Clutch Masters 2016 Ford Focus RS 2.3L Lightweight Steel Flywheel
Pulling the gearbox on a Ford Focus RS for a clutch and wondering what to bolt to the crank this time? Clutch Masters FW-230-SF is a lightweight steel flywheel for the 2.3L EcoBoost RS with the 6-speed manual and all-wheel drive, listed here for the 2016 model year. It is the choice for an owner who wants quicker throttle response than the factory flywheel gives, but who still drives the car on the street and does not want the extra noise and fussiness of an aluminum flywheel.
The flywheel is the friction face the clutch disc clamps against, and on the RS everything downstream of it is busy: the 6-speed sends torque to the front wheels and to the power take-off unit that feeds the rear drive unit. Every gear change and every launch passes through this one surface, so it has to stay flat, cool and balanced.
FW-230-SF is a one-piece steel flywheel. Clutch Masters lists a 17.0 lb shipping weight for it, and the box adds to that figure, so the part itself is lighter. Less rotating mass lets the 2.3L turbo rev up and drop rpm faster between shifts, which helps on a back road or a track day. Steel also holds up to heat better than aluminum and gives the clutch a solid face to grip, which is why it is the usual pick for a car that sees daily miles.
One thing changes with the clutch you pair it with. Clutch Masters builds its RS kits in two versions: an R suffix uses a rigid disc meant for the factory flywheel, and a D suffix uses a dampened disc meant for an aftermarket single-mass flywheel like this one. A dampened disc gives back some of the cushioning a single-mass flywheel removes.
With the gearbox out, look across the friction face for heat checking, hard spots and a dished or worn surface, and check the bolt holes and crank mounting face for fretting. A face that is only lightly glazed can sometimes be machined; our guide on resurfacing versus replacing a flywheel walks through the call. If the complaint is slip, make sure it really is the clutch first. Our slipping diagnosis guide shows how to compare engine speed against road speed, and flare versus slip helps separate a shift flare from a worn clutch.
Our listing is for the 2016 Ford Focus RS 2.3L turbo AWD 6-speed. Clutch Masters catalogs FW-230-SF for the 2016-2018 Focus RS 2.3L turbo AWD 6-speed, so later RS cars share the same application, but send us your year and VIN and we will confirm it before it ships. It is not for the front-drive Focus ST, the 2.0L Focus or any automatic Focus. For more weight savings, the FW-230-AL aluminum flywheel covers the same car. More RS clutch parts are in our clutch and rebuild kits section.

A Clutch Masters RS kit with the dampened D-suffix disc. Clutch Masters designs its rigid R-suffix discs for the factory flywheel and its dampened discs for an aftermarket single-mass flywheel.
Steel. It is heavier than the FW-230-AL aluminum version but handles heat better and is easier to drive and quieter around town. Aluminum suits a car that spends a lot of time on track.
Expect some added gear rattle at idle compared with the factory flywheel, and a car that drops rpm faster between shifts. A dampened clutch disc helps keep that in check.
Yes, use new bolts and torque them in stages to the factory spec. A Flywheel Friction Lock shim between crank and flywheel is a worthwhile add for a car that sees launches.
