BMW Suspension Parts for BMW Z4 M Roadster S54 (2003-2008)

This ball joint is used for the upper rear trailing arm bushing on ALL E36, E46, E83 X3, and E85 Z4 cars. BMW also used it as the lower bushing on most M cars. It makes a great upgrade on all non-M cars where BMW used a rubber bushing at the lower position.

This sealed ball joint is one of the best things about the rear suspension - it functions extremely well and lasts a long time. And it can be used as a replacement for the existing bushing without any further modification. The non-M cars used a solid rubber bushing for the lower arm (camber arm, wishbone) which does not last very long and relies on bushing deflection (twist) during suspension motions. The ball joint inside the upgraded design is much more effective during this suspension movements as it does not bind or deflect. And because it's sealed with rubber it will last a long time and remain quiet and maintenance free. Most customers report that after installing or "upgrading" to these bushings the rear end of their car felt much more stable.

Price is per bushing. Left/Right and Upper/Lower are the same part.

This control arm upgrade was used on the high-performance 330i ZHP Performance Package and offered by BMW as a sport retrofit. These arms are identical dimensions as the regular arms so they are a direct replacement. But they have all metal ball joints instead of plastic or rubber. This means they last a lot longer and are much stronger. We used these in our Grand Am and World Challenge E46 racecars with excellent performance.

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.

Lemforder is the original equipment supplier to BMW for these control arms.

Sway bar end links connect the swaybar to the rest of the suspension, preventing body roll and keeping everything in line in tight turns. This exposes these links to a high amount of stress and pressure, often leading to split bushings and sloppy body control and knocking noises. OEM Lemförder sway bar links are the perfect option to restore body control and eliminate knocking noises.
