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

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.

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.

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 weren’t 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 “race-only” 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.

Made in the USA If you haven't already upgraded to Adjustable Camber Arms , your stock rear lower wishbones are letting your down. The stock rear camber arm/wishbone is designed to be flexible and weak. In an impact, it's designed to bend or even break to absorb energy and prevent damage to other more vital components. This is great on a regular street car. But on a track car, or heavily modified street car, these arms can bend just from cornering forces and that can introduce radical camber changes that will throw off the balance and handling of the car. This reinforcement solves all of that by tying the two sections of the arm together. This creates a single solid arm with minimal flex in the arm itself. We can't take credit for this innovation - BMW recognized the problem and did this on their factory Group N racecars. If you haven't made the jump to adjustable arms, or your racing class still requires the stock camber arm, then this kit is a must! Installation requires welding.

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.

Made in the USA TMS rear subframe bearings are designed to limit rear control arm movement relative to the subframe. The stock BMW subframe bushings are made out of rubber, which allows variance in suspension position due to deformation and compression. A race car needs to have all suspension points remain in place for proper setup. By using high grade aircraft aluminum alloy and high performance race bearings, the TMS bushing replacements are both lightweight and strong. The casing is designed so that if maximum motion occurs, the load will be evenly distributed throughout the casing. Our flanges are designed to spread the load on the subframe and limit movement. The bearing we use is an extra wide race bearing to distribute the load over a broader area. Each piece is anodized or nickel plated to withstand corrosion. These bushings are a perfect compliment to the TMS lower camber arms.
