The Zero Sports WRC Crank Pulley is a great upgrade from the stock and extremely heavy crank pulley. The old stock piece weighs in at 2.5 KG while this Zero Sports WRC Crank Pulley weighs in at ONLY .75 KG. This is due to the light weight aluminum material used to produce it. After installed, the driver will feel more response in the accelerator from the decrease in inertial weight.
