Cheap but effective.
Easy to install. Stay put during high pressure wash (no direct blast). Work well. Aesthtecially adequate.

These are perfect!
Great product and a great fit. So far, they are doing exactly what they're designed for. Keeps extra rocks and debris from accumulating on the way to cruise-ins & shows. No one even notices them when they're in place! Thanks for a very useful part of our car show war chest!

Keeps the rocks out
As advertised it keeps the rocks out of the gap behind the front tires. Fit was snug, as it should be. No issues.

Works as advertised but should be thicker for the price paid
Fits like a glove but they should be longer as to cover the entire rocker behind front tire. They are 1” thick. They should be 4 or 5” thick.

I was a little skeptical....
I had my doubts about these, but I quickly grew tired of rocks on the side skirts so I ordered a set. They go on extremely easy, which made me wonder if they were gonna fly off at highway speeds. I've since had the car up to 120 mph and they haven't moved a bit. Plus no more rocks on my side skirts. A must have for any GT350!!!!!

Works perfectly.
Great product! Stops the rocks and gravel from being thrown down the side of the GT350. Perfect shape and install time was about 30 seconds.
