This left/driver's front upper control arm - also know as a tension strut or thrust arm. This is the control arm with the outer ball joint pointing down. This is the OE BMW replacement (made by TRW) and fits E82 1M Coupe and E90/E92/E93 M3. This control arm includes the inner pressed in bushing and outer ball joint. A direct replacement from the original manufacturer.

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.

This item fits the following BMWs:

The M3 control arm upgrade is for people who want a very serious change in the ride/handling of the car. These are the factory OEM E9X M3 upper control arms, so the ride will not be much different than a standard M3. But it is a very large jump compared to the stock E9X arms and bushings, since they are not fluid-filled and have a harder rubber compound than the stock or Meyle HD bushings. These are direct replacements for the original arms, do not require any modification to install, and will add about .75 degrees of negative camber to the front for improved handling and tire wear

These M3 rear guide rod arms are an upgrade for the non-M cars. The stock non-M arms are made from sheetmetal spot welded together at the ends. The arm tends to flex and bend under even moderate cornering loads. Factor in gripper tires and more torque and this arm is inadequate for stability and consistent handling. The M3 arms are one piece of aluminum offering greater strength and with a sealed monoball inner bushing that allows the arm to rotate (instead of twisting).

Over the years, the road takes a serious toll on your suspension. Potholes, speed bumps, and road hazards all contribute to a sloppy, weak suspension. To give a better feel to your driving experience and improve safety and ride comfort, replace suspension components as they wear. After years of service, non-serviceable ball joints and other components begin to wear out. Because some components cannot be replaced, the only solution is the replacement of the entire arm. This OEM TRW kit includes all four front control arms for the E9X M3 / E82 1M. Replacing all four at once will provide the most service life out of replacement parts and ensure they are all performing properly. This kit is intended for installation on Halogen headlight-equipped models, as a headlight level sensor rod is not included.

This upper front control arm (also known as a thrust arm or tension strut) is a direct replacement for the original part and is TRW 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.

This item fits the following BMWs:
2004+ E63 6 Series BMW 645ci 650i M6

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!)

Reinforces the strut towers against deformation while adding valuable triangulation to the front end for sharper, more predictable handling. Designed to prevent “mushrooming” and other distortion caused by rough roads or stiff suspension setups, these plates help maintain consistent suspension geometry by reducing unwanted chassis flex. The result? A more stable, confidence-inspiring front end under load. Strut tower plates are engineered to sit perfectly flush against the towers. If they don’t, it’s a sign the towers have experienced some deformation. In minor cases, this can often be corrected using a block of wood and a hammer to carefully restore the mounting surface.

Failed control arms commonly cause vibration and shaking that is transmitted through the steering wheel, increasing with speed or braking. Symptoms may also include suspension noises, incorrect steering alignment, and accelerated tire wear.

One item to replace is the control arm. After years of service, the non-serviceable ball joints and other components can begin to wear out. Because some components cannot be replaced, the only solution is replacement of the entire arm.

An integral part on E46 M3 is the rear chassis "V-Brace" (BMW # 33312229899) found on all 2001-06 Convertibles and Coupe (including the CSL). This brace attaches to the outward points of the rear chassis and to the area near the rear subframe carrier. Since some of these vehicles are now over 20 years old, we have been seeing more and more of these start to rust away. We began studying the OEM part, curious as to why they were starting to rust away. We found that the two arms of the "V" are made from 38mm x 12mm (1.5" x 0.5") hollow square steel tubing, pressed ends and welded to a junction plate joining them with welds holding the arms at a specific angle. Since the arms are hollow, it helps keep the overall weight down, but does little to prevent corrosion since it is difficult to paint/coat a hollow tube. A Google search turned up very little other than used ones on eBay and new ones that turned out to be in short supply from the BMW dealer (not surprising since the car is over 20 years old). Determined to make something better, we began our engineering and R&D process. Goals of our Design; Modular design, since packaging and shipping something this large would probably be too expensive Costs would dictate material and manufacturing methods Lighter weight would be a secondary (or tertiary) goal, but also keeping in mind costs Corrosion resistant, so it would not rust from the inside out, like the OEM version After weighing the material, manufacturing and cost options, we decided to go with a fully CNC'd ACQ 6061-T6 aluminum assembly. The concept is to machine two identical arms (one part number) and have them joined with a "junction plate". The arms would be secured to the plate with Grade 8.8 grade hardware and the entire assembly would include replacement Grade 10.9 hardware to replace the original OEM hardware (which is probably original). Details of our Design; CNC'd 6061-T6 construction, secured with Grade 8.8 socket head cap screws. Included are replacement Grade 10.9 hardware to fit in the factory locations. About 4 lbs. fully assembled weight (vs. 6.25 lbs for OEM), about a 35% weight savings Anodized gray finish Modular design allows for one arm to be removed in case of exhaust removal requirement. Included in the Kit Two (2) arms of the brace assembly (they are idential) One (1) junction plate One (1) red spacer (this goes BETWEEN the brace and the chassis!) Two (2) blue spacers (these goes BETWEEN the brace and the chassis!) Four (4), M10 socket head cap screws Three (3), M10 flanged hex head bolts It is recommended that the holes used to mount the V-brace onto the car be cleaned before installation by running an M10x1.5 tap to clean each of the holes.

Updated design!  Now shipping!

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 (and collars).

Stainless hardware and spacers are perfect for the tough Northeast climate!

New!  Easy adjustment with 22mm open ended wrench and 5mm allen key!  It only requires 15 ft. lbs. on the clamp to secure the clamp!

New!  Included lock-out kit, replaces factory eccentric hardware.

Updated 3-piece rod ends features 4130 chromoly steel bodies, heat-treated, alloy steel races, and Teflon liners

Extremely easy installation and adjustment (your alignment shop will LOVE you!)

As many may know, all springs are not created equal. Though they may carry similar diameters and spring rates, there is another factor many may not know. The manufacturing process and material play a crucial role in performance. Many years of experience, along with countless hours of research, Swift springs believes to have perfected the process. Putting this into action, Swift went to work with the goal of creating a new material. The culmination of hard work and determination, they created a proprietary steel alloy called "HS5.TW." This material accomplishes the primary goals Swift set out to accomplish which is as follows: The most consistent spring rate throughout the stroke The largest amount of stroke The highest durability against loss of spring height The lightest in weight Opening in 1997, Swift has dealt with a multitude of tasks and applications. From oval track and dirt racing, to the enthusiast street driver, Swift has gathered years of experience with world-class race teams and drivers around the world. With such a variety in demands over the years, you can rest assured knowing Swift will have the perfect spring to accomidate any need.
