ACT 15-17 Volkswagen Golf R HD/Race Sprung 6 Pad Clutch Kit

Once a Mk7 Golf R is running a big-turbo kit, an ethanol blend or an aggressive Stage 2+ tune on a road course or drag strip, an organic street disc starts to fade from heat. ACT VW9-HDG6 is the race-oriented answer for the 2015-2017 Golf R six-speed manual: a Heavy Duty pressure plate clamping a 6-pad sprung ceramic disc, rated by ACT at 640 ft-lb at the crank, 102 percent more than the factory clutch. It is built for cars that see real heat, not for the owner who wants the smoothest commute.

What the HD race 6-pad clutch does in a Golf R

Torque capacity in this kit comes from two places. The ACT Heavy Duty pressure plate (VW015) uses a heat-treated diaphragm that raises clamp load and resists deflection at high rpm. The disc (6240527) swaps a full organic face for six ceramic friction pads, which tolerate far more heat before they glaze or fade. With less pad area and a harder material, engagement is sharp and the car bites quickly, a trade ACT makes for faster shifts. The disc keeps a spring center, so torsional shocks are still damped on the way into the gearbox and the all-wheel-drive driveline instead of hitting them solid.

The kit also replaces the factory dual-mass flywheel with ACT's XACT Streetlite flywheel (601050), which ACT says must be used with this clutch. Also in the box: an RB011 release bearing, an AT126 alignment tool, flywheel bolts (M10-1.0 x 22 mm) and pressure plate bolts (M8-1.25 x 20 mm). Disc diameter is 240 mm (9.4 inch), the input spline is 0.9375 inch, and the kit ships at about 31.8 lb.

Symptoms that call for a race clutch

• Slip that only shows up late in a track session or after several back-to-back launches, when an organic disc is hot
• Engagement point moving or going vague after heavy use, then coming back once the car cools
• Burnt friction smell in the paddock or the pits
• Glazed or heat-checked friction surfaces found when a previous street clutch came out
• Rev flare at full boost in fourth through sixth gear on a tune that exceeds what a street kit is rated for

How to confirm before you buy

Separate heat fade from a worn disc. A worn disc slips cold and warm; heat fade usually appears only after repeated hard pulls. Log a full-throttle pull in fourth gear and compare rpm to wheel speed. Check for a pedal that does not return fully or sinks, since a hydraulic fault can mimic slip, and look for oil on the bellhousing. Our slipping diagnosis guide walks through the checks, and the manual versus automatic repair cost breakdown helps you plan the labor bill. If you drive the car daily and only see slip on full boost, ACT's organic VW9-HDSS street kit or the VW9-XTSS Xtreme street kit may suit you better.

Fitment

This listing is cataloged for the 2015-2017 Volkswagen Golf R with the 2.0 liter turbo four and six-speed manual. ACT's own application chart for VW9-HDG6 is broader: it lists the 2015-2019 Golf R and the 2015-2021 GTI (Autobahn, Base, S, SE, Sport, Performance and Rabbit Edition trims). It does not apply to DSG automatic cars. If your car has had a transmission swap, or you want us to confirm against the build, send the year and VIN before ordering. More performance clutch kits are in our rebuild kits department.

Install notes

• Install the included Streetlite flywheel with the supplied M10 bolts. ACT states this kit must be used with the ACT flywheel; the factory dual-mass unit does not go back in.
• Center the disc with the AT126 tool and tighten the M8 pressure plate bolts gradually in a star pattern to the factory torque spec.
• Fit the new RB011 release bearing and inspect the slave cylinder and clutch line while the gearbox is out.
• Bleed the clutch hydraulics completely with the brake fluid the car specifies and confirm full release before the first drive.
• Race discs bed in differently from organic discs. ACT says its race discs usually need only a few hard slips to lap in the surfaces, but do not overheat the clutch while bedding it.
• Expect pedal effort 15 to 40 percent above stock with ACT's Heavy Duty plate, and more chatter on takeoff than a street disc.

Is this clutch good for daily driving a Golf R?

It can be driven on the street, but ACT describes engagement as aggressive and recommends it for high horsepower street or race use. If the car is mostly a commuter, an organic street disc such as VW9-HDSS will be smoother.

Does it fit a Mk7 GTI as well?

ACT's application chart lists VW9-HDG6 for the 2015-2021 GTI with the six-speed manual as well as the 2015-2019 Golf R. Our listing is cataloged for the 2015-2017 Golf R, so send the year and VIN if you want us to confirm your car.

Can I reuse my factory dual-mass flywheel?

No. ACT states this kit must use the ACT XACT Streetlite flywheel, which is included along with the flywheel bolts.

What comes in the box?

The Streetlite flywheel (601050), Heavy Duty pressure plate (VW015), 6-pad sprung race disc (6240527), RB011 release bearing, AT126 alignment tool, and both flywheel and pressure plate bolts.

How do I break in a 6-pad ceramic disc?

ACT says its race discs usually need only a few hard slips to lap in the friction surfaces. Avoid long slipping or overheating the clutch during that first period.
