison purposes, the stock flywheel weighs over 20lbs, the Chromoly StreetLite flywheel weighs 13.8lbs and the Bönez Ultra light units weighs 9.6lbs. The Exedy system is the featherweight of the bunch, but is not comparable since it has a totally different clutch geometry. The prices for these flywheels include the required counterweight and hardware.
