2015-2021 Subaru WRX/STI Floorliner Set by COBB x WeatherTech

FloorLiners are laser measured to protect the front, back and even up the sides of your vehicles footwell. For ultimate strength and dependability, FloorLiners feature high-density core materials and are engineered with advanced surfacing that carries messes away from shoes and clothing. WeatherTech products provide complete automotive interior carpet protection from mud, dirt, snow and more.

The WeatherTech FloorLiner lines the interior carpet up the front, back and even up the sides of the vehicle's footwell. Digital laser measurements of interior surfaces offer a consistently perfect fit!

A patent pending High-Density Tri-Extruded (HDTE) material allows for a rigid core for strength while offering surface friction to the carpet, as well as tactile feel to the surface! Advanced surfacing creates channels that carry fluids and debris to a lower reservoir with further channeling to help minimize fluid movement while driving! Once fluids become trapped in the reservoir, away from shoes and clothing, they are easily removed from the WeatherTech FloorLiner over the door sill. No muss-no fuss!

The rear FloorLiner incorporates many of the same design features as the front FloorLiner and (where offered) is manufactured from a proprietary custom blended TPO (thermopolyolefin) that is not only wear resistant, but also remains flexible under extreme temperatures. The Rear FloorLiner is either one piece or two piece depending on the vehicle application.

FloorLiners help protect resale value too! Simply put, the cost of owning a vehicle is the difference between what you pay for it and what you sell it for. There are many factors that influence resale value; miles, exterior condition, maintenance history and of course interior condition. The FloorLiner is proudly designed, engineered and manufactured with American made tooling in the USA.

Very nice

Love these, the cobb logo sets them off! They are built well and they work very good to help keep all the dirt and whatnot from being drove into your carpet and easy to clean

Garrett Maclean

These fit perfect, top notch figment and protected all the right areas

Daniel Dacosta

Makes the car look so much cleaner and you gotta love the cobb badge 👌


They work and looks great and fit as expected just a little upset my Cobb logo was off center had to peel it off and replace where it should’ve been. Great product I guess the people putting the logos on just don’t care

Weather Tech Floor Mats

Good, rugged mats to protect the interior, the whiteCOBB logo looks great against the dark color of the interior floor and adds a pop of color. Easy to clean and easy to fit. Suggest letting them warm up a bit before install for better playability
