Aerodynamic Parts
Aerodynamic Parts: manage airflow front to back, not just looks
Aerodynamic parts change how air moves over, under and around your vehicle. A front splitter and chin spoiler slow and split the air hitting the nose, cutting front-end lift so the steering feels more planted at speed. A gurney flap adds a small lip to a wing or trailing edge to build downforce, while a wind diffuser and shrouds tidy up airflow behind wheels and bodywork. Fit one because you want more front bite, cleaner high-speed manners, or the finished aero look to match the function. This category collects those pieces in one place.
What ThreePiece stocks in this category
There are 9 products here from 5 brands: AWE Tuning, Kuryakyn, Anderson Composites, Roush and Ford Racing. The current in-stock price range runs from $59 to $1,187 — a snapshot of what's live now, not a locked-in quote. Fitment data covers Ford, Porsche, Toyota and Honda, across model years from 2001 to 2024, on vehicles including the Ford Mustang, Toyota GR Supra, Porsche 991, 981, 718 and 992, and the Honda GL1800.
Concrete examples: the Anderson Composites carbon fiber front splitter wickers for the 2020 Mustang/Shelby GT500 sit at the top of the range, with the matching carbon fiber gurney flap alongside it. For a bolt-on kit, the Roush 3-piece chin spoiler and wheel shroud kit covers 2018-2023 Mustangs. For Porsche, the AWE Tuning Foiler wind diffuser fits 991 / 981 / 718 chassis. Riders are covered too, with the Kuryakyn Precision chin spoiler for M8 Softails and the Kuryakyn Dragon Wings for GL1800 models.
How to choose
Start with your vehicle, then the job. Carbon fiber pieces like the Anderson Composites splitter and gurney flap sit at the high end of the price spread and pair front and rear aero together. A single bolt-on chin spoiler or the Roush 3-piece kit is a middle-ground choice when you want a finished front end without committing to a full carbon build. The AWE Tuning diffuser is a targeted, lower-cost addition rather than a complete kit. On the motorcycle side, the Kuryakyn spoiler and Dragon Wings are cosmetic-and-airflow parts specific to Softail and GL1800 platforms, so match the model exactly. Buy front and rear pieces as a pair when you can — adding downforce at one end only can shift balance.
What else you'll want
Aero rarely goes on alone. Browse the broader Exterior section for the pieces that round out a build: Mud Flaps to protect painted lowers behind the wheels, Lighting and Tail Lights to finish front and rear, and Tow Hooks for track-day recovery points near your new splitter.
