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.

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!)

These BMW Motorsport Group N Bushings replace all of the bushings on the factory toe control arm (also known as the track strut). These inner and outer bushings feature a heavy duty rubber that is stiffer than stock. The stiffer bushing reduces deflection and twist in the arm, leading to more stable handling and faster response in the suspension. These bushings are great for track use and legal for some racing classes yet can also be used on a street driven car where extra ride harshness can be tolerated.

Sold as a set of 4 - two bushings for each toe arm.

Rubber has no place on a race car (except for tires, of course). Rubber suspension bushings are one of the first things to get swapped out for our race cars. The more solid the better when it comes to controlling the alignment and keeping your race setup consistent. We use as much solid material as the rules allow. With no deflection, solid bushings also give amazing feedback to the driver. For the M235iR, BMW had two specs for the rear control arms - stock stamped steel control arms with a rubber/neoprene bushing that is slightly stiffer than stock (2014-2015 spec) and these aluminum/stainless steel control arms with solid Heim-jointed ends (2016 spec). An additional benefit to the Heim joints is the arms are adjustable so the alignment can be perfectly dialed in. The front control arms use M3/M4 thrust arms and wishbones with sealed monoball joints. Full solid mounts and bushings will give you many setup options with razor sharp steering and chassis response. Note: 2016-spec rear control arms do not have a spring perch like the factory arms. These are for rear coil over shocks only.
