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.

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

    If you want to be able to handle corners more aggressively, you can start by adding thicker sway bars. A thicker sway bar will be less apt to bend and distort and will keep your wheel more solidly planted to the pavement. You will experience less body roll, with almost no sacrifice in ride quality
