| Rogue Engineering just
like all their products, spend countless hours on research and
development, designing these rear trailing arm bushings (RTAB) to out
perform any other bushings on the market. Rogue did not just stop
there with design but took it further to create a new material that has
the capabilities of both a smooth squeakless ride as well as having the
ability to take anything a track junky can dish out.

Rogue
Engineering RTAB's
Fits the following vehicles:
- All E36, including M3. Does
NOT fit Z3 and 318ti.
- All E46, including M3.
Professional Installation Required
- Because the RTAB "console" removal
is required, an alignment is recommended. For installation of the
part itself, it is very straightforward, but requires some special
tools

Rogue Engineering Urethane RTAB Bushings
Because of the unique design,
installation of the bushings is much easier than factory bushings.

Problems with Factory Mounts
The factory BMW RTABs
(Rear Trailing Arm Bushings) are a very soft material to
provide the quietest, most comfortable ride possible. Because
of this, Rogue Engineering has seen factory mounts require
replacement in less than 50,000 miles and 3 years. On modified
vehicles, expect them to require replacement sooner.
Are your bushings already shot?
A simple test to determine if the stock rear trailing arm
bushings require replacement is driving the vehicle in a
straight line. While in gear, under full acceleration, does the
car pull to one side? Additionally, under full, firm
application of the brakes, does the car pull again? If you
answered yes to either one, the bushings probably require
replacement. Factory bushing from a 3 year old, 25,000
mile vehicle.
Rogue Engineering Performance RTABs
The bushing material used in Rogue Engineering Performance RTABs
are now available in two different compounds, specifically for
your needs. Both compounds now incorporate a silicone
impregnated, polyurethane compound. The biggest different being
the hardness of the material. |

|
BLACK |
This compound is formulated for
STREET applications. Softer than Rogue Engineering blue,
TRACK compound, these are stiffer than stock factory OEM
bushings and designed to last much longer than stock. Since
these are the great compromise between OEM and Rogue
Engineering TRACK bushing. Engineered to approximately
Shore A 93 hardness. |
|
BLUE |
This harder compound is designed
for TRACK applications, where monoball components are not
allowed. Less expensive than full Delrin bushings, these
bushings are extremely stiff to provide the absolute maximum
performance at the TRACK. Purposefully engineered to
approximately Shore D 65 hardness. |

This hardness is important in this
bushing especially in modified vehicles, since they will exert more
force on the rear suspension during acceleration.
The inner sleeve that supports the
bushings is made from 6061-T6 aluminum, CNC'd to exacting specifications
for a perfect fit, here in the good 'ole USA.
Do NOT confuse these
bushings with bushings produced outside of the US, with unknown material
with questionable hardness. Rogue Engineering has installed similar
bushings produced by other companies which are simply too soft. In
these cases, it would have been better if stock bushings were used since
it allows too much movement of the rear trailing arm.

Tired of the Squeaking?
Rogue Engineering's manufacturer has offered Rogue Engineering a
silicon based formula, to also keep the urethane bushings quiet during
use. Approximately 1.3 oz. of silicon is poured into the mold, which
means that it is permanently impregnated into each bushing. This
process costs more to produce, but Rogue Engineering feels that it makes
for a better product in the long run.

A common downside of the urethane
bushings over stock rubber ones was that they would typically develop
noise over time (or even right away). These noises were from a
combination of the harder material, inadequate lubrication (or none at
all), and the contact with the factory steel mounting hat rubbing
against the bushing.
A new, exclusive feature now incorporated
into the Rogue Engineering RTABs is Rogue Engineering new machined
"grease trap". You can see this "grease trap" (picture 1), which is the
small area around the end of the aluminum pin. This allows for
lubricant to be remain captive during the installation of the bushings
(picture 2) instead of being scraped off by the factory steel mounting
hat. Rogue Engineering is the only company on the market to introduce a
novel solution such as this to reduce the noise without sacrificing the
performance. If your have any
