Exedy Lightweight Flywheel

A lightweight flywheel is a great upgrade for those of you who want faster revs and better engine response. Less weight means less rotational mass for the engine to turn. The benefits also include an increase in both horsepower and torque although depending on what clutch you choose to install, there may be a slight increase in clutch chatter.

This is a great upgrade that you can perform if you are changing your clutch, or if you are in the middle of a build on your race car, rally car, or daily-driver.
