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. The ball joints on the M3/M4 wishbone give a more precise feel and allow the control arm to move freely without resistance and with minimal deflection. 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.

Genuine BMW
This is the factory BMW control arm upgrade 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. Alternate part number 31122282121.
