About the M3 / M4 PSM Inspired carbon fiber rear diffuser:

This exquisite M3 / M4 PSM carbon fiber rear diffuser is a beautiful work of art that fits perfectly onto the F80 generation M3 super sedan.

It also fits the F82 generation M4 super coupes, and the F83 generation convertible as well!

This rear diffuser not only looks amazing, it's also aerodynamically designed to efficiently channel air and reduce drag. So not only does this upgrade look good, it is also functional.

For anyone looking to upgrade their stock M3 or M4 with an aggressive yet practical, sturdy yet light weight carbon fiber rear diffuser, look no further!

This is a 4-piece design and professional installation is highly recommended.

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