I know there are already a countless number of mud flap threads and people debating which are best. However, I just want to post about my experience with Gorilla Offroad Company. I ordered the mudflaps for a 2014 WRX and they were delivered within a few days, so I was pleasantly surprised with their shipping speed. I received them in the morning on a Saturday, so I decided I would install the rear set and see how they looked.
I opened the box and pulled out the flaps, and they were very rigid and thick, seemingly heavy duty. The feel was nice, but I was immediately concerned about the stiffness. They mounting hardware was alright, the screws were fine, but the rear push clips (that you screw into) were very fragile. Luckily they give you two spare, because I needed them both. One snapped when I was just trying to push it into the plastic, and a second actually was broken by the screw as I was screwing it in.
I installed them according to all of the included instructions and placed them in the highest possible mounting location. I was concerned about scraping them, so I wanted them to sit as high as possible.
I drove around with them today for about 15 miles. I went to the gym and the grocery store, so nothing crazy. I scraped them on everything! it was terrible! Any slight elevation change and I would hear the horrendous scrape.
I am terribly unhappy with them. My WRX is still at the stock ride height, so for the flaps to scrape so badly is just unacceptable. I could hardly pull into any parking lot without a horrendous scraping noise. I removed the flaps that same weekend (and never even installed the front flaps), and contacted Gorilla Offroad Company about a return and refund, because their website advertises a 100% satisfaction guarantee.
I emailed Gorilla on Sunday night, and received a response from them on Monday morning before 9am! I was very surprised about that. They offered to either refund the purchase price or to replace them with a short cut set. I opted for the refund solely because I think their flaps are too rigid for my application. They would be excellent for someone who it offloading and actually scraping isn’t an issue, but they offer loads of protection. I did find it very humorous that they referred to the scraping as their “self leveling” technology. I got a good chuckle out of that. A few days later I received a full refund, Gorilla was very pleasant to deal with throughout the entire process.
I really wanted to like these flaps. However, I think they are best suited for vehicles with more ground clearance than a stock height WRX. The price was reasonable, and the mudflap quality looks good (I wasn't much of a fan f the mounting hardware), but the actual implementation was sub-par. It’s unfortunate.
Final point: I would definitely consider trying Gorilla Offroad Company again on a vehicle such as a Crosstrek (due to it's slightly higher ride height), but the application on the WRX just doesn't work for me.
