Upgrade your BMW's suspension with ECS Tuning Adjustable Sway Bar End Links, designed to provide up to 60mm (2.36") of adjustability. These end links allow you to eliminate sway bar preload or fine-tune it for specific racing needs and corner balancing. When installed, they improve drivetrain clearance and enhance sway bar responsiveness by reducing deflection, ensuring superior handling. Perfect for lowered vehicles using springs, coilovers, or air-ride suspension systems, these adjustable sway bar end links allow you to remove unwanted preload caused by changes in the center-to-center distance between sway bar mounting points. By adjusting the end links to a neutral position, you eliminate sway bar preload, enhancing suspension performance in various driving conditions.

The main body of the ECS Sway Bar End Links is crafted from strong, lightweight 6061-T6 billet aluminum and anodized red for superior corrosion resistance. Featuring left and right-hand threaded center sections and machined hex wrench fittings, these end links allow for quick and easy on-the-car adjustments. Zinc-plated hardware ensures secure and lasting adjustments, while the heavy-duty ball joint ends come with weather-resistant rubber boots and stainless steel wire retainers, providing superior protection against salt, rain, and ozone for extended durability. Each kit also includes zinc-plated Nyloc nuts and hardened steel washers for secure installation and improved contact surface on the sway bar.

Our sealed Monoball Rear Trailing Arm Bushings (RTAB) are the best solution for completely eliminating deflection and unwanted toe changes on the rear of the E36, E46, and Z4. While rubber and urethane bushings flex during load, the toe can change widely giving you nervous and unpredictable handling. These RTABs have a solid aluminum housing with a high-quality sealed OE bearing. These bushings were developed from years of competition use in various racing and HPDE events. There is simply no better RTAB unless your racing class rules prohibit the use of mono or spherical bearings.

The rear trailing arm bushings take a lot of abuse from acclerating, braking and cornering. The stock rubber bushings are just not up to the task of keeping rear wheel alignment in spec for very long, especially if you have upgraded to stickier tires and a better suspension. The pliable rubber flexes and twists which slows down reaction time and leaves you with a car that feels nervous and 'tail happy'. Urethane helps to control the alignment but issues with fitment, maintenance, and longevity keep us from recommending urethane on anything but a street car. We also offer a Delrin RTAB for cars that must conform to certain racing class rules. These sealed spherical bearings are the best at controlling rear toe alignment.

Our aluminum RTABs are very well made - high grade aluminum alloy and steel CNC'd out of a billet by an ISO 9001 certified manufacturer, each component is either hardcoated or nickel plated. While multiple manufacturers offer two piece designs, our research showed that a one piece bushing is a better design featuring a sealed bearing to keep contaminants out extending the life of the bearing.

Features:

Key Benefits:

  • Rear Trailing Arm Monoball eliminates unwanted deflection, maintaining alignment settings and minimizing wheel hop.
  • Allows full rear trailing arm articulation for low friction movement and eliminates binding found in rubber and poly bushings.
  • Completely streetable: utilizes an OES Lemforder brand sealed, greased ball joint for an extremely long service life with no increase to NVH.

 

Design Features:

  • Housing: Billet CNC 6061-T6 aluminum, type II anodized for exceptional durability and corrosion resistance
  • Bearing: OE Mercedes/lemforder 2043520027 Sealed ball joint
  • Bearing inserts: CNC machined 303 stainless steel.
  • Rebuildable

Made in the USA TMS rear subframe bearings are designed to limit rear control arm movement relative to the subframe. The stock BMW subframe bushings are made out of rubber, which allows variance in suspension position due to deformation and compression. A race car needs to have all suspension points remain in place for proper setup. By using high grade aircraft aluminum alloy and high performance race bearings, the TMS bushing replacements are both lightweight and strong. The casing is designed so that if maximum motion occurs, the load will be evenly distributed throughout the casing. Our flanges are designed to spread the load on the subframe and limit movement. The bearing we use is an extra wide race bearing to distribute the load over a broader area. Each piece is anodized or nickel plated to withstand corrosion. These bushings are a perfect compliment to the TMS lower camber arms.

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.

A very common weak point on the 3 series BMW is the sheetmetal of the rear shock tower. The sheetmetal here is relatively thin and very susceptible to stress and fatigue. A worn out shock will bottom-out more often and this energy is transferred through the bump stop and into the metal chassis. Stiffer shocks and shock mounts also put more stress on the sheetmetal. Factor in age, mileage, and environmental conditions and it's not a surprise that we see shock tower failures often. BMW addressed this issue with reinforcements of their own but our's are thicker for additional strength. This kit mounts on top of the shock tower and can either be bolted or welded in place. Because of the shape of the rear shock tower, these do not fit cabrio/convertible cars.

Worn rubber differential mounts will lead to the differential twisting and shifting around in the rear subframe. Not only will this be noisy but it's bad for driver confidence and bad for the chassis as well. Even on fresh rubber bushings the differential has deflection and twist, especially if the car has been modified for more torque. Since the differential is centrally mounted in the rear subframe, with all suspension mounts interconnected, a differential with too much deflection will affect handling and could even damage the rear subframe.

These 88A urethane E46 M3 diff mounts are much stiffer than stock but still not as solid as our Turner aluminum/Delrin bushings. This set will resist twisting much better than the stock rubber mounts. Included is the front diff mount and two rear mounts in the cover.

Our renowned TMS adjustable front sway bar / swaybar links for BMWs are now available in custom lengths, making them easy to order for any aftermarket or custom suspension setups. Simply measure for your ideal link length, and order the links with the best length range (below). Each sway bar link has a 10mm diameter mounting pin/stud, which is the typical factory/stock size for a universal fitment. These are sold by the pair, and each set includes two matching sway bar end links.

These end links offer the quiet operation and long life of "stock" BMW end links, but with the strength and adjustability of rod-end style sway bar links. These sway bar links can be used on a wide variety of BMWs and aftermarket BMW suspensions. When measuring, please consider that the length ranges of our Custom Adjustable end links are measured from the center to center on the end link mounting stud / pin, as shown in our diagram.

Note for E9X M3: the unique mounting on the M3 strut requires a set of our adapter seats (#TSU9912AF9). You can add them with your links from the menu below.

Made in the USA The rear subframe is the heart of the BMW rear suspension. Not only do all of the suspension arms attach to it, the driveline runs through it via the differential and half-shafts. Therefore, a track-prepped E46 should never see any flex or deflection in any of the subframe mounts. Excessive movement here transfers to unwanted suspension motions elsewhere and is also a major contributor to failures in the rear floor sheetmetal.

While our Delrin-Aluminum subframe mounts conform to various racing series these all-aluminum mounts are the ultimate in reducing flex and deflection. The rubber stock mounts, and the Delrin mounts to a small degree, flex and deflect as various forces are applied throughout the subframe - on and off throttle loading, cornering on flat surfaces, bumpy surfaces, weight transfer, sticky race tires, etc. Too much flex from worn rubber mounts will transfer to flex where the subframe meets the chassis/floor. This is the primary cause for the infamous rear subframe failure. These fully solid aluminum mounts have absolutely zero flex to them so they will not contribute to rear subframe issues. The Turner E46 Reinforcement Kit is still recommended.

These solid subframe mounts were designed for racing use only, where we won several sports car championships in the Grand-Am Cup series. These subframe mounts are over-engineered to be a major improvement over the stock subframe mounts not only for performance but also in strength as well. The aluminum is CNC machined for a precise fit and minimal weight. One front bushing is slotted to allow for BMW's manufacturing tolerances. Professional and experienced installation is required.

The stock Genuine BMW rear lower wishbone control arms (33326770813) are great for standard daily driving and occasional spirited driving, but they tend to fall flat on the track due to the soft rubber bushings causing excess deflection, creating undesirable handling characteristics. In order to address this issue, Turner now offers new Performance Rear Camber Arms (V2) with upgraded FK Spherical Bearings! These camber arms offer multiple benefits over the stock control arms, helping to keep your BMW under control and on the track. The upgraded Turner camber arms offer an increased range of rear camber adjustment, necessary for lowered cars and performance alignments to maintain proper rear camber and reduce tire wear on the street and track. This provides increased stability and predictability to the rear suspension for tighter handling. These camber arms feature gun-drilled 2024 Aluminum center links, clamps, and clevises, along with a 360-degree rotating clamp system. This combination provides superior strength, performance, durability, and ease of adjustment. No annoying jam nuts! A simple 3/16" Allen-key is all that is required to lock down your alignment settings. FK Spherical Rod Ends are utilized to reduce alignment change in the rear suspension under hard cornering, acceleration, and braking. They feature a Teflon liner to provide quiet operation, low friction, smooth articulation, and eliminate bushing deflection under load. The PTFE liner is chemically bonded to the inner diameter of the race, offering a very high load carrying capacity and greatly increased dynamic wear characteristics. This results in robust reliability for and track use! (Not recommended for street use due to increased NVH) Adjustable Rear Camber Arm Features: Lightweight Aluminum and Stainless Steel construction Anodized Blue for corrosion protection and durable finish Gun drilled center hex links for maximum weight savings Teflon lined FK Rod Ends

The E36/E46 rear trailing arm bushings (RTABs) wear out faster than any other bushing on the car. Worn RTAB will cause excessive toe alignment change and give a 'loose' or 'floaty' feeling in the rear handling. One of the reasons for this is that they over-extend during motion, stretching and twisting the rubber in all directions. These shims sit on either side of the bushing and limit the amount of extension from the bushing. Not only will you get more life from your RTAB but these will help stiffen the bushing during cornering. But during normal driving you will still have all of the comfort of the stock rubber bushings. These part about these bushings is how easy they are to install - simply slide them in place during your bushing install. They can be added to pre-installed bushings too by dropping the trailing arm and removing the cage around the bushing.

Works with stock rubber bushings only (not urethane or Delrin).

Our experience with spherical front control arm�ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).��We wanted to offer e30, e36, and e46 owners similar levels of handling precision and control for the track and street, but weren�t satisfied with the other options out there.� Instead of a Delrin bushing or unsealed spherical bearing alone, we selected an oversized sealed greaseable spherical monoball to offer unparalleled durability and precision, but designed a Delrin adapter sleeve to help isolate the added noise, vibration, and harshness that a full solid monoball bearing will have.�While race-ready,�our hybrid Delrin/monoball control arm bearings are more at home on the street than other kits that are advertised as��race-only� bearings. We did extensive street, autocross, and track testing to ensure the spherical bearing used in this bushing design excelled in each setting.

The stock rubber bushings, even�those found in the M3,�allow significant fore/aft movement of the front wheels to help absorb road impacts, especially when being pushed hard. �This soft flexible design maximizes daily driving comfort, but also allows considerable alignment change.� This unwanted deflection�stands between you and a crisp, confidence-inspiring driving experience. �The advantage of a monoball bearing is that it will not deflect under load, eliminating all unwanted deflection while still allowing�complete freedom of movement�in the desired angles. What you get is superior steering precision with better handling from more consistent alignment�and direct braking feedback, with exceptional service life.� Thanks to the�Delrin insert and double lip seals, there's none of the extra noise or reduced service life�often�found on�other�spherical bearings.

In short, if you're seeking front control arm bushings that offer precise, predictable handling, crisper braking feel, with a long service life free from noise - look no further. We have you covered.

Here at Turner we understand the importance of an upgrade that will get the results you need on the track and still be tolerable on the drive around town. When it comes to control arms on the track, making them as stiff as you can (usually using solid mounts) is the best way to increase your driving precision by eliminating the deflection of rubber. The next best thing to create a balance would be to stiffen up the control arm with polyurethane, giving you the option of a more stock like feel with 80a or closer to the solid feel with 95a durometers. These poly bushings will give your control arms a direct connection between your suspension and the body of the car eliminating the slop felt under take-off and braking so you feel more in control of your vehicle. 

This item fits the following BMWs that use a centered-style bushing: 

1999-2005 E46 BMW 323i 323ci 325i 325ci 328i 328ci 330i 330ci - not for xi models

Our Rod-End Camber Arms deliver the ultimate in precise camber adjustments and a free-motion design, thanks to the finest rod-end bearings available. We use high-quality stainless, PTFE-lined bearing joints made by the best manufacturers in the business. These bearings are self-lubricating with a PTFE fabric liner for long life and quiet operation. The bodies and threads are heat treated stainless steel. Without spending hundreds of dollars per bearing, these are the best on the market.

Over time, and depending on use and application, the bearing can develop play which does not adversely affect the performance but will make a "clicking" noise. We have a spec tolerance of .015" before recommending replacement. The bearing itself will continue to rotate freely and the camber arm will function as normal. But should you want to replace the rod-end because of the noise, or to meet track inspection requirements, we offer this replacement end. As far as we know this rod-end fits only our BMW rear camber arms and no other brand, although it may have other applications. Price is per rod-end.

This item fits the following BMWs:

Fine-tuning your coilover damping shouldn’t mean stripping out your rear seats or interior panels. On many applications, rear shock adjusters are hidden behind carpet, trim, or seatbacks, making quick adjustments a hassle.

The ECS Rear Damping Extension Kit solves that problem with a clean and functional solution. These flexible extensions relocate the adjustment knobs to an easily accessible point above the rear shock towers, letting you dial in your suspension from inside the cabin, no disassembly required.

Installation is straightforward: simply drill a small access hole in your interior trim and route the extension cables through. The adjustment knobs can be removed to allow the line to pass through smaller openings, minimizing cutting. For proper installation, be sure to fully loosen the set screw, insert the cable, then securely tighten it using the provided Allen key.

Kit Includes:

(2) Rear damping adjuster extension cables

Installation hardware and Allen key

A smart upgrade for track cars, daily drivers, or anyone who values easy access to suspension tuning, without compromising interior fit and finish.

You get the best of both worlds with this pair of Turner Motorsport adjustable sway bar links. We searched far and wide to find the hidden gem of swaybar links. You get the same quiet operation and long life as the stock links plus the strength and adjustability of rod-end style sway bar links.

With the wide range of suspensions and sway bars available today adjustable sway bar links can help you with many problems. Along with the ability to remove preload you can change the length to maximize sway bar geometry. Example: if the sway bar hoop comes too close to the steering rack, oil cooler, or under tray in its suspension travel you can adjust it by simply lengthening or shorting the adjustment rod. In some cases you may need a longer or shorter adjustment rod to achieve optimal geometry. We also offer these same links in other custom lengths (click here) that may not be specific to BMW chassis.

Features:

  • Adjustable to neutralize preload on sway bar (balanced handling)
  • The ability to set sway bar geometry and clearance
  • Low friction ball joints
  • High articulation
  • Direct replacement for OEM sway bar links
  • Watertight boot seal
  • Ball joint is made by a world leader in ball joint technology, THK. THK's OEM Customers: BMW, Porsche, Ford, GM, Nissan, Honda, and Toyota

Turner Swaybar Link Specs:
TSU9912AF1: 220.00mm - 235.00mm / 8.66" - 9.25"
TSU4612AF3: 250.00mm - 265.00mm / 9.84" - 10.43"

BMW has long suffered issues with rear shock mount blowout on M3 and non-M 3 Series models dating back to 1984 with the E30 chassis. Little changed over the following two decades, and E36, E46, and Z3/Z4 models are also prone to this style of failure. After striking a pothole or another seemingly innocuous obstacle, a clunking from the rear emerges and handling becomes sloppy. Your shocks have blown through their mounts. Enter the Ultimate Performance Rear Shock Mount Kit from ECS Tuning. Not only does their industry-first design alleviate the blowout problem once and for all, but allows rear dampers to fully articulate, for the best possible damper performance and longevity. They accomplish this with no noticeable increase in noise, vibration, or harshness (NVH) thanks to their unique rebuildable polyurethane isolation. The poly bushings not only keep NVH to a minimum, but they also reduce impact loading on the bearing, improving bearing life over full solid mounted monoball designs. To further improve bearing life and longevity, this design incorporates a lower dust seal to keep road debris, grit, and other contaminants out of the bearing. These are one of the best rear shock mounts available, and the last you will ever need. Features: Maintenance-free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation Lower dust seal for improved bearing life 80A polyurethane isolation bushings for NVH control and improved bearing life Accommodates 10mm* Fully constrained shaft mount makes blowouts impossible Hard anodized 6061-T6 construction Class 10 black zinc plated studs New OEM lock nuts included Fully rebuildable design *For use with factory-style 10mm damper shafts. If you have factory-style mounts presently, you have 10mm damper shafts. *During installation a 17ft-lb torque spec is required to avoid damage to the mounts.

This single swaybar link is adjustable to eliminate preload on the front sway bar in E30 M3, E36 M3, E46, and Z4 models. Preload is tension on the bar when the car is at rest on the ground. Ideally, the bar should be neutral with zero tension on both ends (no twist in the bar at rest). Preload comes from inconsistent side-side ride height (such as with coil overs), a bent swaybar, a bent strut housing, or a chassis with bent or skewed frame rails. The handling is affected with a preloaded sway bar so removing that tension will give you more consistent handling and response. Preloading can also lead to premature failure of the link ball joints.

To remove preload you only need an adjustable link on one side of the car. Install your stock swaybar link on one side, lower the car to the ground, adjust the Turner link to meet the swaybar hole on the other side, and tighten everything up. Never install both sway bar links with the tires off the ground. Our link is made from a stock HD swaybar link with an easily adjusted hex rod in the middle.

One link or two? Technically, the remove preload only one link is required. However, there may be cases where having two links is better. Having an adjustable link on both sides of the car will allow you to better position the front sway bar for clearance or when a different racing style coil over is used.

Want a race-spec rear shock mount but with the comfort of a factory bushing? This ECS rear shock mount combines the precision and articulation of a spherical bearing with the isolation of urethane bushings. The stainless monoball bearing is lined with PTFE lubricant and suspended in 80A urethane and housed in a hard anodized 6061-T6 aluminum mount. The spherical bearing is a better design than most rear shock mounts because it allows the shock to move and tilt without side-loading the shock shaft (which leads to premature failure of the shock). Most Genuine BMW and aftermarket shock mounts are not designed for shock angles and the stress that track or performance driving will put on the shock shaft. The ECS shock mount is properly designed to handle these loads. The internal bearing is also replaceable - it will be years before you have to replace the entire mount. The ECS mount is fully encapsulated to prevent the common shock mount failure of the stock mount design.

ECS RSM features:

  • Maintenance free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation
  • 80A polyurethane isolation bushings for NVH control
  • Accommodates 10mm, 12mm, or 14mm damper shafts
  • Fully constrained shaft mount makes RSM blow out impossible
  • Hard anodized 6061-T6 construction
  • Fully rebuildable design

* - the RSM comes with the BMW standard 10mm shock shaft bushings. 12mm is used on some performance shocks and 14mm is used on some true motorsport rear shocks.

Here at Turner we understand the importance of an upgrade that will get the results you need on the track and still be tolerable on the drive around town. When it comes to control arms on the track, making them as stiff as you can (usually using solid mounts) is the best way to increase your driving precision by eliminating the deflection of rubber. The next best thing to create a balance would be to stiffen up the control arm with polyurethane, giving you the option of a more stock like feel with 80a or closer to the solid feel with 95a durometers. These poly bushings will give your control arms a direct connection between your suspension and the body of the car eliminating the slop felt under take-off and braking so you feel more in control of your vehicle. 

This item fits the following BMWs that use a centered-style bushing:
