Weather FloorLiner & Cargo/Trunk Liner | Toyota Supra GR MKV A90

As someone who lives in Washington, I personally feel that all-weather rubber floor mats are a must. We get a lot of rain around here and aside from the water, there’s a lot of chance to drag mud inside the car.

So when I bought the GR Supra and saw that it came with the regular carpet floor mats, I knew that I would have to buy some all-weather mats. Unfortunately, Toyota doesn’t currently have an OEM option available. Last I heard from the dealership, they were told that the all-weather mats were still only in development so who knows when they’ll actually be available. This means that I had to go aftermarket.

A quick search resulted in some being available from WeatherTech. A very reputable accessory maker in the auto industry. So, I ordered the FloorLiners and here they are.

These mats are made from a patented High-Density Tri-Extruded material, which is essentially fancy rubber. This material provides rigidity while offering good traction.

In creating the floor mats, WeatherTech laser measured the interior surfaces of the vehicle to get the most accurate fitment.

When buying these floor mats, you get one for either side of the vehicle. The mats are side specific and are pretty hard to inaccurately install. The driver side has a cut out to compensate for the gas pedal.

Installation of these floor mats can be as simple as just slipping them in and calling it a day. It may seem like this is the proper way to install these mats for some because they don’t come with any instructions. It also doesn’t help that some of these mats are shipped with missing parts.

You see, these mats are supposed to come with some anchoring hooks. The hooks keep the mat in place and don’t let them move around like they would without them. If we look at the Supra’s floor liner, we see that there are two circular velcro patches. These connect to the underside of the OEM carpet mats and hold them in place. The WeatherTech mats, on the other hand, have no matching velcro patch but are supposed to come with the anchoring hooks. To install these hooks, we first have to remove the velcro patches on the floor. This is done by using something like a flat head screwdriver, lining it up with the slot in the velcro patch and giving it a quarter turn. The patch can now be removed and replaced by the WeatherTech hook. Place the hook in the space and give it a turn to lock it in place. Remember, the open end of the hook faces towards the driver. From here, it’s just a matter of sliding the mats into place and anchoring them down with the hooks.

Again, make sure that your WeatherTech mats come with these anchoring hooks. If they don’t, you can contact WeatherTech and they’ll ship some out for you.

As you can see, the mats cover a large portion of the carpet and lines the front, sides, and back of the footwell. This is nice because the raised lip helps to keep debris inside the mat.

On the main portions of the mat are channels that help to carry fluid and debris away from shoes to a lower reservoir. These channels are designed to minimize fluid movement while driving.

In my opinion, these floor mats look great in the Supra. Fitment is good for the most part and I’m sure it’s going to provide great protection for the car. But, how can we make it even better? How about adding our own custom logo? I’m sure that some people are going to want that factory look and have to have Toyota Supra branded everything. For these people, seeing the WeatherTech logo every day isn’t going to work. Especially, if it’s installed all lopsided like on mine. That’s why I made these decals. They are meant to replace the stock WeatherTech decal and slip right into the original indention. They actually fit even better than the original. Installation is as simple as peeling the old decal off and replacing it with the new custom one. With a few seconds of work, we completely transform the feel of these floor mats and make them look as if they came directly from Toyota.

So far, I’m enjoying these mats. They look great, especially with the new logos. That being said, I do have some complaints. The first complaint is with the hook anchoring system of the front floor mats. WeatherTech should’ve used the existing velcro hook and loop system. My problem with the hook anchoring system is that it introduces holes in this otherwise sealed one-piece design. This allows small amounts of water to seep through and soak the underlining and reduces the efficiency of the floor mat. Luckily, the hole is pretty small and positioned so that it gets minimum water exposure.

The second complaint is about the overall size of the mats. I think they could be longer. If we look at the driver side mat, we’ll see that towards the seat, the mat is raised to compensate for a bump in the floor liner. Well, if we actually pull the mat back to cover the bump, the front of the mat won’t rest on the dead pedal and leave a gap. So, it comes down to what you’d rather have. Protection up front or in the back. Realistically, if you use the anchoring system, you won’t have a choice as they force the mat to cover the dead pedal and, of course, the mat will leave a gap towards the rear so don’t move your feet back too far.

Along with the front mats, I also decided to pick up the cargo mat or trunk liner. This mat is made from a proprietary custom blended TPE, again, just fancy rubber. This material is advertised as being flexible under extreme temperatures. Between the cargo and the front floor mats, I don’t see a significant difference in terms of material and flexibility. They feel almost identical. In use, the cargo mat does seem to be a bit grippier. This is in part thanks to the textured finish and tread pattern that help to keep cargo in place as you drive around. If I have one complaint about the cargo mat, it would have to be fitment. When first installing it, I actually thought that I was sent the wrong mat because mine seemed overly large. It turns out that the sides arrive flat and have to be folded up to make the sidewalls. This is fine but even after I got everything in place, some corners of the mat didn’t want to stay down. They keep lifting unless I add some weight to that location. Hopefully, after the mat’s been able to sit in the trunk for a while and been exposed to some heat, it’ll hold its form better and stay in place properly.

Again, the cargo mat looks pretty good, but it can be better. Since I did it upfront, I, of course, have to match in the back. I have to replace the original WeatherTech logo with a more factory logo. Now, we have a complete product. Perfectly suited for the GR Supra.

Minor complaints aside, I would say that both mats are great. They do what they’re supposed to and provide lots of protection for the carpet liner. If you’re looking for some high-quality all-weather floor mats, definitely give these WeatherTechs a try. I’ll include links below so make sure to check them out for the most up to date pricing.
