Spec 12-18 Ford Focus ST D-Trim Twin Disc Clutch Kit

This SPEC D-Trim Twin Disc Clutch Kit includes the clutch assembly, a lightweight billet steel flywheel, and a pilot bearing. It's built for the 2012-2018 Ford Focus ST, designed to handle significantly more power than the stock clutch. Twin disc setups like this one are a popular choice for high-performance applications because they spread the clamping force over a larger surface area, which helps manage the heat generated during aggressive driving and allows for higher torque capacity.

The D-Trim designation means this clutch uses a sprung center hub design, which helps absorb some of the driveline shock and can make engagement a bit smoother compared to some other performance clutch designs. The lightweight billet steel flywheel is crucial for quick engine response, allowing the engine to rev up and down more freely. This setup is engineered to be a direct replacement for your factory clutch, though it's important to note that a twin-disc clutch generally requires a firmer pedal feel and may have a more abrupt engagement than a stock clutch. Because it's a twin-disc setup, you'll have two friction surfaces working together, which greatly increases the clutch's ability to hold power and dissipate heat, making it a solid choice for track days or heavily modified vehicles.

When installing a twin-disc clutch, it's always a good idea to have a new rear main seal and transmission fluid on hand. Proper break-in is also essential for the longevity of the clutch discs. Refer to the manufacturer's installation instructions for the specific break-in procedure, which typically involves a series of gentle drives and moderate acceleration cycles to properly seat the friction materials.
