PhaseOne M4 style rear bumper for your 2014+ F32 BMW 4 series coupe. This will fit any of the 4 series variations (except M4).

The M Sport rear bumper adds that extra umph to the exterior of your 418i / 420i, 428i / 430i, or 435i /440i (and xi) modern, sport, or luxury line vehicles to give it the same aesthetic appeal as the F82 M4 big brother.

Disclaimer: This bumper is NOT designed to fit the F36 Gran Coupe, however customers have reported it does fit with modifications. Your local body shop should be able to clarify this for you. Purchase at your own risk.

Ours bumpers are made of the highest quality polypropylene for incredible durability, as well as great flexibility. Unlike fiberglass or other cheaper polymer alternatives, polypropylene does not crack easily under stress.

These conversions are also comprehensive, great fitting, and a fraction of the cost compared to OEM. With our bumper kits, you never had to worry about missing parts or incomplete conversions and with the combination of a proper paint job and installation, a picture perfect result is guaranteed.

Note: Please make sure you specify your vehicle options as the following are available depending on what your vehicle is equipped with.

Bumper Options:

  • With or without parking distance controller (PDC) holes


  • This bumper will require customer exhaust modifications to fit. This can be done at your local muffler/exhaust shop.
  • A typical quad exhaust may not fit since the gap between the exhausts openings are different on the M4 compared to a quad exhaust that was designed to fit the F32 M Sport style bumpers.

    If you are ever unsure, please contact us and take a picture of your vehicle and we can help you figure out the details. Our goal is to make sure you make an educated purchase and are ultimately happy with the end result. We pride ourselves on service over profit, satisfaction over transaction. We look forward to serving your needs.
