Maxton Design Street Pro Side Skirt Diffusers for Subaru Impreza WRX STI Mk3 Facelift
Add purposeful style and cleaner side airflow to your STI. These Street Pro side skirt diffusers extend the factory sill line for a lower, more planted look while helping guide airflow along the cars sides.
Designed for the Subaru Impreza WRX STI Mk3 Facelift 2011-2014. Please use our vehicle lookup or check the Vehicle Fitment tab to confirm compatibility.
Built from 10 mm ABS plastic, they are tough, impact and scratch resistant, and finished with a UV-protective coating. They are temperature and weather resistant for year-round use. Products arrive vacuum sealed in protective film and carry authenticity labelling. This material holds a TUV MATERIALGUTACHTEN certificate for quality.
Choose the finish that suits your build: 10 mm matte black, or 10 mm matte black with a red core highlight. No painting is required, but if you do paint, use a primer first.
Installation is straightforward with the supplied mounting kit. We recommend careful alignment and secure fastening. Re-check fixings after initial miles. Ensure nothing protrudes beyond legal limits and that ground clearance remains safe.
