This E46 325Xi/330Xi front control arm is a direct replacement for the original part and is the OEM Lemforder brand. The E46 Xi front control is a special design borrowed from the E34 525Xi (sold in Europe) but still similar to other E46 cars. Therefore, it still suffers the same ball joint issues as the other 3-series models.

Control arms, and the associated 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.

On the Xi we also recommend replacing the inner ball joints and rear bushings when changing the control arms. The ball joints are designed to be replaced separately and the bushings are mounted at the back of the control arm. Both are high-wear parts and easily replaced with the control arm off the car.

To reduce the understeering affects of a staggered wheel setup you want a balanced set of sway bars. ECS has configured this anti-roll bar set for the non-M E46 with a 27mm adjustable front bar and a 21mm rear bar. The front is adjustable to two positions to fine-tune the handling and reduce understeer. The rear bar is fixed to retain the stock sway bar link. These anti-roll bars include urethane bushings with a reinforced inner liner that eliminates squeaks and doesn't require lubrication. The bars are powder coated for durability and good looks.

These bars fit in the stock locations using the existing brackets and links. Adjustable links are not required but recommended if the car is lowered or if you have coil overs (note: the rear bar is designed to only use the stock link, heavily lowered cars should not use this kit).

The bars are adjustable so any driver can find an ideal setup for the type of driving they are doing. The sway bar becomes stiffer in the hole(s) furthest from the end of the bar. The holes at the very end of the bar are the softest setting. We would generally recommend starting out with the front bar set to the stiffer setting and adjust to your liking from there.

BMW E46 Turner Motorsport Front Control Arm Performance Kit: Upgrade Your BMW's Handling

• Improves handling and steering response
• Enhances cornering stability and control
• Reduces flex and play in the front suspension
• Durable construction ensures long-lasting performance

Enhance the performance of your BMW with the BMW E46 Turner Motorsport Front Control Arm Performance Kit. This kit is designed to improve handling and steering response, providing a more dynamic driving experience. With enhanced cornering stability and control, you'll feel confident taking on corners and curves. The kit also reduces flex and play in the front suspension, resulting in improved overall handling characteristics. Plus, its durable construction ensures long-lasting performance, making it a reliable upgrade for BMW enthusiasts.

When you're looking for a control arm upgrade for your M3 this Turner Motorsport package is unrivaled, featuring their popular monoball bearing to replace the failure prone rubber bushing. The upgrades for this product aren't only that they will outlast everything else you can put on your car. These monoballs offer much smoother, more responsive steering that allows the front control arm to articulate more naturally instead of fighting against the suspension causing deflection.

Stock rubber front control arm bushings are designed to allow significant fore/aft movement of the front wheels to help absorb road impacts.  This soft flexible design maximizes daily driving comfort and helps to add the “luxury” feeling to your BMW, but it is far from ideal for the performance or racing enthusiast that is looking for optimal handling and braking performance.  Being a bonded rubber bushing that is constantly twisting and deflecting when in use, stock rubber bushings take a beating and often fail prematurely, resulting in further degraded handling, braking shimmy or even clunking felt under your feet.

In the past, the only upgrade option to improve handling of your E46 M3 was to replace the stock rubber with poly bushings, or delrin bushings that wear prematurely and are not serviceable or rebuild-able.  While well-designed poly bushings can vastly improve handling characteristics and offer good road feel with minimal increase to NVH, they are still a compromise when it comes to ultimate handling and braking performance.

Introducing the new Turner Front Control Arm Spherical Bearings!  The Turner engineering team set out to design a no-compromise solution that requires no modification and offers instantaneous cornering and braking response.  Our control arm bearings utilize a unique grease-able spherical bearing that is both serviceable and replaceable, with integrated dust seals to help keep dirt and moisture out.  This bearing offers considerable improvement in both precision and durability compared to other unsealed poly and delrin bushing inserts previously available, which can wear prematurely due to contamination.  The bearing assembly utilizes the highest quality materials, precision machining quality, and components to ensure a perfect fit and longest lasting component life possible.

The result is the ultimate in terms of low friction, no binding, and no unwanted deflection, as well as exceptional steering precision, turn-in response, and direct braking feedback with minimal increase in NVH.  These spherical bearings are a must have for any track car, but are also completely street-able and are a great upgrade for any enthusiast that enjoys spirited driving.

There's finally an option to buy housings separate from the bushings, this way you don't have to live with the stress placed on the stock housings when pressing the old bushing out. The biggest benefit come in when there isn't already a pre-pressed in option for poly and spherical upgrades, this leaves the only option of pressing the old bushings out. Through out in-house testing when designing our poly and spherical upgrades we noticed that pressing the bushing out caused stress in some cases creating hairline cracks in the housing leaving it vulnerable to failure.

Control arm bushings play a key role in connecting the wheels to the chassis of the vehicle. Tasked with keeping suspension geometry in check while absorbing noise, vibration, and harshness (NVH) factory rubber bushings were engineered to provide a balance of comfort and control. As a factory bushing ages, it becomes brittle and begins to harden. When this happens the bushing will actually shrink and allow excess play in the suspension joint. This is typically felt by a sudden jerk forward after the car comes to a stop and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushing with a full polyurethane unit or using a bushing insert, this play is eliminated since the suspension joint is being supported 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 inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.

Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This, in turn, reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.
