Enhance Cornering Performance with Thicker Sway Bars

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.

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.

Sway bars are an essential upgrade when trying to get the best handling capabilities out of your BMW. Stock sway bars allow for too much play and excessive body roll, not keeping the wheels as firmly planted as they should be. Whiteline offers their performance sway bar kits that are designed to improve your BMW's handling characteristics and come with upgraded polyurethane bushings as well.

This Whiteline 20mm sway bar gives you more grip, better handling, and better outright performance. Sway bar upgrades are one of the best dollar-for-dollar investments you can make, improving your BMW's handling dynamics without affecting the comfort or ride quality.

This part fits the following BMWs:
