2011-2016 BMW 5 Series (F10) M Performance Style Rear Diffuser

$248.00 $198.00


The M Performance package is one of the most highly sought after aero-aesthetic upgrades, because the upgrades make such a dramatic impact to the exterior appearance of your ride!

Our PhaseOne M Performance style upgrades serve the sole purpose of attaining that factory look without paying the factory price.

Our F10 M Performance style rear diffuser will fit any 2011-2016 BMW 5 series that is equipped with the M Sport package, and if you don’t have the M Sport package you can look into upgrading with one of our PhaseOne aftermarket M Sport style rear bumper conversion kits.

Whether you have the stock OEM M Sport package from the dealership, of if you have one of our PhaseOne polypropylene body kits, fitment is simply phenomenal!

Note: Please make sure you select the right exhaust option for your particular application (520i, 528i, 535i, 550i). This product comes unfinished in a matte black / grey color. You can chose to install it as is, or you may primer and paint it to the color of your choosing.

DIY Note: It is highly recommended that the rear bumper be removed for the easiest installation and the best fitment. Do not attempt to apply extreme force to try to snap the clips into place. If unsure, please bring your vehicle to a professional. We will not be responsible for any damage that occurs during self-installation.

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

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.
