"Moderate lightweight" flywheel and clutch combination for the
E39 M5 and Z8 provides reliable clutch operation without
excessive weight reduction. Excessive weight reduction causes the
dreaded "transmission chatter" (also known as "gearbox rattle" or
"rollover noise").
With the "moderate lightweight" flywheel, a significant performance
improvement is still realized but with minimized gearbox rattle... and
all at a reasonable cost!
PRICING OPTIONS (complete kit including flywheel, clutch components
chosen, all hardware, ignition timing plate):
| 1)
Performance Organic clutch - high performance street/track use with
greater clamping force and torque capacity. |
|
| 2)
UltraSmooth CeraMetallic clutch - ultra-high performance street/track
use with greater clamping force and torque capacity (recommended for
"street drag racing" and highly modified / supercharged cars). |
|
The design of the "moderate lightweight" flywheel and clutch for the
BMW V8 had to combine all of these characteristics:
- 13.5lb reduction is flywheel weight
for faster acceleration and better throttle response.
- No change in clutch feel or pedal
effort.
- Custom clutch with SAC elimination
- extends durability of clutch to eliminate the unnaturally short
lifespan of the original BMW design.
- Clutch features "sprung hub" center
for power pulse variation damping, an additional noise reduction
technique.
- Quiet operation with minimal gear
lash sound.
- Power-handling capabilities
suitable for the original 394hp rating of the M5 with options for
greater power levels.
- Readily-available replacement
clutch offerings.

THE CLUTCH:
The clutch is from the well-respected
and race-proven line of UUC performance clutches. The "Performance
Organic" disk proves normal original equipment clutch feel and
smoothness with added power capability. The "UltraSmooth CeraMetallic"
is designed for the "warmed up" M5 or for more "enthusiastic" drivers.
One pioneering feature in all UUC clutches is the elimination of the
"SAC" (Self Adjusting Clutch) mechanism that has been so problematical
in the original equipment clutch. By using a conventional-style
pressure plate, durability and enhanced clutch feel are realized.
In addition to the improved materials and design, this clutch features
a sprung hub center section that damps the power pulse
variations that cause transmission rattle in standard fixed-hub
clutches. Combined with the specific weight of the UUC flywheel, the
result is a lightweight flywheel/clutch combination that is rattle-free
in most installations (variations in transmission wear, condition of
fluid, and other factors may cause some cars to experience very slight
rattle).
- "Performance Organic" clutch
kit with performance clutch material, pressure plate with even greater
clamping force. Rated beyond 500lb-ft.
- "Segmented Kevlar"
clutch kit with higher performance clutch material, pressure plate with
even
greater clamping force. Recommended for harder use or those with
greater power modifications.
THE
FLYWHEEL:
Built with the same level of technical
sophistication and quality that earned UUC a European Car magazine
"Select Gear Top 10" award for best products of 2003, and also the SFI
race-spec certification, this is simply the best quality flywheel that
can be built. Construction details include CNC machined 6061-T6
aluminum disk with replaceable 1050 steel friction surface (suitable
for any clutch material, including race-only sintered iron). Friction
surface retaining bolt pattern is computer-designed for optimum
strength and load-bearing. Correct V8 starter ring and ignition trigger
ring for perfect operation.
HOW
WELL DOES IT WORK?
It works flawlessly. Clutch effort is
identical to the original V8 clutch, and feel is even better. With the
specific weight and sprung-hub clutch design, typical transmission
rattle is dramatically reduced or even nonexistent in some
installations. With a significant 13.5lb weight savings in rotating
components compared to the original flywheel/clutch package,
acceleration and throttle response is noticeably improved.
