Turner Motorsport 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 stock Genuine BMW rear toe links (33326792533) are great for standard daily driving and occasional spirited driving, but they tend to fall flat on the track due to the soft rubber bushings causing excess deflection, creating undesirable handling characteristics, not to mention insufficient adjustability. Turner's new Performance Rear Toe Links increase stability and response by eliminating bushing deflection while providing an increased range of rear toe adjustment, necessary for lowered cars or for performance alignments. Even small changes to ride height and camber will effect toe settings, and the wide range of adjustment allows you to maximize grip on a track car and extend tire life on a street car. The factory rear toe arms utilize an eccentric bolt and washer for adjustment and lack precision and range. These toe links feature gun drilled 2024 Aluminum center links, clamps, and clevises, along with a 360-degree rotating clamp system. This combination provides superior strength, performance, durability, and ease of adjustment. No annoying jam nuts! A simple 3/16" Allen-key is all that is required to lock down your alignment settings. FK Spherical Rod Ends are utilized to reduce alignment change in the rear suspension under hard cornering, acceleration, and braking. They feature a Teflon liner to provide quiet operation, low friction, smooth articulation, and eliminate bushing deflection under load. The PTFE liner is chemically bonded to the inner diameter of the race, offering a very high load carrying capacity and greatly increased dynamic wear characteristics. Rear Toe Links Features: Gun drilled 2024 Aluminum Links to reduce unsprung weight 6061-T6 Aluminum Rotating Clamp design Low friction 3-piece Teflon lined FK Heim joints/Rod Ends Sold as a pair Made in the USA

Rear Suspension Mounts With No Flex or Deflection for Improved Handling, Response, and Long Life
Building a track-only or racecar means swapping out the flexible rubber bushings and mounts for non-distorting solid pieces. The stock rubber bushings have serious drawbacks when used hard on the racetrack - they wear out quickly, and the flexible material allows extreme changes in alignment. Switching to solid bushings will eliminate the deflection and flex, keeping the suspension motions in their intended alignment and providing more feedback to the driver. On the E36, solid bushings can help prevent rear subframe failure as the sheetmetal chassis will no longer flex along with the rubber mount. Depending on the bushing's intended purpose, the material we use is either aluminum or Delrin. Delrin is a dense plastic material that has almost zero deflection and long life. It's self-lubricating so it won't ever need grease or lube. All of our bushings are designed by our in-house R&D engineers and tested on our various racing cars, with many used in professional racing series around the world.

If you're building a car for a racing class, the parts and materials you can change to are specified in the rules. Consult your rulebook or tech steward for any clarification. As these bushings have no play or deflection in them, they are not intended for street-focused cars - they do not absorb impacts and vibration like rubber will.

We offer bushings for the following suspension points -
subframe mounts x 4 (aluminum)
inner-upper control arm bushings x 2 (aluminum with bearing)
differential mounts x 3 (1 Delrin, 2 aluminum)
outer upper/lower control arm bushings x 4 (OE-spec replacements) (steel with bearing)
trailing arm bushings (RTABs) x 2 (aluminum with bearing or Delrin)
suggested: front control arm bushings (FCABs) (Delrin)
suggested: rear shock mounts (RSMs) x 2 (aluminum with bearing)

Notes
Note 1: there is also a inner-lower camber arm bushing. We never developed a solid bushing for this point because every racing class allows adjustable camber arms to be used in this location and we offer those with solid inner bushings.
Note 2: some racing classes require a non-bearing bushing for the rear trailing arm bushings. In cases like this, we use a Delrin bushing.
Note 3: the outer upper and lower bushings are already a monoball-style bearing from the factory on all M3 models. They are a great design and last a long time. We offer them as direct replacements or as upgrades for the non-M3 models.

Not only does our Roll Center Correction Race Kit correct your roll center and improve handling, but it also provides increased steering response and bump steer correction. Thanks to the use of our rack limiters, you can maintain the same steering angle as before, while drastically decreasing steering wheel input. After the kit was installed on our E36 M3 test vehicle equipped with a Z3 2.7 turn lock to lock steering rack, it only required 2 full turns lock to lock. A reduction of 26%! Bump steer is also correctable to virtually 0, thanks to spacers to adjust tie rods up or down. When you lower a car, it drastically changes the geometry of the suspension. While lowering a car makes it handle better by lowering the center of gravity, the roll center is negatively impacted, increasing the roll moment, which causes cornering forces to have more of an effect on the body roll of the vehicle. This is normally ignored because the stiffer lowering springs make the issue less noticeable, but ultimately grip is lost, and body roll is increased. Once the roll center has been corrected it is immediately apparent how much the performance of the vehicle had been suffering prior. By correcting the outer ball joint location with our Roll Center Correction Race Kit, the instantaneous center of rotation is raised, bringing the roll center much closer to the center of gravity, and significantly decreasing roll movement. This minimizes body roll, provides more grip, and ultimately leads to an improved and predictable driving feel. Roll Center can be a rather complex concept. Let’s break it down: On a McPherson front suspension vehicle, both the top of the strut and lower control arm sit at an angle. If you were to draw 2 lines, one from the upper strut mount perpendicular to the steering axis (line through lower ball joint and upper strut mount pivot) and another from the control arm outer and inner ball joint/pivot, Where they intersect is called the instantaneous center of rotation. This is the point about which the suspension is rotating at that instant. Now, noting the vertical center of the car, draw another line from the bottom of the center of the tire contact patch, to the instantaneous center of rotation. Where this line intersects with the vertical center of the car is where your “roll center” is. The distance between the roll center, and the center of gravity is called the “roll moment”. The larger the distance, the larger the body roll. By decreasing the distance between your center of gravity and your roll center, you can decrease the amount of body roll, and decrease suspension geometry change, and ultimately gain better handling. Features: 6061-T6 billet aluminum steering plate All specially designed, melonite coated, class 10.9 hardware Provides roll center correction for lowered cars (coilovers recommended, lowering springs and replacement shocks generally provide too much droop) Provides bump steer correction and adjustment Includes ball joint replacements (e36M 027427TMS01~A, E36/46 NM 022961TMS01~A) Kitted with high-quality FK rod ends

The performance of the front suspension depends almost entirely on this one bushing. The BMW front control arm mounts to the chassis with this bushing at the back. If the original rubber has worn it will have a major impact on the alignment, steering, and braking. This is why race teams like ours ditch the factory rubber and put something more solid in its place. The car will be more responsive due to less deflection and the bushing will last longer (virtually no wear). These Delrin bushings use an aluminum sleeve and are nearly solid to conform to many racing series rules, including SpecE46 and the Grand Am Cup series that we won back-to-back championships in.

These bushings require the 60mm bushing brackets (housings) from the E46 M3 or very early E46 models.

Factory bushings are more than adequate for street driving on the E46 M3. However, once the miles start to pile up, the bushings are meant to be replaced. Common side effects of worn factory FCABs include, but are not limited to the following:

Steering wheel shutter when brakes are applied
Wheel (and steering wheel) shimmy
Mysterious and irregular tire wear
"Overboosted" steering feel (very light steering)

Replacing with new factory bushings will return the factory feel. These urethane core bushings, however, offer something MORE. These bushings are designed to deliver performance that surpasses the stock E46 M3 bushing, while still allowing them to be used in everyday driving scenarios on public roads.

With the numerous delrin/urethane/hybrid replacement bushings in the market, we wanted to offer bushings that were not only effective, but simple. No clips, no washers, no multiple sleeves, and no "race parts in street cars". They have an aluminum outer sleeve with a replaceable, compliant urethane core that is serviceable and rebuildable. These urethane inserts prevent unwanted control arm deflection, while allowing noise/vibration/harshness (NVH) isolation -- a must on any bushing being used on a street driven car. And because of their compliance they remain very comfortable for daily use. But because they are a heavier-duty design than stock, these eliminate steering shimmy and wander, especially with the addition of big brake upgrades. They maintain BMW's original suspension geometry, and give your M3 a directly "connected" feeling with the front end of the vehicle. Perhaps best of all, these bushings are easy to install and are designed for longevity. Professional installation on suspension components is always recommended.
