BMW Suspension Parts for BMW 3 Series E46 (1999-2005)

The upper strut mount provides a locating point for the top of the front struts. It contains a rubber-isolated bearing that allows the strut shaft to move independently from the rest of the suspension - a critical component for the suspension to be quiet and effective. The rubber also absorbs vibrations and impact harshness, helping to keep unwanted noise and harshness from reaching the steering wheel.

Our sealed Monoball Rear Trailing Arm Bushings (RTAB) are the best solution for completely eliminating deflection and unwanted toe changes on the rear of the E36, E46, and Z4. While rubber and urethane bushings flex during load, the toe can change widely giving you nervous and unpredictable handling. These RTABs have a solid aluminum housing with a high-quality sealed OE bearing. These bushings were developed from years of competition use in various racing and HPDE events. There is simply no better RTAB unless your racing class rules prohibit the use of mono or spherical bearings.

The rear trailing arm bushings take a lot of abuse from acclerating, braking and cornering. The stock rubber bushings are just not up to the task of keeping rear wheel alignment in spec for very long, especially if you have upgraded to stickier tires and a better suspension. The pliable rubber flexes and twists which slows down reaction time and leaves you with a car that feels nervous and 'tail happy'. Urethane helps to control the alignment but issues with fitment, maintenance, and longevity keep us from recommending urethane on anything but a street car. We also offer a Delrin RTAB for cars that must conform to certain racing class rules. These sealed spherical bearings are the best at controlling rear toe alignment.

Our aluminum RTABs are very well made - high grade aluminum alloy and steel CNC'd out of a billet by an ISO 9001 certified manufacturer, each component is either hardcoated or nickel plated. While multiple manufacturers offer two piece designs, our research showed that a one piece bushing is a better design featuring a sealed bearing to keep contaminants out extending the life of the bearing.

These adjustable rear links are only required when using sway bar / swaybars with a suspension with a very low ride height, where it may be necessary to adjust the length of the end links for proper sway bar clearance from the drive axles or other suspension components. These suspensions are usually found only on race cars but this may also apply to street cars with sport springs/sport coil overs that are lowered a lot. On most street cars lowered 1.5" or less, the stock links will be fine.

These end links feature a Heim joint, which allows enough lateral movement when disconnected to adjust the length of the link without removing the entire link from the car. This is particularly helpful when eliminating or adjusting preload while tuning the suspension. Similar links without this joint, can't be adjusted without totally removing the link from the car.

Built-in grease fittings allow for occasional lube, and a packet of grease is included. These links are sold as a set, and include two end links and hardware for H&R and TMS sway bars (other brands may not need the hardware). 

At their shortest setting they are 2.875" hole to hole and on their longest setting they are 3.5" hole to hole.

*Note: these links will not work with factory or non-adjustable Eibach sway bars.

This is the stock rear swaybar link for the E46 3-series, except the M3 model. The link connects the sway bar to the suspension of the car and is under constant stress and motion. The rubber ends of the link will eventually wear out. When that happens the sway bar itself will move within the link and create a clunk noise. Swaybar links are one of the first places to check if you hear a clunk in your E46.

These camber plates are perfect for the enthusiast owner who wants a high quality design with a motorsports background. Knowing a full race kit on the street is not often the best option, we took the best features from the Race Camber Plates and incorporated them into a fresh Street design -

• preserves the correct E46 M3 geometry
• separate sliding camber and caster adjustments
• maximum shock travel
• light weight
• durable materials
• large surface area
• ease of use

The Turner E46 M3 Street Camber Plates are the most advanced design on the market. These are designed specifically for the E46 M3 - no shortcuts or cookie-cutter components. We started with a fresh design to make these very user friendly and easy to install and set up. The E46 M3 front suspension has unique geometry and the strut is mounted at an angle that can put significant side loading on the strut shaft if it's not located properly. The location and angles for the main bearing were carefully engineered to allow the proper motion ratio and strut angles during adjustment. This greatly reduces bending forces on the strut itself which improves performance and longevity. By designing for one chassis we're able to focus on what works best in that application - proper fitment and operation without unnecessary adapters, easy-to-use camber and caster adjustments, and an intelligent modular design.

For street use we added a pliable urethane bushing to absorb vibration and a special base design that works with the factory radial bearing and spring perch. The radial bearing allows the spring to rotate instead of twisting and binding. By re-using the factory radial bearing we can keep the assembled stack height lower for maximized shock travel. It's also a commonly-available item that you can get from any BMW dealer at a low price. All of the things that make it work well in the factory application carry over to our design. You can use our camber plates with a stock sized spring, 60mm, or 2.5" springs. Use your stock spring perch/bearing with stock-sized springs. The 60mm and 2.5" upper spring perches are sold separately. The beauty of our design is that you can use the factory radial bearing with any of these springs.

Another important feature of the Turner Camber Plates is the size of the upper plate. Our plates have a very large surface area to better spread strut forces through the strut tower. A smaller upper plate, like those found on competitor's kits, will localize strut forces and contribute to strut tower deformation ('strut tower mushrooming'). This is a very important feature especially as these cars get older and spend more time on the track. Deformed strut towers are a serious performance and safety concern and our camber plates are properly designed to handle the loads. The factory strut reinforcement plates are not required with our camber plates (but you can use them if you want to).

Since this design is specific to the E46 M3, we can build it with the bare minimum of adapters and extra hardware. This not only cuts down on confusion but makes it easier to assemble and operate. We use the correct-sized bearing for the 16mm strut shaft; no sleeves or bearing adapters required. The original tapered lower mount support and a small stainless steel spacer from our kit are all that's required to install. We have used our camber plates with most of the major strut manufacturers on the market - stock Sachs/Boge, Bilstein, Koni, H&R, ST, and KW. Our camber plates work with any strut that is designed to accept the factory strut mount.

E36/E46/Z4, including M models, rear lower control arm (camber arm, wishbone). This is a direct replacement for the stock arm and includes the inner bushing. These arms are designed to be slightly weak and flimsy as they will absorb impact energy. It's better for this arm to absorb an impact rather than the wheel or trailing arm, or subframe, etc. Also, unknowing tow truck drivers like to use this part to hook their chains on to. Consequently they bend as easily as a coat hanger. An OEM replacement from Lemförder is the perfect option to restore control and suspension quality.

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.

These E46 fixed camber plates are designed from knowledge gained from our highly successful racing campaigns with the E46 in the Speed World Challenge series. These plates are offset for the best camber and caster combination for racing purposes when using the stock-diameter sized springs. Camber increases to between -2.5° to -3.0°, depending on each individual car. While ride height is increased by 1/4", the benefit of these plates far outweighs the minor ride height increase. The rate of camber change is virtually unaffected throughout the range of suspension travel, reducing the need for other geometry correction. Material has also been added to increase surface contact area therefore reducing the strut tower deformation and increasing the strength of the strut towers. Fixed mount camber plates are legal in many racing and autocross classes. These are the perfect camber solution when adjustable plates are not allowed in your class. These are a simple bolt on part for all E46 except the xi and M3 models.

The E36/E46 rear trailing arm bushings (RTABs) wear out faster than any other bushing on the car. Worn RTAB will cause excessive toe alignment change and give a 'loose' or 'floaty' feeling in the rear handling. One of the reasons for this is that they over-extend during motion, stretching and twisting the rubber in all directions. These shims sit on either side of the bushing and limit the amount of extension from the bushing. Not only will you get more life from your RTAB but these will help stiffen the bushing during cornering. But during normal driving you will still have all of the comfort of the stock rubber bushings. These part about these bushings is how easy they are to install - simply slide them in place during your bushing install. They can be added to pre-installed bushings too by dropping the trailing arm and removing the cage around the bushing.

Works with stock rubber bushings only (not urethane or Delrin).

The front control arm bushings are a key piece of the suspension. They are constantly in motion and take abuse from impacts, potholes, rough roads, and general cornering/wheel motions. To give a quiet and smooth ride, the bushings are made of rubber with a metal sleeve insert. But the rubber can only withstand so much abuse before they become loose and spongy. This results in vibrations and possibly a shimmy when driving. A visual inspection will usually confirm that there is too much flex in the rubber or the rubber has cracked and torn. And if you're installing new control arms, always install new bushings to avoid duplicating labor costs.

This is a replacement stock LEFT FRONT (Driver's side) control arm bushing with the mounting bracket.

This E36 or Z3 front control arm is a direct replacement for the original part and is the OEM Lemforder brand.

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. 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. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.

We also recommend replacing the bushings when changing the control arms. The bushings are mounted at the back of the control arm and located the arm to the frame rail on the car. The stock bushings are rubber and will wear out sooner than the control arms themselves. With the control arm off the car now is the perfect time to also replace the bushings.
