BMW Control Arm Replacements & Upgrades for BMW 3 Series E46 (1999-2005)

Factory bushings are more than adequate for street driving on the E46 M3. However, once 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 with new factory bushings will return the factory feel. These urethane core bushings, however, offer something MORE. These bushings are designed to deliver performance that surpasses the stock E46 M3 bushing, while still allowing them to be used in everyday driving scenarios on public roads.

With the numerous delrin/urethane/hybrid replacement bushings in the market, we wanted to offer bushings that were not only effective, but simple. No clips, no washers, no multiple sleeves, and no "race parts in street cars". They have an aluminum outer sleeve with a replaceable, compliant urethane core that is serviceable and rebuildable. These urethane inserts prevent unwanted control arm deflection, while allowing noise/vibration/harshness (NVH) isolation -- a must on any bushing being used on a street driven car. And because of their compliance they remain very comfortable for daily use. But because they are a heavier-duty design than stock, these eliminate steering shimmy and wander, especially with the addition of big brake upgrades. They maintain BMW's original suspension geometry, and give your M3 a directly "connected" feeling with the front end of the vehicle. Perhaps best of all, these bushings are easy to install and are designed for longevity. Professional installation on suspension components is always recommended.

Installation Instructions

This item fits the following BMWs:
2001-2006 E46 BMW M3

This package covers the front control arms and bushings on the 2001-2005 E46 325Xi and 330Xi. These cars use a unique front suspension but the principle design and downside, is the same as almost all of the BMW 3-series since 1984. The inner and outer ball joints see a lot of wear as they are constantly in motion. With the heavy front end of the 4WD Xi, these components need frequent inspection and replacement. When the bushings and ball joints fail, the front end can shimmy and feel loose through the steering wheel. Excess play in the rubber bushings can cause alignment problems and sloppy steering. There is usually a knocking or clunking sound to further annoy you. We've assembled thispackage to replace everything on both front control arms and restore your BMW's exceptional driving dynamics. All parts are OEM Boge, Lemforder, or Original BMW to maintain the highest quality standard.

This kit includes the following parts:

• LEFT FRONT CONTROL ARM, part# 31126758533 / 31 12 6 758 533
