ACT's FF3-HDSS clutch kit for the Focus ST is a full replacement of your entire clutch system from throwout/release bearing to the flywheel. It includes the heavy duty pressure plate which increases the clamping load on the clutch disc and will hold higher levels of torque than the factory pressure plate. The disc is a sprung style to help reduce NVH (noise, vibration, harshness) since it is a using a new single mass flyhweel, instead of the original dual mass flyhweel. It still retains a full face of clutch friction material for more consistent feel and engagement. You will experience a little more noise and vibration with this kit over the their more basic kit that uses the factory flywheel. However, the engine will be quicker to spin up and react to clutch inputs due to the lighter nature of the entire setup.
This clutch is rated to 445 ft. lbs. or torque at the flywheel. This would be a great clutch for any stock turbo Focus ST with or without supporting power modifications.
All individual components are available separately for any future replacement needs.
This clutch and flywheel package is perfect. 2017 ST with all the MOUNTUNE bolt-ons plus their tune done 4 months into the cars life as my daily driver, covering about 600 miles per week (that's not a typo, 600). These mods made this a whole different car. Quickly became too much for the stock clutch. From my research for options that are out there, Edge Autosport, and this clutch and flywheel package were EXACTLY what I was looking for. I'm 500 miles in so she's broke in, there's almost no noise, a small chatter at idle with the car in neutral and the clutch disengaged. You can only hear that noise with the air and radio off, turn either of those on and it drowns that noise out it's so feint so it's really no bother. This thing puts ALL the power to the wheels, it grabs like no other, and it does it without that heavy pedal that makes your left leg get bigger than your right leg. It's only slightly heavier than a stock clutch pedal, you'll get used to it quick and forget what stock felt like. What really sold me, besides ACT's great reputation and Edge's honest answers and great service, was that I wanted a flywheel that would rev faster but still be serviceable for my daily driver. This single mass flywheel is perfect. Free revs feel twice as quick without the race car noise an aluminum unit would give, showing up to a customers home in race cars tend to scare them so this is perfect. Special thanks to JP and his crew, I have a feeling we're going to have a long relationship!
