Performance
Drivetrain
Whether
you are a seasoned racer or
a week-end track junkie, drivetrain upgrades are
probably among one of
the most
satisfying any car owner can do this side of forced
induction.
But even a stock car can benefit from lightweight
flywheel and Quaife
ATB
differential will come handy not only when flying
through the corners
at your
next track day, but will provide needed power and
traction to the
slipping wheel
during those skiing trips.
Quaife ATB Differential (return to top)
The Quaife Differential powers both
drive
wheels under nearly all conditions, instead
of just one. With an
ordinary open differential, standard on most
cars, a lot of precious
power is wasted during wheelspin under
acceleration. This happens
because the open differential shifts power
to the wheel with less grip
(along the path of least resistance). The
Quaife, however, does just
the opposite. It senses which wheel has the
better grip, and biases the
power to that wheel. It does this smoothly
and constantly, and without
ever completely removing power from the
other wheel.
The Quaife's unique design offers maximum
traction, improves handling
and steering, and puts the power where it is
needed most. A definite
advantage whether on the track or on the
street.

Engineering Finned Differential Cover

What
happens when you use a
stock differential at the track, even at
a simple driver
school? With a single 30 minute
track session, a driver with
average ability can increase the
temperatures in a stock differential,
causing the fluid to start seeping out
of the vent hole. By
doubling the capacity of the amount of
differential fluid, as well as
adding much needed cooling fins, the
differential is allowed to
function properly, within the factory
specified temperature parameters.

Underdrive Pulleys
(return to top)
As
most know, the heart of every BMW is its
engine. When you
blip the throttle to ask for power, the
engine responds with the power
that BMW designed into it. Well,
almost all of the power.
The engine is also asked to drive specific
accessories in the vehicle
such as the A/C compressor, alternator,
power steering pump and water
pump. All of these crank
pulley driven
accessories inherently affect the engine's
efficiency.
UUC's underdrive pulleys reduce parasitic
drag by reducing the speed of
the water pump and power steering pulleys
relative to the crank pulley
speed. Each pulley set includes two new
accessory pulleys and a new
special length drive belt.

Transmission Mounts
Enforcers (return

The
most effective, bang-for-the-buck upgrade
just got better!
In the past, simply using transmission
mounts from a 320i provided some
benefit when used in late model BMWs. By
developing the Tranmission
Mount Enforcer (TME), it increases it's
effectiveness substantially,
without ill effects. Installation is
rather painless and the benefits
are tremendous. With the overwhelming
popularity of our Tranny Mount
Enforcers, we decided to improve the
system even more.
By working with a vibration control
company, they have been able to
produce a custom vibration mount designed
to work specifically with the
TME. However, by specifying specific
design parameters with the mount,
the most effective upgrade just got
better. By maintaining the
vibration dampening and deflection
properties of the 320i mount and
incorporating minute changes for use with
the TME, you have an upgrade
that has no equal! No vibration, no
modifications to the car or
driveline, no change in height of
transmission bushings.

"Big Boy" Clutch Stop (return to
top)
The
advent
of an adjustable clutch stop lets the driver
specifically set
the ideal point of reference where the
clutch pedal stops just after
the clutch mechanism disengages. Therefore,
once set properly, the gas
pedal may be applied immediately after the
clutch pedal is released.
This lets the driver shift with one less
item to worry about, actually
forcing them to become smoother. The clutch
stop works on many BMWs
(including the new E46 modelswith slight
modification to the
clutch-sensor switch).

Clutch Arm Bushings
(return

Quite
simply, it is well-known that BMW's original
clutch arm bushings are
the culprit for these annoying
problems.
By simply replacing the stock bushings with
the UHMW (Ultra High
Molecular Weight polycetal) UUC Motorwerks
Clutch Arm Bushings, you can
permanently get rid of that annoying squeak
and the side-slop.

Red
Line Synthetic Gear Lubricants (return

| Red
Line
Gear Oils and Transmission Lubricants are
designed to provide
excellent low-temperature shiftability and
improved gear protection at
higher temperatures. Red Line Gear Oils will
reduce differential
temperatures 10-70°F. Efficiency
improvements between 1-5% are
typical. The synthetic base stocks used have
tremendous thermal
stability and provide the best film strength
available. The unique
combination of base stocks and additives
allow Red Line gear and
transmission oils to carry higher loads
compared to petroleum
lubricants. The stability of these products
allow them to be used for
extended periods. |
