BMW Control Arm Replacements & Upgrades

Stock rear lower control arms offer very little adjustment for alignment, especially in lowered vehicles, due to their use of an eccentric bolt. These aftermarket performance control arms from ECS Tuning are designed for maximum adjustability, allowing you to maximize handling and minimize tire wear.

To ensure maximum reliability, ECS Tuning's control arms are constructed from strong, lightweight 6061-T6 aluminum and feature a 303 stainless steel center turnbuckle that offers over 8 degrees of fast and precise camber adjustment. The inner bushing is a stock style serviceable OEM bushing for long life and inexpensive maintenance.

Features:

Durable construction suitable for the daily driver and track car alike
8+ degrees adjustment range for dialing in any suspension and wheel/tire setup
Center located adjuster for maximum clearance during adjustment
OEM-style bushing for long life and inexpensive service
Black anodized 6061-T6 aluminum with 303 stainless steel turnbuckle
Includes new hardware
*With the exception of the stance community, most enthusiasts will need no more than a few degrees of adjustment range. Total adjustment often is dependent on wheel/tire clearances.

The rear lower control arms on E82/E9X models are the weakest link in the rear suspension. The arm is made from folded sheetmetal and it bends and deforms easily. Not only will it deform from potholes and curbs, tow truck drivers love to hook onto them without realizing how weak they are. We have seen other race teams complete the box section to make them stronger. A bent arm will throw off the geometry in the suspension, potentially affecting handling and tire wear. These aluminum arms are both lighter and stronger than the factory sheetmetal arms and is the best solution for chronic bending of the stock arm. These are a direct replacement to your stock arms with no changes needed to your alignment. New high-grade hardware is included.

Note: the stock arm is designed from the factory to be intentionally weak. These arms will bend so that something else in the suspension does not break. Our race cars used the stock sheetmetal arm but we replaced them often. We found that it was better to finish a race with a bent arm than not finish due to a catastrophic failure. The ECS arms are still designed to be the weakest link but are far stronger than the factory arm and will not bend as easily.

• CAD plated grade 10.9 hardware
• Include washers and bolts for both sides of your vehicle.
• Made in the USA!

These upper A-arms are an adjustable version of the stock upper control arms. They feature an adjustable outer ball joint that changes the camber spec. These are great for dialing in up to half a degree of camber quickly and easily. An alignment pin conveniently sets it in the stock location. The inner bushing is a heavier-duty version of the stock rubber design. The stiffer rubber means less flex and deflection which helps in steering response and handling. Adjusting camber can help with handling and steering response. Adding negative camber is useful in spirited driving on secondary roads and even on/off ramps and can help with tire-fender clearance. This is a direct replacement for the original arm.

Replaces factory BMW part numbers 31126775967, 31126779871, and 31126779908.

The original factory bushings are fluid filled and rely on the fluid to absorb vibration and resist deflection. When the fluid is gone the rubber left over cannot match the original bushing's strength. The left over rubber is not stiff enough to resist the movements from the suspension. The result is a lot of vibration and reduced feedback and response from the steering. 

Meyle has addressed this issue with bushings that are not fluid-filled. The bushing is made of solid rubber that will last longer than the original bushing and is a bit stiffer than new originals for better response and feel. The lack of play from the solid rubber design will mean sharper steering, restoring much of the car's precision and 'connected' feel. 

This control arm comes with the Meyle HD bushings already pressed in. This makes for an easy swap out-swap in install. These arms replace the existing stock upper control arms - otherwise known as a tension strut or strut support arm. It's the arm with the twist. 

Meyle is a German brand in business since 1958 and all of their products are TUV approved and meet or exceed ISO standards. All Meyle HD parts come with a 4-year, unlimited mileage warranty.
