BMW Sway Bar Kits

The next step in tuning your car's handling - after shocks/springs and camber plates - should be a set of swaybars. Using larger front and rear sway bars will give your car better/quicker turn-in and less bodyroll in corners. These bars replace the existing sway bars on the car for a clean and simple upgrade with very little downside. Sway bars should be matched with your springs/shocks to maintain a proper handling balance. In some cases only a front or rear bar is needed to positively change the balance and make the car more neutral. We sell sway bar kits from H&R, Racing Dynamics, OE BMW upgrades, and even some of our own designs. Swaybars are sold with new bushings. New links and other hardware are strongly recommended.

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

    As a bushing deteriorates, so does the functionality of the sway bar. With more play, the anti-roll stiffness the sway bar provides decreases, allowing more body roll and poor handling. Replace yours with an OEM Rein sway bar bushing to restore optimal handling characteristics.

    The sway bar acts as the bridge between your vehicle’s left and right lower control arms, working like a spring as it twists and rebounds through corners. Factory bars deliver factory handling—smooth and predictable. When the sway bar end links are worn or broken, that connection weakens, and your suspension can’t perform as intended. Replacing them with quality Febi end links restores proper function and brings back the crisp, planted feel your car had when everything was tight. Fresh end links mean flatter cornering, reduced body roll, and more confidence in every turn. Common signs of worn end links include loose or floaty cornering, knocking noises over bumps, and a generally sloppy suspension feel. Luckily, replacement is straightforward and well within reach for any DIY enthusiast.
