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.
