Plain fender. It fits my SUV and makes a definite difference to the car, no more squishy streaks on the front doors or rear bumper, and at high speeds in the rain the cloud of fog behind the map is much smaller. The installation depends on your car, in my case I cut the front fenders a lot but the rear ones were installed as is, I used a combination of the original screw positions, plastic clips and some brackets. , Splashguard can be trimmed with heavy duty or kitchen scissors. For what I paid these are amazing fenders.
