Turner Motorsport BMW Suspension Parts

Rubber mounts in any position of a vehicle are usually designed with comfort and longevity in mind leaving performance as a sacrifice. This kind of sacrifice here at Turner just won't do, so we did what we do best and designed a solid monoball mount.

Our engineering team first wanted to tackle the issue with wear found on rubber mounts. Due to their combination of steel, rubber, and low mounting location, these mounts are a direct target for deterioration and failure. As they are positioned out in the open and exposed to the elements, bonded steel and rubber components inevitably hold moisture, separating as the steel bearing begins to rust. Our solution was to offer a rebuildable mount with a Teflon lined bearing for increased durability, combined with a blue anodized body and melonite coated bushing sleeves for corrosion resistance.

The performance side of these mounts is primarily found in the articulation allowed by the bearing. Rubber mounts do not allow for proper free damper movement, hindering shock performance. By eliminating the deflection found in factory rubber mounts and allowing full shock articulation, this solid monoball design eliminates slop and maximizes shock efficiency and performance, allowing for more predictable handling on the street or the track - with almost zero added noise, vibration, and harshness.

One of the tricks for getting your BMW to handle better is to add negative camber to the front wheels. This will put more of the tire's width in contact with the ground during cornering. With more rubber there is more grip. BMWs typically have less camber in the front to create understeer. But if you're running a stock setup on the track or autocross you are giving up speed and time as the front tires run out of grip sooner than they should. 

Increasing the negative camber of your E36 M3 will reduce understeer and prolong the life of your tires when used on the track. These plates simply bolt on top of the factory upper strut bearings and increase negative camber by .5 or 2 degrees, depending on the holes you chose to use. We maximized the available camber available with a stock-diameter sized spring. Vehicle height in the front will be raised by .25”. We also added material to the surface area of the mount to increase stiffness of contact area, therefore reducing the strut tower deformation and increasing the strength of the strut towers. Fixed mount camber plates are legal for many racing and autocross classes. These are the perfect camber solution when adjustable plates are not allowed in your class.

3 way adjustable 30mm front sway bar / swaybar for E46 M3. Includes bushings.

• Reduces body roll
• Improves steering turn-in and handling

Sway bars are typically sold as a front and rear set to balance the handling. But a front sway bar only can also have excellent benefits, especially on a street car. Going with a larger front bar will improve steering and handling even at low-moderate speeds. Steering turn-in is faster and gives the car a more direct and responsive feel. Cars with staggered wheel fitments (a narrower front wheel compared to the rear) will especially benefit from this and help the front tire 'bite' into the road.

We use an adjustable 30mm sway bar that has been fine-tuned for use on the E46 M3. Urethane bushings with a reinforced inner core that requires no lubrication are included. These bars are crafted from a special spring steel that is both stronger and more resilient than competitive sway bars. They have been shot peened and heat treated, and feature precision forged ends.

2001-2006 E46 BMW M3

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.
