A great
upgrade for drivers looking for added acceleration and grip for
their E46 M3.
Changing your cars gearing is one of the most
effective performance improvements you can make for the money. For
example, swapping from a 3.15 to 3.46 ratio will give your car 10%
more torque delivered to the rear wheels! All of our differentials
are limited slip units, meaning that both wheels pull - no more
wheel spin. We will exchange your current differential for a unit
built exactly to your specification. We have every ring and pinion
ratio available including extra-short Motorsport ratios.
We have 6 different types of limited slip units
available to suit your particular needs**:
-
M
Variable - The torque-sensitive, variable M differential lock
identifies exactly when traction is needed. Even when wheel grip
varies enormously, such as on bends taken at high speed,
roadholding remains excellent as the locking power between the left
and right rear wheels can be raised to 100%.
-
2 Clutch - Based
off the factory limited slip carrier, this unit is great for street
use and is easy on the wallet.
-
3 Clutch - This 3
clutch unit is designed to further increase the locking abilities
of the differential for more aggressive traction and grip. Great
for street cars seeing numerous track days per year.
-
3 Clutch with Custom Engaging Ramp Angles
- Our best selling carrier type. The
carrier incorporates custom ramp angles built into the carrier for
an engagement that is more substantial and track oriented. This
unit offers excellent turn-in and the abilities to lay down some
serious power earlier during track-out. The unit has proved to
greatly reduce track times and as a result, created some very happy
customers!
-
Quaife - Unlike a
conventional plate-style limited slip differential, the Quaife
Helical LSD differential relies on gears rather than clutch plates
for its operation. The Quaife helical LSD never locks harshly with
a set pre-load of wheel slip across the driven axle. Rather, the
Quaife Helical LSD automatically biases the torque away from the
spinning wheel across the axle to a constantly varying degree,
never locking completely.
-
OS Giken - The
increased number of friction discs not only dramatically improved
the LSD's locking force, it enables it to lock fully and
completely. An added benefit to being a fully locking mechanism is
that less heat is generated, thus resulting in incredible
durability and reliability.

**Selecting the best differential type for your
application can be a difficult task considering the amount of
ratios and limited slip carriers. Please feel free to contact your
BimmerWorld sales representative to discuss the best differential
for your application.
***The ability to rebuild the returned
differential will be decided by the differential
builder.
