Clutch Masters FX100 Clutch Kit 05-07 BMW 330i 3.0L

70% More Holding Capacity Than Stock, Built for Street Performance on Your BMW E90 or E46

The Clutch Masters 03CM3-HD00-SK FX100 Clutch Kit delivers a substantial upgrade over the factory clutch system without sacrificing the streetable feel you rely on every day. Engineered specifically for 2005, 2006, and 2007 BMW 330i, 330Ci, and 330xi applications running the N52 and comparable inline-six engines with a 6-speed manual transmission, this kit replaces your entire clutch assembly including the dual-mass flywheel with a proven single-mass steel unit.

What's Included

• FX100 Power Plus I Heavy-Duty Pressure Plate
• Steel-backed organic friction disc
• Throwout bearing (release bearing)
• Pilot bearing
• Clutch alignment tool
• Replacement single-mass steel flywheel

Everything needed for a complete clutch service is in the box. No sourcing additional components separately.

Why the FX100 Series Works for Your BMW

The 03CM3-HD00-SK uses the Power Plus I Heavy-Duty Pressure Plate paired with a steel-backed organic friction disc. This combination gives you 70% more holding capacity compared to the original equipment clutch while keeping pedal effort only slightly above stock. You get a smooth, natural engagement feel that does not punish you in traffic or on long commutes.

The included single-mass steel flywheel replaces the OEM dual-mass unit, which is a common failure point on these BMW platforms. The steel flywheel provides a more direct power delivery feel and eliminates the complexity and cost associated with dual-mass flywheel replacement. Note: The 03CM3-HD00-SK will not function with the OEM flywheel. The Clutch Masters steel flywheel included in this kit must be used.

Ideal Application Range

The FX100 is designed for street-driven vehicles with minor bolt-on modifications. Compatible upgrades include:

• Exhaust system upgrades
• Cold air or short-ram intake systems
• Up to 50 horsepower nitrous oxide systems
• Other non-forced induction external bolt-ons

This kit is not intended for forced induction applications. If your BMW is turbocharged or supercharged, or if you are planning forced induction in the future, the FX300 series or higher is recommended for your build.

Why Clutch Masters

Clutch Masters has been engineering performance clutch systems since 1986. Every kit is designed, manufactured, and tested at their facility in Yorba Linda, California. The FX series product line covers applications from mild street builds all the way through full race configurations, with each tier purpose-engineered rather than simply uprated from a generic platform. The 03CM3-HD00-SK is a vehicle-specific design for these BMW E90 and E46 chassis, not a universal fitment adapted to fit.

Clutch Masters products are covered under the Magnuson-Moss Warranty Act. This federal law protects consumers by ensuring that warranty coverage for aftermarket parts cannot void your vehicle's factory warranty simply for using a qualifying replacement component.

Installation Instructions

Professional installation by a qualified transmission technician is recommended. The following steps outline the general procedure for replacing the clutch assembly on the applicable BMW models.

1. Preparation: Safely raise and support the vehicle. Disconnect the battery negative terminal. Gather all necessary tools including a transmission jack, flywheel holding tool compatible with your BMW, and a torque wrench.
2. Transmission removal: Disconnect the driveshaft at the transmission flange. Disconnect the shift linkage, clutch slave cylinder hydraulic line, and all electrical connectors from the transmission. Support the transmission with a transmission jack, remove the bell housing bolts per BMW torque specifications, and lower the transmission from the vehicle.
3. Old clutch removal: With the transmission removed, use a flywheel holding tool to prevent rotation. Loosen the pressure plate bolts in a star pattern gradually to release spring pressure evenly. Remove the pressure plate, clutch disc, and throwout bearing assembly.
4. Flywheel removal: Remove the OEM dual-mass flywheel bolts and remove the flywheel. Clean the crankshaft flange thoroughly.
5. New flywheel installation: Install the Clutch Masters single-mass steel flywheel onto the crankshaft flange. Apply Loctite to the flywheel bolts and torque to 88 ft-lbs in a star pattern.
6. Pilot bearing installation: Press or seat the new pilot bearing from the kit into the crankshaft center bore.
7. Clutch disc and pressure plate installation: Insert the alignment tool through the clutch disc hub and into the pilot bearing to center the disc. Position the disc against the flywheel with the transmission side facing correctly (markings typically indicate the correct orientation). Place the pressure plate over the disc and start all bolts by hand. Torque pressure plate bolts to 26 ft-lbs in a star pattern, tightening in gradual passes to seat evenly. Remove the alignment tool.
8. Throwout bearing installation: Install the new throwout bearing onto the transmission input shaft fork or hydraulic sleeve per your specific BMW setup.
9. Transmission reinstallation: Carefully guide the transmission into position, aligning the input shaft with the clutch disc hub. Torque bell housing bolts to BMW specifications (typically 35 ft-lbs for grade 8.8 bolts, 47 ft-lbs for grade 10.9). Torque guide tube bolts to 13 ft-lbs and slave cylinder to 16 ft-lbs.
10. Reconnect components: Reinstall the driveshaft, shift linkage, and all electrical connections. Reconnect the clutch hydraulic line and bleed the clutch hydraulic system if opened.
11. Break-in procedure: Perform a proper break-in by making 10 to 15 moderate starts from a stop, allowing the clutch to cool between cycles. Avoid aggressive launches or slipping for the first 500 miles.

Frequently Asked Questions

Does the Clutch Masters 03CM3-HD00-SK work with the OEM dual-mass flywheel on my BMW 330i?
No. Part number 03CM3-HD00-SK is designed to be used exclusively with the Clutch Masters single-mass steel flywheel included in the kit. It is not compatible with the factory dual-mass flywheel. Attempting to use the OEM flywheel with this kit will result in improper fitment and potential failure.

Can I use the 03CM3-HD00-SK on a turbocharged or supercharged BMW?
No. The FX100 series, including the 03CM3-HD00-SK, is engineered for naturally aspirated engines with bolt-on modifications only. For forced induction applications such as a turbocharged or supercharged E90 or E46, Clutch Masters recommends moving to the FX300 series or higher to handle the additional torque.

Is the clutch pedal noticeably heavier after installing this kit?
Pedal effort is only slightly increased over the stock clutch. The FX100 Power Plus I pressure plate is designed to provide enhanced clamping force while maintaining a near-stock pedal feel, making it very comfortable for daily driving, commuting, and stop-and-go traffic.

Will installing this aftermarket clutch void my BMW warranty?
Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your vehicle warranty simply because you installed an aftermarket part. The warranty on unrelated components remains in effect. Any dealer claiming a voided warranty due to this clutch installation alone would be in conflict with federal law. Consult a qualified attorney if you have specific warranty concerns.

Does the 03CM3-HD00-SK fit the 2005 BMW 330Ci with the E46 chassis?
Yes. In addition to the primary fitment of 2005 through 2007 BMW 330i E90, this kit also fits the 2005 and 2006 BMW 330Ci on the E46 platform as well as the 2005 BMW 330xi E90. Always confirm your transmission is a 6-speed manual before ordering.

What kind of break-in procedure is required after installing the FX100 clutch?
After installation, perform 10 to 15 moderate starts from a full stop and allow the clutch to cool between cycles. Avoid aggressive launches, heavy slipping, or aggressive downshifts for the first 500 miles. Proper break-in seats the friction disc against the flywheel and pressure plate surfaces, ensuring full holding capacity and longer service life.

Does this kit include the flywheel bolts?
The kit includes the clutch disc, pressure plate, throwout bearing, pilot bearing, alignment tool, and the steel flywheel. For flywheel bolts, Clutch Masters recommends using new OEM-specification hardware. Apply Loctite thread locker and torque to 88 ft-lbs in a star pattern during installation.

Can the 03CM3-HD00-SK handle a nitrous oxide setup?
Yes. The FX100 is rated for up to 50 horsepower nitrous oxide systems on non-forced induction platforms. If your N2O system exceeds 50hp shot or is combined with forced induction, a higher-rated Clutch Masters kit is required to safely manage the additional torque load.

Is professional installation required for this clutch kit?
Clutch replacement on these BMW models involves transmission removal and precise torque specifications. While an experienced home mechanic with proper equipment can complete the job, professional installation by a qualified technician is recommended to ensure correct flywheel torque, proper clutch alignment, and hydraulic system integrity.

How does the Clutch Masters FX100 compare to the OEM clutch on the BMW 330i?
The FX100 03CM3-HD00-SK provides 70% more holding capacity than the factory clutch while replacing the failure-prone dual-mass flywheel with a durable single-mass steel unit. Despite the significant capacity increase, it retains a smooth, near-stock engagement feel appropriate for daily street use, making it an ideal upgrade for enthusiasts who want meaningful performance without sacrificing drivability.
