Turner Motorsport BMW Control Arm Replacements & Upgrades for BMW G82 M4 S58 3.0L

Clear BMW chassis

Please ensure your correct model is selected

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 trailing arms (33322284534) 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 Traction Links increase stability and response by eliminating bushing deflection under hard acceleration and braking and help to reduce wheel hop on hard launches. Thanks to their adjustable design, these allow fine tuning of rear bumpsteer and anti-squat characteristics. These arms are designed for use in high-performance street and race vehicles. These traction 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 Traction 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

The stock Genuine BMW rear toe links (33322284534) 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. Best if tightened to 73.7 ft. lbs. (100 N/M). DO NOT OVERTORQUE! ECS is not liable for any issues due to overtorque. FK Spherical Rod Ends are utilized to reduce alignment change in the rear suspension under hard cornering, acceleration, and braking.

The stock Genuine BMW front "upper" control arms (31108095667 & 31108095668) are great for standard daily driving and occasional spirited driving, but tend to fall flat on the track due to the soft rubber bushings causing excess deflection, creating undesirable handling characteristics. In order to address this issue, Turner now offers new Performance Front Tension Rods with upgraded FK Spherical Bearings! These tension rods offer multiple benefits over stock control arms, helping to keep your BMW under control and on the track. The biggest upgrade over the stock control arm is the replacement of the rubber bushing with JMX hardened Teflon-lined low-friction FK Spherical Bearings. This allows for smooth control arm articulation, without the standard mushy feel you'd expect from rubber bushings. As a result, you get a more responsive feel that inspires confidence lap after lap! The PTFE liner is chemically bonded to the inner diameter of the race. The liner offers a very high load carrying capacity and has greatly increased dynamic wear characteristics, offering robust reliability for both street and track use. Another benefit of these Performance Tension Rods is increased caster adjustment, allowing precise alignment for optimal turn-in response and to compensate for variances between left and right caster. Adjustable Tension Rod Features: Gun drilled and Blue Anodized 2024 Aluminum links to reduce unsprung weight Rotating 6061-T6 Aluminum Clamp design Hardened JMX high misalignment low friction 3-piece Teflon lined FK Heim joints/rod ends Stainless steel anti-dive spacers ASTM A574 socket head cap bolts are used for maximum articulation with a minimum tensile strength of 170,000 psi Sold as a pair. Made in the USA.

The stock Genuine BMW front "lower" control arms (31108095665 & 31108095666) 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. In order to address this issue, Turner now offers new Performance Adjustable Front Lower Control Arms! These control arms offer multiple benefits over stock control arms, helping to keep your BMW under control and on the track. In order to get the most out of your BMW M3/M4, these new control arms provide roll center, camber, and track width adjustment to dial in your alignment for optimal handling!
