A worn or collapsed rear shock mount introduces unwanted play into the rear suspension, leading to rear end instability, imprecise handling through turns, and annoying cabin rattles. Installing this OE-grade Rein rear shock mount stabilizes the shock absorber shaft, restoring firm damping control and preventing severe suspension impacts from transferring into the body structure.

Elevate your BMW's handling dynamics without sacrificing the refined ride quality you enjoy every day. This upgrade kit utilizes the front control arms originally engineered for the E90 M3 and E82 1M, providing a sophisticated enhancement to your suspension geometry and overall steering precision. While many aftermarket performance options rely on harsh polyurethane or noisy heim-joint bushings that trade comfort for track-focused rigidity, these M3 components offer the ideal middle ground for a spirited daily driver. Unlike the factory Non-M control arms that utilize fluid-filled bushings prone to cracking and leaking over time, these high-performance replacements feature solid rubber bushings. This design significantly reduces control arm deflection and sharpens front-end feedback, ensuring your vehicle feels more planted and responsive during cornering. Sidem has refined this setup even further by reinforcing key areas of the original factory design, resulting in a more durable and reliable component that stands up to the rigors of the road while maintaining a smooth, factory-plus feel.

One item to replace is the control arm. After years of service, the non-serviceable ball joints and other components can begin to wear out. Because some components cannot be replaced, the only solution is replacement of the entire arm.

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

    A degraded or soft front strut mount introduces excess movement at the top of the strut assembly, compromising handling precision, steering feel, and tire contact under hard cornering. This OE-quality Rein strut mount restores solid structural support at the strut tower, keeping your front dampers properly aligned and operating with maximum responsiveness.
