BMW Suspension Bushings & Mounts for BMW 2 Series F23 (2015+)

BMW’s are known to have failure prone front thrust 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. 

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 front 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).  We wanted to offer E31, E32, E34, E38, E39, E53, E60, E63, E64, and E83 owners similar levels of handling precision and control for the track and street. 

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.

Features:

Bearing housing

• Precision CNC machined from 6061-T6 blue anodized aluminum
• Knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands.
• CNC machined 304ss ball joint sleeve inserts, providing a precision fit between the ball joint and the subframe. 

Bearing

• OEM BMW sealed and greased ball joint for exceptional durability and service life.

Performance

• Nearly instantaneous, crisp steering and braking response.
• Maintenance free, long lasting performance. 
• Improved road feel without undesirable NVH.

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 separately here if you would prefer that option.

This item is an upgrade to the following rear wheel drive BMWs: 
2014+ F22 BMW 228i 230i M235i M240i - Coupe
2014+ F23 BMW 228i 230i M235i M240i - Convertible
2012+ F30 BMW 320i 328i 328d 335i 340i - Sedan 
2014+ F32 BMW 428i 435i 440i - Coupe 
2014+ F33 BMW 428i 435i 440i - Convertible 
2014+ F36 BMW 428i 435i 440i - Gran Coupe

Modern BMW's are beginning to leave the performance derived handling and power delivery in the past as the demand for more comfort and features rises. The stiff suspension components designed around having the best driving experience from a luxury car has been left for the M models and replaced with soft rubber bushings and mounts. Unfortunately, this is a good move by BMW to support the masses.

The obvious approach was to offer products so the modern BMW can be upgraded into the car the enthusiast desires, superb handling, control, and a direct delivery of power to the rear wheels. When you upgrade to our Delrin subframe mounts you reconnect that power with almost zero negative feedback.

The added appeal to someone looking to take one of these machines on the race track is Delrin can be used when solid mounts are needed and aluminum is not an option with strict regulations found in Grand-Am, BMW CCA, and other racing series.

Product features:

• Precision machined Delrin(TM) 150 bushings.
• Precision machined 6061-T6 aluminum inserts. 
• Class legal for any racing class that does not allow a solid subframe bushing. 

Performance Benefits:

• Eliminates subframe movement for more direct throttle and suspension  response. 
• Minimizes wheel hop due to subframe deflection and movement.

For someone looking for superior performance and longevity these sealed monoball bushings are the best upper thrust bearing you can buy for an F22 2-series or F3X 3/4-series. The advantage of a monoball bearing is that it will not deflect under load. All of the rubber bushings move in all sorts of directions and that changes your alignment, especially when used with big brake kits or when driven hard. The condition worsens as the bushing wears out. The Dinan monoball sits in a CNC machined aluminum housing which has zero deflection. The monoball allows complete freedom of movement but only at the desired angles. What you get is superior steering precision, better handling from more consistent alignment, and almost infinite bushing life. And thanks to the inner liner and sealed rubber boots there's none of the extra noise or reduced service life of fully solid race bushings. 

We strongly advise using these with new control arms. BMW recommends that the bushings be replaced only once per set of control arms. So if your thrust arm bushings have been replaced already then we do not recommend re-using the arms. The other reason is that the aluminum arms stretch over time which will make the bushings loose inside the arm. Other manufacturers recommend filling the stretched arms with paste but replacing the control arm is the better solution.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere.

Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) factory rubber subframe bushings were engineered to provide a balance of control while keeping the ride quality soft and supple. As a factory bushings age, they become brittle and begin to harden. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.
