Listed for: 2012-2021 BMW 228i, 320i, 328i, 335i, 340i, 428i, 440i and M240iFitment notes & questions

This SuperPro alloy arm kit uses the brand's Supaloy control arms and is listed for a broad range of 2012-2021 BMW models, from the 320i and 328i through the 340i, 4 Series coupes and Gran Coupes, and the M235i and M240i. Lowered and hard-driven BMWs often end up with geometry outside the factory range, and arms like these are how many owners bring it back. A good fit for modified street cars and track-day BMWs.

Fitting complete arms rather than individual bushings saves time and replaces every wear point at once. The result is a front or rear end that feels tighter and more consistent, with alignment settings that hold over time.

Plan the whole job

  • An alignment after installing new arms or bushings.
  • Matching parts at the other end. Upgrading one side or one link and leaving worn parts elsewhere limits the improvement.
  • Install tools. Pressed-in bushings may need a press or a shop to fit them.
