2019+ BMW 3 Series (G20) M Sport Style Rear Bumper Conversion



Frequently Bought Together





We are currently offering the 6 PDC hole version of this bumper and 4 PDC version. We will eventually ONLY offer the 4 PDC option and if you have 6 PDC sensors, you will need to drill the last 2 holes on your own (the bumpers are marked in the back on where you need to drill).


This is the PhaseOne M Sport style rear bumper conversion for your G20 seventh generation BMW 3 series. This will fit any of the G20 BMW models including the 330i and 330e (xDrive, eDrive, and diesel variations as well).

This conversion will elevate your 3 series to the next level, for that aggressive looking M Sport package you've always wanted without the factory price tag. It is probably one of the most dramatic upgrades you can do for your BMW 3 series if you did not pick up the M Sport package directly from the dealership.

Constructed from the same materials as OEM with excellent fitment, this rear bumper conversion is an effective way to execute the M Sport upgrade without having to spend an arm-and-a-leg.

Please make you select the appropriate bumper options. Our kits are very comprehensive so it is imperative that you make accurate selections so that we can accurately fulfill your order.

NOTE about the Diffuser: The bumper conversion comes standard with a 330i M Sport style diffuser (no fins, no grooves, just a nice clean look with rounded exhaust cutouts). There is an option to upgrade (for an additional cost) to the 330i M Performance inspired design diffuser (has fins and looks more aggressive with angular exhaust cutouts). There is also an M340i diffuser upgrade option which also has angular exhaust cutouts with an even more aggressive fin design. If you are upgrading from an 330i, you will need to modify your exhaust if you want to equip the M340i Performance diffuser.

Base vs M Sport?

A picture is worth a thousand words. Take a look for yourself to see if the aesthetic improvement is worth the upgrade to you. To each their own. We don't judge! We just want you to be happy and make an informed decision. The bottom is

Why PhaseOne?

Is Quality, fitment, and durability important to you?
Our industry leading manufacturer uses some of the most cutting edge technology, coupled with over 20+ years of experience to craft the highest quality, best fitting body panels so that the conversion process is painless and the end result is simply beautiful.

PhaseOne kits are constructed using the same materials that OEMs use to manufacture their body panels.

  • Bumpers are crafted using polypropylene thermoplastics, a highly durable and flexible material.
  • Fenders are crafted from quality-grade steel.

DIY Instructions:

Disclaimer: Although these kits can be installed on your own (DIY) we highly recommend that you utilize an experienced body shop to perform the labor. A professional body shop can be the difference maker between a good or bad result.

As best practice when looking for a shop, you should ask to see results of their previous work. If they claim to be experienced but have no tangible evidence, we would recommend caution when taking your business there. Kiesmotorsports is NOT responsible for poor labor practices.

If you have any questions or concerns, please don't hesitate to contact us. An informed / educated customer is a happy customer.

Your satisfaction is our priority, and we look forward to serving you!

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.
