BMW Suspension Parts

Whether you need a camber change or you are looking for more adjustment with your camber plates, you can change your camber by shimming the strut and spindle with the TMS bolt kit. There are some things to take into account with this kit so please read the installation tips below. An alignment is strongly recommended after installing this kit.

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.

Enhance rear-end control and put more power to the ground with a straightforward 3-piece design that installs with ease. The factory rubber may favor ride comfort, but it struggles to keep up when driving gets aggressive. As it wears, the OEM bushing can soften and deform, reducing stability and allowing wheel hop to creep in when you need traction most.

Our 95A durometer polyurethane bushings solve that problem. Engineered to strike the perfect balance between soft factory rubber and harsh solid mounts, they significantly reduce differential movement without introducing excessive vibration. The result is more efficient power transfer, so your torque goes straight to the rear wheels instead of being lost in drivetrain flex.

Features & Benefits:

Minimizes differential movement and instability to help eliminate wheel hop
Two-piece 95A split polyurethane design for easier installation
Precision-fit insert reinforces the bushing and strengthens mounting points
Resistant to road salt, oils, and harsh chemicals
Compatible with dual mount differential plates
Design:

Type II Anodized 6061-T6 CNC billet aluminum inserts for superior corrosion resistance and durability.
95A Polyurethane 2-Piece Isolator.
Product Development:

Our Rear Differential Bushings are designed, engineered, tested, and quality inspected by our Research & Development team. Our development process includes leading-edge product technology: FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

BMW G8X M3 M4 Rear Upper Arms are essential for maintaining optimal rear camber and minimizing tire wear for both street and track driving. The stock BMW setup can lead to excessive negative camber, especially noticeable in lowered vehicles, resulting in premature tire wear and reduced traction. These adjustable Rear Upper Arms provide a broad range of adjustment for precise rear camber alignment, crucial for both performance and longevity.
