Clutch Masters 01-03 BMW 325 2.5L E46 5-Speed FX400 6-Puck Clutch Kit

Clutch Masters 03049-HDC6-D is the FX400 six-puck ceramic clutch kit for the 2001-2003 BMW 325 E46 with the 2.5L six and five-speed manual. It is aimed at the E46 that has gone well past stock: a supercharger, a turbo kit, a stroker build or a dedicated drift or track car where the factory clutch and dual-mass flywheel simply cannot keep up. If you want a smooth commuter clutch for a stock 325i, this is not it; this is the kit for maximum holding power.

What the FX400 clutch does in an E46 325

The 325i five-speed uses the Getrag 250G gearbox behind the M54 six, with a dual-mass flywheel and an organic disc from the factory. The FX400 replaces that with Clutch Masters' Power Plus I high-leverage heavy-duty pressure plate and a sprung ceramic button disc with six pads and no marcel cushion. Clutch Masters rates it at a 170 percent increase in holding capacity and describes it as an extreme-duty street, road race and drag setup. The sprung hub keeps some damping for street use, but the six-puck design engages quickly and Clutch Masters warns it may chatter slightly in first and reverse. The -D suffix means a dampened disc built to run with an aftermarket single-mass flywheel, not the factory dual-mass unit.

Symptoms that call for this clutch

• Slip in third and fourth at full throttle after forced induction or a big power upgrade
• Clutch smoking or fading during track days, drifting or repeated launches
• Engagement point that keeps climbing as the original disc wears thin
• Rattle or clunk at idle that goes away when the pedal is pressed, a common sign the dual-mass flywheel is worn
• Shudder pulling away or a pedal that feels soft or sticks

How to confirm it before you buy

A slipping clutch shows rpm climbing faster than road speed on a hard pull in a high gear. On an E46, also check the clutch slave and the delay valve in the hydraulic line, and look for oil from the rear main seal or transmission input seal. Our slipping diagnosis guide covers the steps, and the manual repair cost guide helps you budget the job.

Fitment

Our listing covers the BMW 325 2001-2003 E46 with the 5-speed. Clutch Masters also lists 03049-HDC6-D for the 2000 323 E46, 1999-2000 328 E46, 2001-2003 330 E46 5-speed, 1999-2000 528 and 2001-2003 525 and 530 E39, 2001-2005 X5 3.0L, 1999-2002 Z3 2.5L and 2001-2002 Z3 3.0L, and the 2003 Z4 2.5L five-speed. Six-speed cars and the M3 use different kits. Confirm your gearbox before ordering, or send us the year and VIN and we will check. Other BMW clutch options are in the rebuild kits and clutch section.

Install notes

• The kit includes the pressure plate, disc, release bearing, pilot bearing where applicable and an alignment tool. A flywheel is not included and this disc needs a single-mass flywheel such as the SPEC steel flywheel SB64S.
• BMW self-adjusting pressure plates need care on removal; the BMW SAC alignment tool kit makes centering the disc easier.
• Use new flywheel bolts, tighten the pressure plate bolts gradually in a crossing pattern to factory torque, and inspect the plastic clutch fork pivot while the gearbox is out.
• Bleed the clutch with the brake fluid specified on the reservoir cap until the pedal is firm.
• Follow the Clutch Masters break-in: at least 500 miles of normal driving before hard launches.

Does 03049-HDC6-D work with the factory dual-mass flywheel?

No. The -D version uses a dampened disc designed for an aftermarket single-mass flywheel. Plan on a single-mass flywheel as part of the job.

Will it fit a 2004-2005 325i?

Clutch Masters lists the 325 for 2001-2003 with the 5-speed. For a later car, send us the VIN so we can confirm the gearbox and clutch before it ships.

Is the 6-puck FX400 good for daily driving?

It is built for heavily modified and track cars. It engages quickly and may chatter in first and reverse. A stock or lightly modified 325i will be happier with a street disc.

What comes in the kit?

Pressure plate, sprung 6-puck ceramic disc, release bearing, pilot bearing where applicable, an alignment tool and an instruction card. No flywheel.

How long is the break-in?

Clutch Masters calls for at least 500 miles of normal driving before launches or full-throttle shifts.
