BMW Control Arm Replacements & Upgrades for BMW E46 (1999-2005) M3

Clear BMW chassis
Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. They do more than just keep the alignment in a constant spec - they are a vital locating component for the suspension itself. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals.

Most control arms for BMWs consist of an inner and outer ball joint made of plastic, rubber, Delrin, or metal and covered in grease with a rubber boot to seal it from the outside. The ball joint rotates and spins as the control arm goes through its movements and that will wear the ball joint and make it loose. The grease inside the housing can also get used up, evaporate, or become contaminated from moisture and foreign particles. As the ball joint becomes worn it can result in excess movement within the housing. Your steering and handling will become less precise and there is usually a light clunking or clicking sound. In rare and extreme cases the ball joint can separate from the control arm completely, leading to a total loss of suspension and steering control. You should have the ball joint play checked annually and replace them every 3-4 years. Most track organizations will not allow a car if they are older than three years.

Control arms also take abuse from impacts and handling forces. Aluminum control arms will generally bend and prevent an accurate alignment. Steel control arms will crack and fracture and require close inspection annually and replacement every 3-4 years.

We sell OE BMW, OEM, and performance upgrade control arms from proven manufacturers. The control arm is so important to a BMW suspension that we insist on only top quality brands and designs and will never sell a control arm based on price alone. We also have upgrade packages with superior designs and better bushing options and we have bundled these together with valuable package savings.

Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011). We wanted to offer e30, e36, and e46 owners similar levels of handling precision and control for the track and street, but werenaEURtmt satisfied with the other options out there. Instead of a Delrin bushing or unsealed spherical bearing alone, we selected an oversized sealed greaseable spherical monoball to offer unparalleled durability and precision, but designed a Delrin adapter sleeve to help isolate the added noise, vibration, and harshness that a full solid monoball bearing will have. While race-ready, our hybrid Delrin/monoball control arm bearings are more at home on the street than other kits that are advertised as aEURoerace-onlyaEUR bearings. We did extensive street, autocross, and track testing to ensure the spherical bearing used in this bushing design excelled in each setting.

The stock rubber bushings, even those found in the M3, allow significant fore/aft movement of the front wheels to help absorb road impacts, especially when being pushed hard. This soft flexible design maximizes daily driving comfort, but also allows considerable alignment change. This unwanted deflection stands between you and a crisp, confidence-inspiring driving experience. The advantage of a monoball bearing is that it will not deflect under load, eliminating all unwanted deflection while still allowing complete freedom of movement in the desired angles. What you get is superior steering precision with better handling from more consistent alignment and direct braking feedback, with exceptional service life. Thanks to the Delrin insert and double lip seals, there's none of the extra noise or reduced service life often found on other spherical bearings.

In short, if you're seeking front control arm bushings that offer precise, predictable handling, crisper braking feel, with a long service life free from noise - look no further. We have you covered.

Here at Turner we understand the importance of an upgrade that will get the results you need on the track and still be tolerable on the drive around town. When it comes to control arms on the track, making them as stiff as you can (usually using solid mounts) is the best way to increase your driving precision by eliminating the deflection of rubber. The next best thing to create a balance would be to stiffen up the control arm with polyurethane, giving you the option of a more stock like feel with 80a or closer to the solid feel with 95a durometers. These poly bushings will give your control arms a direct connection between your suspension and the body of the car eliminating the slop felt under take-off and braking so you feel more in control of your vehicle.

*Featuring a delrin sleeve to eliminate heat deformation and premature failure.

This item fits the following BMWs that use a centered-style bushing:

Top seller! The Turner Adjustable Rear Camber Arms: The Only Adjustable Arms Approved for Grand-Am Continental Tire Challenge Racing Series

Why you should use Turner Motorsport camber arms on your car:

  • If you have a lowered car and have run out of adjustment with the stock camber arms.
  • If you have a track car and are looking for increased camber adjustment, light weight pieces, stronger components, and improved suspension handling
  • Two bushing styles to meet your needs: solid rod-end for track-only use, or rubber bushing for mixed street/track use (approved by Grand-Am!)
  • The high range of adjustment allows a full racecar setup or a heavily lowered car to maintain factory specifications.
  • Only high quality and high strength materials and components are used
  • Aluminum camber arms are designed as a lightweight component, thereby reducing wear and tear on other, more critical parts (rear subframe, control arm bushings, etc). Each camber arm weighs only 2.5 lbs making for a total of 5 lbs for both parts! Stock camber arms weigh 3 lbs each. We have seen competitor's arms that weigh twice as much!
  • Hardcoat anodized aluminum, stainless steel turnbuckles, and stainless rod ends to all but eliminate corrosion from getting into the threads and making adjustment difficult.
  • CNC-machined double shear design for ease of installation, high strength, and choice of outside bushing material. But we do suggest using with (outer bushing # 33326775551) for best performance.
  • Easy adjustment - our main adjustment point is on the outside by the wheel so there is no need to work around the exhaust or subframe to adjust camber.
  • All hardware included.

This E46 M3 front control arm is a direct replacement for the original part and is the OEM Lemforder brand.

Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.

We also recommend replacing the bushings when changing the control arms. The bushings are mounted at the back of the control arm and located the arm to the frame rail on the car. The stock bushings are rubber and will wear out sooner than the control arms themselves. With the control arm off the car now is the perfect time to also replace the bushings.

E36/E46/Z4, including M models, rear lower control arm (camber arm, wishbone). This is a direct replacement for the stock arm and includes the inner bushing. These arms are designed to be slightly weak and flimsy as they will absorb impact energy. It's better for this arm to absorb an impact rather than the wheel or trailing arm, or subframe, etc. Also, unknowing tow truck drivers like to use this part to hook their chains on to. Consequently they bend as easily as a coat hanger. An OEM replacement from LemfAPrder is the perfect option to restore control and suspension quality.

There's finally an option to buy housings separate from the bushings, this way you don't have to live with the stress placed on the stock housings when pressing the old bushing out. The biggest benefit come in when there isn't already a pre-pressed in option for poly and spherical upgrades, this leaves the only option of pressing the old bushings out. Through out in-house testing when designing our poly and spherical upgrades we noticed that pressing the bushing out caused stress in some cases creating hairline cracks in the housing leaving it vulnerable to failure.

The rear trailing arm bushings take a lot of abuse from accelerating, braking and cornering. The stock rubber bushings are just not up to the task of keeping rear wheel alignment in spec for very long, especially if you have upgraded to stickier tires and a better suspension. The pliable rubber flexes and twists which slows down reaction time and leaves you with a car that feels nervous and 'tail happy'. Urethane helps to control the alignment but issues with fitment, maintenance, and longevity keep us from recommending urethane on anything but a street car.

The Monoball bushings from Dinan are the perfect option for heavy tack use and extended longevity. These don't allow nearly the same amount of deflection as other bushing styles and give your a significantly tighter feel in the rear of the vehicle when driving aggressively.

Benefits:

  • Improved Steering Responsiveness
  • Reduces Brake Shimmy
  • Nylon-lined Bearings for Quiet Operation
  • Machined Aluminum Housings+ Sealed Bearings

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their aEURoetotal packageaEUR approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere.
