Installation
- Gather tools: panel pop tool, Phillips screwdriver, body panel adhesive (optional), and painter’s tape.
- Clean the rocker panel surface thoroughly and allow to dry before installation.
- Pre-fit both side skirts against the rocker panels without fastening to confirm alignment. Compare left-right symmetry.
- Identify OEM rocker panel clip locations or apply body panel adhesive tape to the mounting flanges as directed by the fitment instructions.
- Starting from the center, work outward toward each end and press the skirt firmly into position.
- Secure with push-clip fasteners at factory locations or apply light body panel adhesive at contact points for additional retention.
- Allow adhesive to cure per manufacturer instructions before driving.
- Inspect skirt-to-door gap alignment. The skirts should sit flush with the lower door line.
Frequently Asked Questions
Are both side skirts included?
Yes. The product includes driver and passenger side skirts as a matched pair.
Do I need to permanently modify my vehicle?
No permanent modification is required. Seibon side skirts attach using OEM-style push clips at factory rocker panel locations. Some installers use body panel adhesive tape for additional retention without drilling.
Do these require painting?
No painting is required for the carbon fiber look. The gloss clear coat is factory-applied and UV-resistant. For color-matched finishing, a body shop can paint over the existing surface after proper preparation.
What is the warranty?
Seibon provides a fitment guarantee and a 6-month limited clear coat warranty. Under the Magnuson-Moss Warranty Act, installing aftermarket side skirts does not void your vehicle’s factory warranty on unrelated components.
How do I care for the finish?
Wash with mild soap and a microfiber cloth. Apply UV-protectant wax regularly. Side skirts are low to the ground and exposed to road debris; inspect periodically for chips and address promptly to prevent moisture intrusion into the fiberglass backing.
Can these be installed at home?
Yes, with basic hand tools and panel pop tools. Installation is straightforward for experienced DIY enthusiasts. Seibon recommends pre-fitting before any drilling or permanent attachment.
Will these fit on a lowered vehicle?
Side skirts are designed for stock-height vehicles. On lowered vehicles, ground clearance may be reduced. Measure your ride height before purchasing to confirm adequate clearance.
What if the skirts don’t align perfectly out of the box?
Minor fitment adjustment is normal for any aftermarket body panel. Seibon’s fitment guarantee covers significant gaps or misalignment beyond normal adjustment tolerance.
