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.

An underrated component of a proper driver's suspension the monoball kit (tension strut ball joint kit in today's terminology), is a remnant of an era when road feel was something desirable and sought after. Drivers wanted the visceral feel of being connected to the road as the road-racing heritage of BMW M demanded. Dinan embraced this and over the years mastered its craft into a kit that not only satisfied the desire for proper road feel but also made it livable for everyday driving. While stock suspension properties may have swayed from its golden era lineage to more mainstream ideals, Dinan is here to correct those mistakes for those that want a more M-passioned BMW experience. The Dinan Tension Strut Ball Joint Kit provides responsiveness you can feel by replacing the rubber bushings in the thrust arms with precision ball joints and machined aluminum housings. Improves responsiveness by eliminating the deflection inherent in the stock rubber bushings while also reducing brake shimmy. The quietest bearings on the market are virtually noise-free so you can live with them every day. These are the only bearings on the market that are sealed using a rubber boot to keep out dirt and road grime stopping them from wearing out prematurely. Features: Improved steering responsiveness. Reduces brake shimmy. Nylon-lined bearings for quiet operation. Machined aluminum housings. Sealed bearings.

Dinan's Rear Toe Links add precision and predictability at the limit.

The stock rear toe links are built with rubber bushings and a curved forged alloy rod. This design allows the rear wheels to have excessive toe change under hard acceleration and braking. All of this flex in the stock toe links causes the car to be unstable. Dinan stops the flex by replacing the rubber bushings with Teflon coated machined steel rod ends and the OEM curved bar with straight billet aluminum rods, thus adding stability. The Dinan rear toe link also incorporates a hex nut shaped center to aid in the necessary fine adjustment of the toe link that is tough to achieve using the stock link.

Features:

Replaces the stock rear toe link & rubber bushings with precision machine black-anodized aluminum rods and racing-quality rod ends

Dramatically improves vehicle stability during hard cornering

Improves response by eliminating the deflection of the rubber bushings

Rod-ends are Teflon-lined for quiet operation

Rod-ends incorporate left and right hand thread, which allows quick and accurate toe adjustment by simply turning center turnbuckle eliminating the need to struggle with the factory eccentric adjustment

Rubber boots protect rod ends from environmental damage for long lasting performance and removes the need for constant cleaning
