All sales are final, no returns or refunds. This item does not qualify for free shipping. This product is assembled to order and ships 3-4 weeks after the order is placed.  Made in USA. 

We sell many of these components individually here:


    This kit has been designed so that each component can be replaced, including just half of the blade. Drive off track, bend an endplate or mangle a lower strake on one side? No problem, just swap on a replacement (available here).

    Design & Development
    The YRC & CJM Aero system has been developed over multiple months using CFD (computational fluid dynamics) simulations to maximize downforce, drag and longitudinal stability. YRC performed all of our simulations on a 1:1 MK7 GTI model to gather the most accurate data possible. 

    If you research providers of aerodynamic parts, you may find that many provide only free-stream data for their airfoils, either because their wing was designed to be universal or it yields more impressive numbers when run under ideal conditions. The YRC wing kit has been developed specifically for the MK7/7.5 platform to address some of the unique challenges of adding an effective wing to a hatchback. Our end-mounted airfoil and oversized endplates ensure uninterrupted flow to the aerodynamic surfaces, increasing underwing suction, minimizing drag and improving the overall efficiency of the system.

    To learn more about the steps in our CFD design, simulation and testing process, YRC has a great overview here.

    To learn more about the joint design & development work CJM & YRC did for the MK7 aero kit specifically, check out some of our video content on the YRC YouTube page.


    YRC Wing:


    Designed to complement the lines of the MK7 Golf platform and add class-leading downforce to the rear of the vehicle, this modular wing can be run at angles of attack from 0 - 10 degrees (in 5 degree increments) allowing the flexibility to balance aero upgrades at the front or change your setup from track to track.

    Made from laser cut .100/080 5052 plate & extruded 6061 aerospace aluminum, the main airfoil & dual secondary canards are both strong and lightweight (entire assembly weighs less than 17 lbs!) Wing kit comes complete with endplates, all necessary brackets, Neoprene damping material, slip washers & stainless button-head mounting hardware.

    The airfoil is a highly efficient 55” extrusion with an 8.8” chord and deep cambered profile, offering a drag ratio of between 12.8:1 and 9.08:1 (depending on AOA.) See performance data chart in images below.

    Mounting requires drilling of 8 holes in the factory hatch & spoiler to receive stainless M6 rivet nuts. The entire assembly can be removed from your vehicle in minutes with 10 screws.  

    Each Order includes:

    - Wing foil

    - Wing uprights/endplates

    - Mounting plates & hardware 

    - Printed Install Sheet with pictures

    Special tools required for install (not included):


    CJM V3 Splitter:


    Our results are shown in the table image. 100+ lbs of downforce @100mph. 300 lbs at 130mph.  

    Please read these product details thoroughly for fitment and installation requirements. This can be installed in a driveway with basic tools. Please review the written  install sheet and tool list to understand what is involved in the process, or watch our install video. Professional install recommended if you are not comfortable removing the front crash bar. 

    • Brackets & rods come in raw aluminum unless powder coating option is selected. Expect some visible imperfections in the material from the cutting and bending process on raw aluminum parts.
    • This will not fit with any front mount/twin intercooler.
    • If you are on air ride, do not air-out onto these brackets, they are not designed to support the weight of an entire vehicle. 
    • Requires drilling two 11mm holes in the crash bar for install. 
    • Trimming the factory splash guard under the bumper is required (not the bumper).
    • Brackets are made of 5052 Aluminum, these mount to 6 points of the chassis/crash bar to hold a splitter blade of your choice. They are height adjustable in 12mm increments.


    Each Order includes:

    • Top driver & passenger side bracket
    • bottom brackets with pre-installed hex shank rivnuts for the lip/blade

        We do not provide return labels for orders that ship out of the continental United States. You will have to create your own label to return the product. 

        Our policy lasts 30 days. If 30 days have passed since your purchase, please contact us about the possibility for a refund, store credit or exchange.

        Splitters, chassis brackets, diffusers and side skirts are not returnable or exchangeable.

        To be eligible for a return, your item must be unused and in the same condition that you received it. There are certain situations where only partial refunds are granted.

        25% restocking fee applies to products returned without all original packaging.  We will provide a return label in the first 30 days (since ship date) and deduct the cost of the return label from the refund.

        For example: $75 part + $6 shipping fee = $81 order total. Customer would like to return because they no longer need it, or ordered the wrong part. 

        $75 (part cost) - $14 (return shipping label) = $61 refund.
