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.

This left/driver's front upper control arm - also know as a tension strut or thrust arm. This is the control arm with the outer ball joint pointing down. This is the OE BMW replacement (made by TRW) and fits E82 1M Coupe and E90/E92/E93 M3. This control arm includes the inner pressed in bushing and outer ball joint. A direct replacement from the original manufacturer.

This part can also be used as an upgrade on non-M E82, E9X, and E89 Z4 models. The inner bushing on the M3 arm is a solid rubber instead of the fluid-filled non-M design. This solid rubber part will last longer and be more responsive thanks to less deflection in the bushing. The M3 arm is a direct replacement for the stock non-M part.

This item fits the following BMWs:
2006-2011 E90 BMW 325i 328i 330i 335d 335i M3 - Sedan

The M3 control arm upgrade is for people who want a very serious change in the ride/handling of the car. These are the factory OEM E9X M3 upper control arms, so the ride will not be much different than a standard M3. But it is a very large jump compared to the stock E9X arms and bushings, since they are not fluid-filled and have a harder rubber compound than the stock or Meyle HD bushings. These are direct replacements for the original arms, do not require any modification to install, and will add about .75 degrees of negative camber to the front for improved handling and tire wear

*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

These M3 rear guide rod arms are an upgrade for the non-M cars. The stock non-M arms are made from sheetmetal spot welded together at the ends. The arm tends to flex and bend under even moderate cornering loads. Factor in gripper tires and more torque and this arm is inadequate for stability and consistent handling. The M3 arms are one piece of aluminum offering greater strength and with a sealed monoball inner bushing that allows the arm to rotate (instead of twisting).

Over the years, the road takes a serious toll on your suspension. Potholes, speed bumps, and road hazards all contribute to a sloppy, weak suspension. To give a better feel to your driving experience and improve safety and ride comfort, replace suspension components as they wear. After years of service, non-serviceable ball joints and other components begin to wear out. Because some components cannot be replaced, the only solution is the replacement of the entire arm. This OEM TRW kit includes all four front control arms for the E9X M3 / E82 1M. Replacing all four at once will provide the most service life out of replacement parts and ensure they are all performing properly. This kit is intended for installation on Halogen headlight-equipped models, as a headlight level sensor rod is not included.

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.

Nearly every car manufactured in the modern era carries a dark secret – fully-adjustable suspension has been all but eliminated in the name of cost-cutting and assembly-line efficiency. What this means for you is increased tire wear and more frequent replacement, as a “full alignment” consists only of rudimentary toe-angle adjustment. For over forty years, K-MAC has been hard at work developing a solution to this problem with patented innovations in camber/caster plates and bushing kits, allowing easy adjustment and a true “full four-wheel alignment” to be performed by any competent shop. These bushings make camber adjustments possible for the first time, and improve the ability to complete toe angle adjustments. When used in conjunction with the K-MAC Camber and Toe kit and Rear Adjustable Trailing Arms allows full adjustability of the 5 multi-link rear arms and positive location. Bolt-on installation – insertion/extraction tube included! Easily adjusted on the car with basic hand tools Unique failsafe locking hardware – set & forget! High quality elastomer compound resists binding Hardened & nickel-chrome plated centers for maximum bushing life 2x the load area of stock bushings Spiral grease grooves

These upper wishbones boast two major benefits: replace the OEM rubber bushings with spherical units and add valuable adjustability versus the standard, fixed arm. The new adjustment capabilities allow ultra fine-tuning within the full-suspension suite—the more consistent suspension geometry, amongst other benefits, results in significantly improved performance and confidence in all driving conditions.

From years of competitive race experience, Fall-Line has become synonymous with producing not only championship caliber race cars, but the finest suspension components that help propel them to victory. As the final piece within Fall-Line’s suite of rear suspension offerings for the F8X M2 / M3 / M4, these upper wishbones boast two major benefits: replace the OEM rubber bushings with spherical units and add valuable adjustability versus the standard, fixed arm. The new adjustment capabilities allow ultra fine tuning within the full suspension suite—the more consistent suspension geometry, amongst other benefits, results in significantly improved performance and confidence in all driving conditions. These arms are direct replacements for BMW Part No. 33322284777. The F8X cars will notice an immediate difference due to its unique subframe and chassis relationship—torsional rigidity is further improved with the addition of these arms with only marginal increases in NVH. As an added benefit, the spherical bearings will outlast the OEM rubber variants, saving the headache of repeated replacement over your ownership. Product Details: Fits all F8X M2 / M3 / M4 Motorsport clamp-style fastener for faster, more reliable alignment adjustments Long-life FK spherical bearings Made in USA Replaces OEM BMW Part Numbers: 33-32-2-284-777

Fall Line’s mono ball spherical bearing conversion kit transforms the front steering and suspension feel of the M2. The factory rubber bushing is very large, and is prone to substantial deflection under load, as the M2 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 M2’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 M2.

One item to replace is the control arm. After years of service, the non-serviceable ball joints and other components can begin to wear out. Because some components cannot be replaced, the only solution is replacement of the entire arm.

This upper front control arm (BMW may call it a thrust arm or tension strut) comes with the inner bushings and is a direct replacement for the original part, made by Tier 1 supplier TRW.

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.

This arm includes the inner rubber bushing but the outer ball joint is sold separately.

This item fits the following BMWs:
2004-2010 E60 5 Series 525xi 528xi 530xi 535xi & xDrive models

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 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.
