Includes both brackets and all new installation hardware. The stock aluminum sway bar brackets in the E39 5-Series suffer from a serious design flaw that has resulted in many people experiencing snapping and misshapen brackets, a mounting tab that is simply too weak. Not only was the OE bracket not designed to handle the loads required, but the aluminum construction was also easily fatigued over time, making an already questionable bracket weaker over time. This sub-par construction eventually leads to the mounting tab breaking off, releasing all tension on the sway bar, causing sloppy handling feel and knocking noises in the rear of your BMW. Luckily for all of us, the fix is simple. By swapping the construction from aluminum to steel, while maintaining all of the original dimensions, these brackets offer 3 times the mounting strength versus the OE brackets! This ensures that no matter how many track days or spirited weekends of driving your BMW sees, you can rest easy knowing your rear sway bar is securely mounted. To top it all off, these brackets are also zinc-coated, keeping away rust and corrosion for years. Why go steel E39 brackets instead of using E38 brackets? Fitment. Although the E38 bracket is a commonly suggested upgrade, it does require a bit of modification to fit properly and usually results in a bit of bushing compression, making your sway bar difficult to install.

Looking to improve your car's handling in the corners? ECS Tuning's rear non-adjustable sway bar is a cost-effective way to limit body roll and keep your wheels planted when entering a corner at higher speeds. Sway bars are a great way to improve handling without sacrificing ride quality or reliability! Sway bars are typically sold as a front and rear set to balance the handling. But a rear sway bar only can also have excellent benefits, especially on a street car. Going with a larger rear bar will improve steering and handling even at low-moderate speeds. ECS has specified a 15mm sway bar that has been fine-tuned for use on the E9X and E82 models. Urethane bushings with a reinforced inner core that requires no lubrication are included.

If you're looking to take on corners more aggressively, consider upgrading to thicker sway bars. Thicker sway bars provide increased stability, minimize body roll, and ensure better traction on the road, allowing for more confident and aggressive cornering. The best part is, you can enjoy improved handling without sacrificing your ride quality.

Whether installed on a MINI Clubman or Countryman, or a BMW X1 or X2, the GT Sway Bar enhances cornering stability and responsiveness in a way that rivals, and in some cases exceeds, the benefits of lowering springs or coilovers alone. The result is a more planted rear end, improved rotation through corners, and a chassis that feels tighter and more predictable under load.

Crafted with a mandrel-bent chromoly heavy-wall tube, the NM Eng Anti Sway Bar ensures consistent diameter for precise torsion motion. Its forged ends with two adjustment mounting holes, billet 7075-T6 aerospace-grade sway bar bracket, 90° Zerk fitting for easy re-greasing, and graphite impregnated urethane bushing ensure durability and performance. The glossy blue powder-coat finish and 3-way adjustable preload make it ideal for aggressive urban driving, canyon carving, and track/autocross use.

Please note: The NM Engineering Sway Bar Link kit is recommended for optimal performance when used with the GT Sway Bar.

  • Improved body roll management
  • Enhanced handling and steering input
  • Ideal for aggressive urban driving, canyon carving, and track/autocross applications
  • Durable construction for long-term use

We put together this special sway bar set for the SpecE46 racing class (SE46) and any other E46 that gets heavy track time. We use the 30mm M3 front bar combined with the 21mm E46 non-M rear bar. From our time racing the E46 in World Challenge, Grand-Am, and SCCA club racing we found that the E46 likes a stiffer sway bar and less spring rate. Taking the M3 front bar, which is solid, is exactly what we wanted. They are adjustable in the front (3-position) and the rear (2-position) to fine tune the handling. Bushings are included and new adjustable links are optional. These bars are crafted from a special spring steel that is both stronger and more resilient than competitive sway bars. They have been shot peened and heat treated, and feature precision forged ends.

Setup: The bars are adjustable so any driver can find an ideal setup for the type of driving they are doing. The sway bar becomes stiffer in the holes furthest from the end of the bar. The holes at the very end of the bar are the softest setting. We would generally recommend starting out with the front bar set to the stiffer setting and the rear bar positioned in the soft setting. Adjust to your liking from there. When using these in a non-SE46 setup (or other struts beside MCS) the strut housing may have to be rotated in the spindle so that the sway bar link lines up better with the sway bar tab on the strut.

Adjustable sway bar links are strongly advised to ensure that there is no pre-load on the bars. And to position the bar so that it has the correct clearance to other suspension components. Pre-load is when the bar is slightly stressed when it's on the car, from differing ride heights or from the chassis being slightly twisted. With the SE46 coil overs the adjustable links are a smart idea. If you have to force the links to fit the bar because it has tension then you have pre-load. Adjustable front or rear links can be added from the options listed below.

This item fits the following BMWs:
1999-2006 E46 BMW 323i 323ci 325i 325ci 328i 328ci 330i 330ci

The ECS Tuning Billet Rear Sway Bar Mounting Kit was designed, engineered, tested and quality inspected thanks by their Research and Development team in Wadsworth, Ohio facility. ECS ensures that the highest level of precision and quality is delivered throughout rigorous long term product testing and leading edge product development methods. This kit provides your vehicle with a more rigid mounting solution from the sway bar to chassis than the OEM steel brackets. With an improved sway bar mounting bracket and the included polyurethane sway bar bushings, you can expect to achieve an increase in rear sway bar effectiveness and less body roll as a result.

For the M5 3.8 BMW offered an optional Nurburgring handling package with this 20mm rear sway bar. This is currently the biggest rear sway bar available anywhere and is a direct bolt-in replacement for the stock or aftermarket bar. This bar is complete with new rubber bushings with new brackets and links optional.

The larger bar will make the suspension stiffer than before, with less roll and less understeer. The larger rear bar will actually make the rear end rotate easier making the car more agile in tight corners. If you have stock E34 (non-sport) swaybars on now this 20mm Nring bar will be a huge difference. If you have an E34 sport suspension, E34 M5, 540i M Sport, or aftermarket cars the difference will be smaller. But since BMW installed this as part of a factory handling package it will be an improvement for track, autocross, or backroad handling.

Included in this package:
  • 33552227416 - E34 M5 3.8 Nurburgring 20mm rear swaybar
  • 33552227240 - 20mm rear swaybar bushings
  • optional 33506779734 - rear swaybar bushing brackets (not required but get rid of those rusty original ones!)
  • optional 33551135307 - rear swaybar links
    This sway bar upgrade fits the following BMWs:
    1989-1995 E34 BMW 525i 530i 535i 540i M5
