Aftermarket lightweight flywheels and heavy duty clutches are not currently one of the more popular topics of discussion between #FocusST owners due to the fact that these cars are new and most have low mileage. Soon enough though it will become a much more regular subject as the need to replace the factory parts on your dime will become a reality. Rest assured that when that time comes we have ...you covered. CFM Performance has worked closely with our friends at Clutch Masters to help develop clutches in several different stages to suit different needs. Also, we are currently the only company to offer single mass billet flywheels in both aluminum and steel. There are several reasons and advantages to replacing the factory parts with aftermarket pieces but we will get into more details about those later. There is one that we cannot wait to share though. When replacing your factory clutch and flywheel with our lighter components you will notice an immediate increase in power due to the reduction of parasitic losses created by the much higher weight of the factory parts. We did some dyno testing on our project car and are very excited to share the results. Check them out at our online store.
