BMW Control Arm Replacements & Upgrades

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. They do more than just keep the alignment in a constant spec - they are a vital locating component for the suspension itself. 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.

Most control arms for BMWs consist of an inner and outer ball joint made of plastic, rubber, Delrin, or metal and covered in grease with a rubber boot to seal it from the outside. The ball joint rotates and spins as the control arm goes through its movements and that will wear the ball joint and make it loose. The grease inside the housing can also get used up, evaporate, or become contaminated from moisture and foreign particles. As the ball joint becomes worn it can result in excess movement within the housing. Your steering and handling will become less precise and there is usually a light clunking or clicking sound. In rare and extreme cases the ball joint can separate from the control arm completely, leading to a total loss of suspension and steering control. You should have the ball joint play checked annually and replace them every 3-4 years. Most track organizations will not allow a car if they are older than three years.

Control arms also take abuse from impacts and handling forces. Aluminum control arms will generally bend and prevent an accurate alignment. Steel control arms will crack and fracture and require close inspection annually and replacement every 3-4 years.

We sell OE BMW, OEM, and performance upgrade control arms from proven manufacturers. The control arm is so important to a BMW suspension that we insist on only top quality brands and designs and will never sell a control arm based on price alone. We also have upgrade packages with superior designs and better bushing options and we have bundled these together with valuable package savings.

This is the front upper right control arm with the outer ball joint pointing down. This replacement fits E82 1M Coupe and E90/E92/E93 M3 models. This control arm includes the inner, pressed-in bushing and outer ball joint. This part can also be used as an upgrade on non-M E82, E9X, and E89 Z4 models. The inner bushing on the M3 arm is a solid rubber instead of the fluid-filled non-M design. This solid rubber part will last longer and be more responsive thanks to less deflection in the bushing. The M3 arm is a direct replacement for the stock non-M part.

When an E9X is lowered beyond the limits of just lowering springs, the rear wheels toe-in excessively. This excessive rear toe leads to premature wear, that many people attribute to an increase in negative camber. It has become a common belief that an extremely low vehicle will wear the tires wrong as a matter of consequence. It has become standard practice to go as low as you can and proceed to replace your tires every five to ten thousand miles. Whats more is that when the vehicle reaches a certain ride height, the factory arms become maxed out and there is no way to compensate and dial in the proper toe. You're left with an improperly aligned vehicle that is in effect worse off than it was with the stock suspension installed.

This is not only uneconomical but improper and unsafe. ECS Tuning is proud to offer a solution for this problem in the form of Rogue Engineering E9X adjustable rear toe arms. These arms allow for greater toe adjustment on vehicles that have been lowered with a coilover suspension. With the toe set properly the tires can contact the road properly this maximizes grip and minimizes wear. 

Features:

  • 100% machined and anodized, 6061-T6 lightweight aluminum arms
  • High-strength, 3-piece, rod end (with carbon fiber reinforced, PTFE race) offers longer life for street compared to standard rod ends
  • SEALS-IT Rod end seals keep dirt, water, and other contaminants out
  • Rod ends feature grease fittings, to allow for rod end serviceability.
  • Lighter than stock!  (Stock is 875g, RE arms are 640g)
  • Extremely easy installation and adjustment (your alignment shop will LOVE you!)

Elevate your BMW's handling dynamics without sacrificing the refined ride quality you enjoy every day. This upgrade kit utilizes the front control arms originally engineered for the E90 M3 and E82 1M, providing a sophisticated enhancement to your suspension geometry and overall steering precision. While many aftermarket performance options rely on harsh polyurethane or noisy heim-joint bushings that trade comfort for track-focused rigidity, these M3 components offer the ideal middle ground for a spirited daily driver. Unlike the factory Non-M control arms that utilize fluid-filled bushings prone to cracking and leaking over time, these high-performance replacements feature solid rubber bushings. This design significantly reduces control arm deflection and sharpens front-end feedback, ensuring your vehicle feels more planted and responsive during cornering. Sidem has refined this setup even further by reinforcing key areas of the original factory design, resulting in a more durable and reliable component that stands up to the rigors of the road while maintaining a smooth, factory-plus feel.
