Side Skirts and Side Steps

Tuning side skirts for a car include add-on side skirts ("skirts"), blade-style extensions that mount under the factory sill, DDCarbon carbon-fiber skirts, and side step running boards for crossovers, SUVs, and pickups; 695 items in this category. Add-on skirts and blades are decorative—you don’t step on them. A proper step is a running board with brackets. Almost everything is made for a specific body, so choose via the “Make / Model” filter.

What’s in this category

• Carbon-fiber skirts and side skirtsDDCarbon made of genuine carbon fiber—mainly for BMW, Mercedes-Benz, Audi, Porsche, Subaru, and Tesla.

Add-on skirt or step: don’t mix them up

The term “side skirts/sills” is used for different things. An add-on skirt and a blade extension are decorative parts: they change the car’s profile, but you don’t step on them. A step is a running board with brackets. If you need that, also check side steps (stainless tubular and aluminum profiles), rock sliders for pickups, and electric retractable running boards. Inner door-sill plates are in a separate section: door sill protectors.

How to choose for your body style

• Confirm the body type: sedan, hatchback, coupe, convertible, or Sportback often have different versions.
• Check which factory sills the add-on is designed for: blades “for M-Sport sills” fit only cars with the M package.
• For vans and long sedans, wheelbase matters—short, medium, long, or Long; for Defender there are separate versions for 90 and 110/130.
• V1, V2, V3 are different designs within the same model, and the years in the title show which body version the part fits.
• For running boards, confirm the market and vehicle version: EU and US variants are not always interchangeable.

Material, painting, and installation

A “paint-ready” part should be test-fitted and panel gaps adjusted first, then prepped and painted to match the body color. Shipping primer is not a final finish. Gloss black can be installed without painting, but the shade may differ slightly from factory black.

Most add-on skirts and extensions are installed with automotive glass adhesive/sealant, and the adhesive is not included—this is stated in the specs. Universal Flap add-ons stick on with self-adhesive backing. Running boards mount to factory locations with an installation kit; LED steps require wiring. Before bonding, clean and degrease the surface, and dry-fit the part first. You can install the body kit at DD Tuning’s network of certified service centers—your manager will point you to the nearest one.

Side skirts are often paired with front bumper lip spoilers, rear diffusers, and fender flare add-ons to make the kit look cohesive.
