Side Skirts: Aero Upgrades for Euro & JDM Builds
Side skirts run along the lower rocker panels of your car, connecting the front and rear bumpers into a clean, continuous line. They're one of the most effective aero parts you can fit: blocking turbulent underbody airflow, improving high-speed stability and giving your car that planted, wide-stance look that separates a built car from a stock one.
At AusBody Works, we're Australia's official distributor of Maxton Design side skirts, the brand trusted by Euro enthusiasts worldwide, exclusively available in Australia through us.
What Do Side Skirts Do?
Side skirts aren't just a cosmetic upgrade. The aerodynamic benefits are real:
-
Reduce underbody turbulence — limiting the chaotic airflow at speed
-
Improve downforce — helping your car sit flatter and track cleaner through corners
-
Lower visual profile — giving your car a wider, more aggressive stance
-
Protect rocker panels — a physical barrier against stone chips, road debris, and kerb scrapes
For the full ground-effects look, pair your side skirts with a front lip or splitter, a rear diffuser or a boot spoiler.
Materials: ABS vs Polyurethane
Our side skirts come in two materials depending on the fitment:
-
ABS plastic — rigid, easy to paint, holds shape well under heat
-
Polyurethane — flexible, impact-resistant, ideal for low-clearance cars or rougher roads
Both are lightweight, durable and designed to take paint or wrap without prep drama.

Frequently Asked Questions
What is the purpose of a side skirt?
Side skirts are fitted along the lower sides of a car to reduce turbulent airflow passing underneath the vehicle. This improves aerodynamic efficiency, increases downforce at speed and gives the car a more aggressive, lower visual profile. They also help protect the rocker panels from road debris.
What are side skirts called?
Side skirts are also known as rocker panels, side splitters, side extensions, rockers, or ground effects. These terms are often used interchangeably. "Rocker extensions" typically refers to OEM or OEM-style parts while "side skirts" usually describes aftermarket additions.
How do I choose the right side skirts?
Always choose model-specific side skirts over universal-fit parts. Factory-fit options sit flush and require minimal modification. Then decide on material (ABS for a firm, paintable finish; polyurethane for flexibility) and a style that suits your existing or planned bodywork. If you're building a full kit, choose skirts from the same range as your front lip and rear diffuser for a seamless, matched look.
Do side skirts reduce road noise?
Side skirts can slightly reduce road noise by managing airflow around the lower body of the car, but they are not a noise-reduction product. Their primary benefits are aerodynamic and visual.
