Using these AMS Performance mud flaps is simple. Just find the OEM bolt holes on your 2022 - 2025 Subaru WRX and mount the mud flaps without any cutting, trimming, or drilling. They're designed to snap right in, and you'll be back on the road in no time. Remember, these mud flaps are made of semi - rigid ABS plastic, so they're not meant to bend or flex like rubberized ones. Also, they won't fit if you have OEM aero splash guards installed. For maintenance, just wash them with mild soap and water regularly to keep them looking good and functioning well. This will help them continue to protect your vehicle from road debris and keep your car looking great.
