These thick rubber mats from Subaru are perfect for inclement weather, or any location where you'll be tracking water, snow, mud, or sand into your WRX. The deep corrugated rubber captures tons of materials, and cleaning the mats is easy -- just hose them off and shake them dry. (Picture above shows them after a recent rainstorm. They work!)
Safety tip: Only use ONE set of floor mats at a time. Swap these in for foul weather, then put the cloth mats back in come summer time.
Set of four mats fit 2002-07 Impreza and WRX, including STi (as shown above). Charcoal in color.
