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 M3.
Second-generation "Stage
2" technology now available for E46 M3.
Tipping the scales
at only 8.5lbs, this aluminum flywheel boasts the same great features as our
first-generation flywheel, but is designed to use the pressure plate,
and throw-out bearing from the 3.6 liter E34 M5 and UUC's own sprung-hub
clutch disk (available in different materials depending on intended use).
Big news for E46 M3 owners!
Many E46 M3 owners 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 M3 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 M5
component 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 design for use on the powerful
S38-series engine in the M5, it is up to the task of handling the output from
the M3's S54 motor.
UUC customers
have been using the Stage 2 & M5 clutch setup in turbo or supercharged
E36 M3s and MZ3s with fantastic results. Our own testing has shown
the M5 clutch to reliably handle in excess of 450hp with a standard
organic disk.
The UUC Stage 2 flywheel and clutch assembly has been used in the
"test platform" M3 of Eurosport High Performance's
supercharger development, reliably handling many miles and dyno runs in
this powerful machine. |
The total weight of this clutch disk and pressure plate
combo is greater than that of a standard E46 clutch, so we have reduced the
flywheel weight to achieve an overall rotating mass that is almost identical
to a standard 11.5lb lightweight flywheel and 3-series clutch combination.
You can be assured not only of the performance increase you will experience,
but the long-term ease of ownership that comes with knowing that replacement
clutch components are never any further away than your dealer's parts counter.
Ideal clutch combination is the E34 M5 pressure plate and UUC sprung-hub
clutch disk, although standard fixed-hub E46 M3 clutch disk (emergency
repair) may be substituted - increased gear rattle will result.
