Review on Sparco 03791RS High-Performance Red Universal Mud Flap: Optimize Your Search! by Mark Saric

I know I need to trim the fenders but it would be nice to know which side faces the tires (smooth side if textured). I think the material will hold up. However the flaps are very flexible and I use them in my caravan so I hope they offer protection when I'm out on the road. Time will tell if the fenders work properly so I'll watch how well they hang and if they curl and most importantly to see how much dirt is on the trailer.
