PhaseOne M-sport style rear bumper for your 2014+ F32 BMW 4 series coupe or convertible. If you didn't get the M Sport package off the lot, or maybe you got a great deal on a used F32 4 series with the base bumper then we have the solution for you to consider.

TheĀ MĀ 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 that should have been there from the get-go.

Disclaimer: This bumper is NOT designed to fit the F36 Gran Coupe, however customers have been able to successfully install it on their GCs (fitment is acceptable but not picture perfect). If you have a Gran Coupe, please perform this retrofit at your own discretion. Kies Motorsports will not be responsible for any improperly installed bumpers.

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

Diffuser Options:

  • 418i / 420i style (single side, single exhaust outlet)
  • 428i / 430i style (single side, double exhaust outlet)
  • 435i / 440i style (dual side, single exhaust outlet)

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.

We are typically very quick and have a 24-48 hour turnaround time (this applies to products we have readily available at the warehouse and not a product that requires special order). Transit time depends on your order and which warehouse we are shipping from, but typical transit times are between 5-7 business days from one side of the US to the other. Larger items like bumpers and body kit conversions can take up to 10 business days to get you from time of ship.

Majority of the items we offer do ship free to the lower contiguous 48 states. States that require plane or boat to reach (such as Hawaii, Alaska, Puerto Rico, etc) do NOT qualify for free shipping. Larger items such as bumpers, hoods, fenders, also do NOT qualify for free shipping. Please contact us to inquire about international shipping costs. During checkout, you will know which items ship free and which have shipping costs associated with them. In general, larger/heavier items will have additional shipping costs (body kits, wheels/rims, etc)

Even though everything can be shipped internationally, sometimes the cost is simply just too high and doesn't make sense to do so. We're here to make sure you have a great shopping experience, so if you have a product(s) you want to inquire about, please contact us at info@kiesmotorsports.com

Yes, we do price match reputable competitors in the marketplace. If you find a product cheaper elsewhere, please email us the (1) link of the product from our website and (2) the link to the competitor site. We will make an assessment on our end if we are able to price match or not and respond to you via email.

Typically you have 14 days to return a product you purchase when you change your mind. Damaged and improperly installed products are NOT eligible for returns. Shipping fees may be assessed and not refunded based on criteria as well as restocking fees. Please see our FAQ page for more details.

Unfortunate Kies Motorsports no longer does customer installs. Our HQ is solely reserved for filming, office space, and shipping/receiving.
