BMW Control Arm Replacements & Upgrades for BMW E92 M3 S65 4.0L

Clear BMW chassis

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 rear lower control arms on E82/E9X models are the weakest link in the rear suspension. The arm is made from folded sheetmetal and it bends and deforms easily. Not only will it deform from potholes and curbs, tow truck drivers love to hook onto them without realizing how weak they are. We have seen other race teams complete the box section to make them stronger. A bent arm will throw off the geometry in the suspension, potentially affecting handling and tire wear. These aluminum arms are both lighter and stronger than the factory sheetmetal arms and is the best solution for chronic bending of the stock arm. These are a direct replacement to your stock arms with no changes needed to your alignment. New high-grade hardware is included.

Note: the stock arm is designed from the factory to be intentionally weak. These arms will bend so that something else in the suspension does not break. Our race cars used the stock sheetmetal arm but we replaced them often. We found that it was better to finish a race with a bent arm than not finish due to a catastrophic failure. The ECS arms are still designed to be the weakest link but are far stronger than the factory arm and will not bend as easily.

*NOTE: ONLY FOR CARS WITH TRUE REAR COIL OVER CONVERSION - NOT COMPATIBLE WITH STOCK REAR SPRINGS* Fall-Line Motorsports has taken everything they've learned in manufacturing over the last decade to create an ultra-high-end interpretation of the G8X / F8X M2 M3 M4 and E9X M3 lower camber arm. Fall-Line's bespoke version discards the deformation-prone stamped steel arm that includes a provision for the rear coil spring in favor of 5-axis CNC machined, billet aluminum that eliminates the rear coil mount. This pair has been gorgeously crafted and pocketed (to save weight without compromising rigidity) and is hard coat black anodized for ultimate resistance to wear. So too has the hardware been given an upgrade—10.9 grade corrosion-resistant extended bolts are included to replace the inferior factory pieces. These arms represent another exciting entry into the often neglected F8X / E9X suspension arm market and add valuable peace of mind for street or motorsport duty from the undisputed champion within the BMW realm. Product Details: For all G8X, F8X, and E9X M3 cars using TRUE Rear Coil Over Conversion ONLY DMG Mori 5-Axis CNC machined, billet aluminum construction Hard coat black anodized Includes Camber Shim Set Sold in pairs

A byproduct of multi-link suspension arrangements is a dynamic change in the car’s alignment settings- when making an adjustment to one attribute like camber, track width and toe will follow. This is especially true for the E9x cars, as the original BMW camber eccentric bolt has an impact on toe as well. Alignments are made faster and simpler when using a set of aftermarket lower arms, enabling the alignment tech to easily reset toe after adjusting camber. The standard toe link kit by Fall Line Motorsports is designed to simplify toe changes at an alignment facility while still keeping cost reasonable. The standard toe link kit keeps costs down by using a traditional jam nut design in a sturdy billet arm. Adjustable threaded rod ends turn into and out of the arm for a wide range of toe adjustment, and enable an alignment technician to easily set toe on a lowered car.

Rubber bushings found in the latest M Cars' rear camber arms are the last weak link in an otherwise rigid suspension. Fall-Line's new lower control arm bearings yield a significant improvement over the factory bushings; as motorsport parts, both strength and longevity were priorities—to do just that, Fall-Line boasts the largest FK spherical bearings on the market—by eliminating rubber from a critical feedback area of the car, you gain control over the tire’s behavior and thereby confidence behind the wheel at the limit. To adequately cope with competition-level load, Fall-Line bearings feature stainless steel spiral locks that offer 360 degrees of clamping force to secure the bearing from any potential movement.

Fall Line’s mono ball spherical bearing conversion kit transforms the front steering and suspension feel of the M3. The factory rubber bushing is very large, and is prone to substantial deflection under load, as the M3 is put through its paces. Deflection of the bushing can create unwanted geometry change, steering wobble under braking, and even hysteresis of the thrust arm. The bearing’s housing is precision machine from aluminum, to create a rigid part that allows for the M3’s thrust arm to move smoothly through its range of suspension travel. The improvement in steering and suspension feel is immediate and truly enhances the personality of the M3. *V2 improved design also incorporates hard coat clear anodized finish*

This is especially true for the E9x cars, as the original BMW camber eccentric bolt has an impact on toe as well. Alignments are made faster and simpler when using a set of aftermarket lower arms, enabling the alignment tech to easily reset toe after adjusting camber. The race toe link kit by Fall Line Motorsports is designed to facilitate rapid adjustments of toe during an alignment, and combined with the tension strut will also enable adjustment of overall track. Not only does this allow for fine tuning of wheel fitment, these arms will allow an alignment shop to make quick work of car setup, even simplifying the camber adjustment process as a result. The race toe links utilize a unique clamp-style fastener system as seen in BMW’s own tie rods and Porsche Motorsport components, tightening the adjustment arm in place with no stretch of the hardware or change of alignment. Less expensive jam-nut designs limit precision and nearly guarantee an alignment change when the jam-nut is tightened. Laser cut lockout washers correctly eliminate the original BMW adjustment, eliminating any unwanted movement in the system.
