HT Autos Matte Black Side Skirt Extensions for 2015 - 2021 Subaru WRX/STI

These side skirt extensions are a great addition to your 2015 - 2021 Subaru WRX or STI. Here's how to use them. First, since professional installation is recommended, it's best to have a pro handle the job. But if you're doing it yourself, start by cleaning the area where you'll attach the extensions. The 5 pre - drilled holes on each side are there to help with alignment. Use the included 3M double - sided adhesive to stick the extensions firmly. Just be aware that some modifications might be necessary for a perfect fit. As for maintenance, keep them clean with regular car washes. The tough polyurethane construction can handle a bit of wear and tear, but try to avoid hitting curbs or other hard objects to prevent dents and dings.
