ACT 16-18 Ford Focus RS / ST XT/Perf Street Sprung Clutch Kit
A tuned Focus RS or Focus ST puts a lot more torque through the clutch than Ford designed it for, and the stock disc is usually the first part to complain. If your car flares at full boost, smells hot after a few pulls or launches, or the engagement point has moved up the pedal, ACT FF5-XTSS is built for that problem. It combines ACT's Xtreme pressure plate with an organic Performance Street disc, rated at 582 ft-lb at the crank, and includes a lightweight flywheel, so a tuned 2.3 or 2.0 EcoBoost car keeps a street-friendly take-off.
Holding power comes mostly from the F024X Xtreme pressure plate. ACT's heat-treated diaphragm raises clamp load and resists deflection at high rpm, which is where an over-boosted stock plate starts to let the disc slip. The 3001012 Performance Street disc keeps a full organic face with high copper content and a steel-backed lining, plus reduced marcel for quicker shifts. The result is the engagement character of an organic street disc with clamp load well above the Heavy Duty version. ACT lists the feel as moderate to heavy pedal effort with smooth engagement.
In the box: the XACT Streetlite flywheel (601020), the F024X pressure plate, the 3001012 disc, an RB009 release bearing and an AT130 alignment tool. The disc is 240 mm (9.4 inch), the input spline is 1 inch, and the kit ships at about 29.6 lb.
Confirm it is the clutch and not the hydraulics. A pedal that sticks or returns slowly, a low or dark reservoir, or a soft feel can keep the clutch partly released and look exactly like slip. Check the bellhousing seam for oil contamination. Then make a fourth-gear full-throttle pull from low rpm and watch whether engine speed rises faster than road speed. Our slipping diagnosis guide walks through those checks, and the repair cost breakdown covers what clutch labor runs on a car where the gearbox has to come out.
This listing is cataloged for the 2016-2018 Ford Focus RS (2.3 liter EcoBoost) and Focus ST (2.0 liter EcoBoost) with the six-speed manual. ACT's application chart also lists the 2013-2015 Focus ST, so earlier ST owners are covered by the same part number. It does not apply to non-ST Focus models or to cars with an automatic or dual-clutch gearbox. If you are not sure, send the year and VIN and we will confirm before you order. More kits are in our rebuild kits department.
If you want the lightest pedal, the FF5-HDSS Heavy Duty street kit is rated at 500 ft-lb. FF5-XTSS sits in the middle with more clamp load and the same organic feel. For track use or large turbo builds, the ceramic 6-pad race kits, FF5-HDG6 and FF5-XTG6, hold 640 and 745 ft-lb but engage much more abruptly.
