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 (return

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
to top)
| 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. |
