ACT 04-05 BMW 330i (E46) 3.0L HD/Race Sprung 6 Pad Clutch Kit (Must use w/ACT Flywheel)
ACT BM16-HDG6 is a race-oriented clutch for the late E46 BMW 330i, 330Ci and 330xi with the 3.0L M54 six and the six-speed manual. It is the kit owners reach for when a supercharger, turbo or track use has outgrown both the factory clutch and the softer street upgrades: the car flares on hard upshifts, the revs climb without road speed in the upper gears, or the original dual-mass setup is worn out and you want a solid single-mass package instead.
ACT pairs its Heavy Duty pressure plate (B015) with a 6-pad, spring-centered ceramic race disc (6240533). ACT rates the combination at 596 ft-lb measured at the crank, which it lists as 94 percent over the factory clutch. The disc is 9.4 in (240 mm) on a 1.125 in input shaft. Because there are six small ceramic pads instead of a full organic face, the disc carries far more heat and torque, but ACT is clear that engagement is harsher; the sprung hub is there to damp driveline shock, not to make it feel stock. Pedal effort is rated light to moderate, and ACT says its Heavy Duty plates typically add 15 to 40 percent pedal effort.
The important detail: ACT states this kit must be used with an ACT flywheel, which is not included. The matching part is the ACT 601160 Streetlite flywheel, a single-mass conversion with 113 teeth and a 240 mm friction face. ACT notes gear rattle is expected with that flywheel and includes the M12-1.5 x 25 mm flywheel bolts. The clutch kit itself contains the B015 plate, 6240533 disc, RB1401 release bearing, AT103 alignment tool and the M8-1.25 x 20 mm pressure plate bolts.
Separate clutch faults from hydraulic ones first. A soft pedal or grinding into gear on an E46 usually means air in the system or a leaking slave cylinder, and a new clutch will not cure it. To test for slip, hold a high gear at low rpm and go to full throttle; if the tach jumps ahead of road speed, the clutch is not holding. Our slipping diagnosis guide covers the test, and shift flare vs. slip helps if you are not sure what you are feeling. Check the bellhousing for oil too; a rear main or transmission input seal leak will ruin a new disc.
Our listing is for the 2004-2005 BMW 330i (E46) 3.0L. ACT's application chart for BM16-HDG6 covers the 2004-2006 330i, 330Ci and 330xi, the 2004-2005 530i (E60) and the 2004-2006 X3 2.5i/3.0i (E83), all with the M54 six and a six-speed manual. Earlier E46 cars with the five-speed are not on the chart, and neither is the E46 M3, which has its own kits. If your car is a 2004-2005 330i, confirm it has the six-speed, or send us the year and VIN and we will check before it ships. Other clutch packages are in our rebuild kits section.
With the driveshaft already off, many owners replace the E46 flex disc and center support bearing at the same time. If you want a smoother street feel with more holding power, compare the XClutch twin-disc organic kit.

No. ACT says the kit must be used with an ACT flywheel, which is sold separately. The matching part is the 601160 Streetlite single-mass flywheel, which includes its M12-1.5 x 25 mm bolts.
ACT lists BM16-HDG6 only for 2004-2006 330i/330Ci/330xi with the six-speed, plus the 2004-05 530i and 2004-06 X3 six-speed. Five-speed E46 cars are not on its chart, so send us your year and VIN before ordering.
ACT rates BM16-HDG6 at 596 ft-lb at the crank, 94 percent over the factory clutch.
It can be driven on the street, but the 6-pad ceramic disc engages much more abruptly than stock, and the single-mass flywheel brings gear rattle. ACT recommends it for high horsepower street or race use.
The 601160 flywheel is required. While the transmission is out, inspect the pilot bearing, clutch slave cylinder and driveshaft flex disc, which are common E46 wear items.
