2012-2018 F30 & F31 BMW 3 Series M Performance Style Carbon Fiber Rear Diffuser

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

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

Our carbon fiber M Performance style rear diffuser will fit any 2012-2018 BMW 3 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 conversions.

Yes, this does fit the LCI (facelifted) 330i or 340i as well, rejoice!

PhaseCarbon aerodynamic upgrades are constructed from industry standard 2x2 weave 3K carbon fiber fabric for a clean look and superb strength. It is also finished with a long lasting, high quality gloss coat finish so your parts will not only look good, but last the test of time.

Note: Please make sure you select the right exhaust option for your particular application (420i, 428i, 435i or quads).

DIY Instructions:

Although this DIY video demonstrates the dry carbon fiber diffuser, it will be very similar for the normal carbon fiber diffuser as well. Videos are for guidance only, however, we always recommend having your carbon fiber parts installed by a professional.

We are typically very quick and have a 24-48 hour turnaround time. 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.

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. 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 (with the exception of crank hubs - we still do thos inhouse). Our HQ is solely reserved for filming, office space, and shipping/receiving.
