Side Skirts Installation GuideUpdated a month ago

Tools Required

• Cleaning supplies (microfiber towel, isopropyl alcohol)

• Masking tape

• (Optional) Jack and jack stands for better access

1️. Preparation

• Clean the rocker panels (area under the doors where the skirts attach).

• Wipe down with isopropyl alcohol to remove grease or wax.

• If you’re using tape, apply it to the inner edge of the side skirts now but don’t peel the backing off yet.

2️. Step-by-Step Installation

• Lift the Car (Optional but Helpful)

• Use ramps or jack stands to raise the side of the car for easier access to the underside.

• Test Fit the Side Skirts

• Hold the carbon fiber skirts up to the rocker panel to see how they line up.

• Use masking tape to mark the alignment if needed.

• Make sure they fit snugly front to back and don’t interfere with the wheels or undertray.
  
  

3️. Tape and Position the Skirts

• If using tape:

  • Peel a few inches of the tape backing on each strip.

  • Stick the skirt in place while keeping the full backing on (use the peeled ends to help position).

  • Firmly press the skirt against the rocker panel to stick the tape down.

4️. Drill and Screw (Main Fastening Step)

• Once aligned, use a drill to pre-drill small pilot holes underneath the rocker panel (not visible).

• Secure the skirt using self-tapping screws.

• Start from the center and work outward for even fitment.

• Be careful not to overtighten. You don’t want to crack the carbon fiber.

5️. Final Fit Check

• Re-check all screw connections and tape adhesion.

• Wipe off any fingerprints or smudges from the carbon fiber.

• Make sure the skirts are snug and flush along the body line.
