Ultimate throttle response and faster acceleration at your command...

UUC's unique "sprung hub" clutch design Stage2 lightweight flywheel has been named one of European Car magazine's "Top 10 Products" for 2003 in the E36 fitment.  Now the same technology is available for the E46 330i/Ci 6-speed, Z4 3.0, and '03+ 530i.

Second-generation "Stage 2" technology now available for the E46 330 6-speed and SMG.

This aluminum flywheel boasts the same great features as our first-generation flywheel, but is designed to use the pressure plate from the E36 M3 and UUC's custom sprung-hub clutch disk with a choice of various performance facings.

Big news for E46 owners!

Many E46 owners (330, 328, 325, 323 models) have experienced mushy clutch feel, inconsistent engagement, and premature wear of the clutch in their manual-transmission cars.  The reason is quite simple - the original BMW (LUK-manufactured) clutch in the E46 (and E39) has a new "SAC" (Self Adjusting Clutch) design.  This new mechanism built into the clutch pressure plate is supposed to keep the clutch pedal engagement point the same as the clutch wears... but in all reality, it's a case of  "an answer to a question that nobody was asking." They have added a layer of complexity and feedback isolation, filling a need that didn't need filling - it is not too often that anybody notices that their clutch engagement point as moved 1/2" over 50K miles.

The SAC mechanism itself causes problems; it over- or under-adjusts the pressure plate and therefore causes the clutch to slip or burn out prematurely. They are also known to shift, causing the pressure plate release fingers to slip off the plate, keeping 1/3 of the pressure plate engaged at all times. Bottom line is that the only fix is a complete clutch job, and your dealer is likely to claim "driver abuse". We have seen it happen too many times.

The SAC mechanism may not give a clean release like a standard clutch. Instead of just two sets of springs, there is an adjuster mechanism that makes engagement feel mushy or slow.

The M3 clutch conversion eliminates the SAC mechanism and restores traditional clutch feel with predictable and crisp engagement.

This clutch has several advantages for the enthusiast driver: 

• Maintaining the reliability and over-the-counter availability of a BMW factory part.
• Greater clamping force than standard 3-series clutch.
• Elimination of the SAC mechanism.
• Incorporates a sprung-hub design for quiet operation with a heavy-duty steel pressure plate.

The advantage of a sprung-hub clutch design is improved resistance (and in many cases, complete elimination) of the residual chattering noise at idle that some lightweight flywheel-equipped cars can experience.

Because BMW spec'd this clutch for use on the powerful S52 engine in the M3, it is up to the task of handling the output from a modified 330i/Ci motor.
