BMW Control Arm Replacements & Upgrades for BMW Z4 M Roadster S54 (2003-2008)

Clear BMW chassis

Please ensure your correct model is selected

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.

Lemforder
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.

OEM front control arm bushing (FCAB) as used on the E85/E86 Z4M.

The front control arm bushings are a key piece of the suspension. They are constantly in motion and take abuse from impacts, potholes, rough roads, and general cornering/wheel motions. To give a quiet and smooth ride, the bushings are made of compliant rubber. But the rubber can only withstand so much abuse before they become loose and spongy. This results in vibrations and possibly a shimmy when driving. A visual inspection will usually confirm that there is too much flex in the rubber or the rubber has cracked and torn. And if you're installing new control arms, always install new bushings to avoid duplicating labor costs.

These bushings come pre-pressed into their aluminum brackets. No need to press out old and press in new bushings! Just a simple swap! Sold Individually.

Condor's Offset Rear Trailing Arm Bushings (RTABs) are perfect for the street and the track. They're designed to help correct rear toe-in and toe-out issues on lowered cars. To correct for toe-in: RTABs can be installed with the thick side inboard to help push the rear trailing arms towards the outsides of the car. To correct for toe-out when running minimal camber setup: RTABs can be installed with the thin sides inboard to help push the trailing arms inwards. The amount of total adjustment is purely dependent on how low your car is, but we've seen toe adjustment from 1/8” out on each side to 1/8” in on each side, which is a super nice range for the e36 rear end! They use UHMW in all of their suspension bushings because it is self-lubricating, meaning it requires no grease when installing, has almost zero deflection yet also absorbs some vibration. It will outlast other types of rubber or urethane bushings. They include black oxide plated steel plates for each RTAB to prevent lateral movement between the bushing material and the aluminum. Polyurethane and rubber bushings will deflect and slide, causing your rear alignment settings to change mid-corner. With these bushings, you won't have to worry about dynamic changes in your toe settings; the rear alignment stays in check during hard cornering, braking, and acceleration.
