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 SPL BMW G2X Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the G2X BMWs (M340i, M440i, etc) while eliminating bushing deflection resulting in sharpened steering response and driving precision. The ability to run more negative camber and a slightly wider track width greatly improves the peak lateral grip available. This is especially important with better tires and a must-have for anyone looking to prevent excessive outer shoulder wear (and heating) on their tires due to a lack of camber. The lower control arms come with a ride height sensor bracket to maintain factory ride height sensor location, regardless of length of the arm to keep those finicky BMW chassis electronics happy. Suitable for all uses, from daily driver to race car.

Control arms 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.

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.
