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
