RokBlokz Mud Flaps for 2015+ Subaru WRX STI - Multiple Colors Available - Mud Guards are Custom Cut and Fit and Include all Mounting Hardware (Originalz, Red with White Logo) Large design provides your 2015 WRX STI Sedan with excellent protection from harsh road debris and gravel. Light weight and extremely durable, designed to survive the harshest environments from the extreme heat to the extreme cold. Won't crack or warp from temperature extremes. Flexible but with a semi-rigid characteristic that allows them to retain their shape at speed and effectively block tire spray (we're not into flappy mud flaps) . Also helps to resist getting sucked into the tire. Mount using existing OEM mounting locations, no drilling required. Stainless Steel mounting hardware and detailed installation instructions included. 2 sizes to choose from - Originalz or Shortz (The SHORT versions are about 1.5" shorter for greater clearance and less scraping on lowered WRX/STIs. If you're unsure which size to get, go with the short).
