Genuine BMW BMW Control Arm Replacements & Upgrades

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.

The shock towers on the E36 and Z3 are notoriously weak. Under normal driving conditions with a stock, fresh suspension it is unlikely that you will ever have a problem. But with an upgraded street or race suspension with firm springs much of the energy from pounding the road is transmitted to the thin sheet metal in the strut tower. This pounding will cause the tower to deform or even crack. Look for 'mushrooming' or deformity around the holes for the three mounting studs at the top of the strut tower. The sheetmetal around the holes should really be flat and square. Poor shocks or stiff suspensions will actually cause this sheetmetal to pop up.

These factory BMW reinforcement plates will help disperse the energy and save you from costly repairs in the future. A strut brace also helps to prevent this but these plates are designed to reinforce the strut tower from the bottom. The install over your strut mount or camber plate and simply add thickness (strength) to the strut tower. They can be sandwiched in place and do not require welding. BMW part number 31312489795

This is the left front lower control arm (also called a wishbone by BMW) for the F80 M3, F82 M4, and F83 M4. This can also be used as an upgrade on the F22 2-series and F3X 3/4-series. The M3/M4 control arm features a sealed inner and outer ball joints that are superior to elastometer rubber.

When used on the F22/F30/F32 3/4-series they all 0.5 more degree of negative camber by pushing the bottom of the wheel out. And these are a little bit lighter than the stock F22/F3X control arms. This is a an ideal upgrade for track and autocross cars that need more negative front camber.

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.

This item fits the following BMWs:
2006-2008 E85 BMW Z4 M Roadster M Coupe
