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.

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
2001-2006 SpecE46 BMW 330i 330ci

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
