BMW Control Arm Replacements & Upgrades for BMW Z Series G29 (2019+)

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.

BMW’s are known to have failure prone rear control arm bushings. The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change. This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience. Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure.

BMW's are notorious for their failure-prone control arm bushings. The pliable rubber bushings, present even in M performance models, allow substantial movement of the front wheels to enhance everyday driving comfort. However, they also permit significant alignment changes, leading to a disconnected and numb road feel that detracts from a confidence-inspiring driving encounter. Over time, the fluid-filled rubber bushings succumb to fatigue and cracking due to continual deflection and ozone degradation, ultimately resulting in the leakage of damping fluid and complete failure.

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available! Our experience with spherical 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).

The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise. We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting. The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment. What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.

Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set, and are available (T599476) if you would prefer that option.

Verkline's journey to develop an exceptional suspension set for the Supra A9X and BMW Z4 G29 began from day one, and it was significantly influenced by Robert from Apex Nürburgring YouTube video. With a profound understanding of high-speed driving dynamics, Verkline collaborated with Apex to craft a suspension set that pushes the boundaries of performance. Key Components in the Full Set: Rear Lightweight Tubular Subframe (WAS-401) Front Caster Adjustable Control Arms (WAS-410) Front Lower Adjustable Control Arms (WAS-411) Front Bump Steer Adjustable Tie Rod Ends (WAS-412) Front Sway Bar End Links (WAS-413) Rear Adjustable Traction Links (WAS-421) Rear Upper Adjustable Lateral Straight Links (WAS-422) Rear Upper Adjustable Lateral Bent Links (WAS-423) Rear Adjustable Toe Links with a lockout kit (WAS-424) Rear Spring Wishbone Bushings with lockout kit (WAS-425) Rear Knuckle Bushings (WAS-426) Rear Sway Bar End Links (WAS-427) Comprehensive installation and suspension setup instructions (66 printed pages) Toyota Supra A9X and BMW Z4 G29 were designed for an exhilarating driving experience on the streets, but their factory settings may not suffice for those seeking high-performance capabilities. The issue lies in rear-end bump steer, which affects the toe angle during suspension travel. The Consequences of Bump Steer: Rear toe changes unpredictably, impacting stability and handling. During hard acceleration, the rear end tilts, resulting in toe-in. Under hard braking, the rear suspension rises, leading to toe-out. Verkline's Solution: To address these issues and enhance performance, Verkline offers three suspension setup presets (Track, Street, Drag) tailored to various driving styles. These presets provide precise alignment, ride height suggestions, and arm lengths, ensuring optimal kinematics for every designated use of the car. Say goodbye to unpredictable handling issues and experience stable and controlled driving with Verkline's Suspension Set for Toyota Supra A9X and BMW Z4 G29. Transform your car's performance with the expertise of Verkline and Apex Nürburgring. Fits these models: Toyota Supra A90 Toyota Supra A91 BMW Z4 G29
