Rogue Engineering Front Control Arm Bushings - BMW E46 M3

Rogue Engineering Front Control Arm Bushings - BMW E46 M3 - Suspension - Studio RSR
Product Description

After much R&D and testing, Rogue Engineering is proud to introduce its Performance Front Control Arm Bushings (FCAB).  A unique combination of CNC'd 6061-T6 aluminum and high performance urethane, we can now offer a bushing that is performance oriented enough for the track junkie yet without significant increases in NVH when used on the street.

Factory bushings are more than adequate for street driving.  However, when the miles start to pile up, the bushings are meant to be replaced.  Common side effects of worn factory FCABs include, but are not limited to the following:

  • Steering wheel shutter when brakes are applied
  • Wheel (and steering wheel) shimmy
  • Mysterious and irregular tire wear
  • "Overboosted" steering feel (very light steering)

Replacing factory bushings, with new factory bushings will return the factory feel.  However, we offer something that gives you MORE.

RE Performance FCABs
With the numerous delrin/urethane/hybrid replacement bushings in the market, we vowed to make something that was not only effective, but simple.  No clips, no washers, no multiple sleeves, no "race parts in street cars".

Some of the feature benefits of our Performance FCABs include:

  • Serviceable/rebuildable (replacement of bushing insert)
  • Urethane insert prevents unwanted control arm deflection while allowing NVH isolation
  • Eliminates steering shimmy and wander, especially with the addition of big brake upgrades
  • Unchanged steering geometry
  • Direct "connected" feeing with front end of vehicle
  • Easy to install (professional installation recommended)

In our development, we were able to limit the amount of bushing deflection while also controlling the amount of NVH being transmitted through the bushing itself by the durometer of the urethane insert.  We discovered that increasing the durometer stiffness (to nearly the harness of plastic or Delrin), we were able to limit the movement of the bushing so that it didn't move at all.  However, we got too much NVH to be used in a street driven car.  When we reduced the durometer too much, we had a very comfortable bushing, with stock-like performance.  Of course, with our goals, we were looking for performance one could live with everyday. 

 

Installation Notes

Access to the underside of the vehicle is required and professional installation is recommended.

The RE Performance FCABs reuse the factory "lollipops", as the aluminum sleeve of the FCAB is pressed into place (hydraulic press is required for removal of stock bushing and installation of RE FCABs).

Non-E46 M3s had both 66mm and 60mm ID housings.  Most standard E46 vehicles produced before 2/01 used 60mm ID housings.
