The Kies Carbon Aero carbon fiber side skirt extensions were designed to fit multiple BMW models, including the F80 BMW M3, F82 & F83 BMW M4, F30, F31 BMW 3 Series, F32, F33, and F36 BMW 4 Series! These are installed right below the stock side skirt rocker panels and adds an incredibly clean stance to your vehicle!
These are a perfect match to complement any other carbon fiber aerodynamic parts you may already have on your BMW, or simply as a modder's first upgrade. They are very simple and straight forward to install. No matter what, these side skirt extensions are sure to please any enthusiast and will definitely turn heads.
There is a level of flexibility when it comes to installing these extensions, and depending on how far our you'd like the lip to protrude from your side skirts, some trimming may be required (please see the DIY video below). The choice is yours!

Why Kies Carbon & PhaseCarbon?
If quality, fitment, and durability is important to you, look no further than Kies Carbon and PhaseCarbon aerodynamics.
PhaseCarbon contains some of our mainstream products, while Kies Carbon contains some of our more exclusive line of carbon products. Both brands are expertly crafted by our industry leading manufacturer (with 20+ years of experience & cutting edge technology). Doing so, we have been able to create some of the highest quality, best fitting aerodynamic parts on the market. The end result is an elegant and beautiful piece worthy of one's marvel.
- » Industry standard, high quality carbon fiber woven fabric serves as the foundation of our standard carbon fiber products (forged carbon uses a different process)
- » Standard thread weight is 3K and is woven in a 2x2 pattern - one of the most popular patterns found on carbon fiber parts today (some parts may be 1x1, honeycomb, or other unique weave patterns)
- » Our forged carbon is a very unique style where no two pieces look exactly alike. They are created from pressed carbon composite materials rather than continuous sheets of carbon fiber, which gives each that its own unique look.
- » We finish our carbon products with a hardy anti-UV high gloss clear coat that will be sure to stand the test of the elements, as well as the test of time
Only the best can wear the Kies Carbon or PhaseCarbon moniker.
Disclaimer 1: Although these parts 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. Kies Motorsports is not responsible for poor labor practices.
Disclaimer 2: Product design may change from time to time. Pictures are a representation of the design during that time frame and may not reflect new changes in design. Design changes and improvements will be minor, but overall look and fitment will not change. Here are Kies Motorsports, we're constantly working to improve on our products through R&D testing and customer feedback to provide our customers with the best possible solution.
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.
