Quite possibly so!
I've thus far tried RallyArmour and Primitive flaps and as of this past Friday, I'm now running Gorilla flaps. These things are the real deal. They're super durable, very thick and came with all the mounting hardware you could ever need.
With the Primitive flaps I first used, I had to drill my own holes in the front flaps and cut the actual flaps because they weren't a direct fit (maybe I was sent the wrong set?). Either way, those flaps took way too long to install and were probably my second favorite as far as functionality.
The RallyArmour flaps seemed like they're more for aesthetics than actual function as they were tiny and didn't do much protecting (although they looked nicer than the Primitive flaps). This brand of mud flaps comes in last place out of the three I tried.
Then we have Gorilla mudflaps.. The mounting hardware with these flaps is by far the best of the three and took a total of one hour to install (including taking off all my wheels, etc). There are spacers for the rear flaps on the inner mounting point so they flaps actually were straight instead of curved like the other two brands. These flaps are also very thick and seem like they will be much more durable than the others. I love how they come with optional vinyls for that extra bling as well. My only complaint with the Gorilla flaps thus far is that the said vinyl was hard to apply (but I bet warmer weather would have solved this issue).
All in all, I highly recommend Gorilla mud flaps, and at $90, they're priced pretty competitively too! You can pick up a set from here
, although I would send an email to them to make sure you get the correct ones for your Foz!
