Ok, they're on! It was a bit more trouble than I thought, took me about 2 hours on a cool sunny day in my driveway. I don't have much experience with mud flaps or messing with fender liners though. But I like the results. Some tips:
-There are a bunch of screws, but only two longer screws.
-Don't try to go by their photocopied directions. Either print out the instructions PDF from rallyarmor.com on a color printer or take a laptop outside with the PDF up . I really couldn't grasp what the directions were saying in some parts without seeing the pictures. In their pictures the car is red so you can more easily see what's going on.
-On the front flaps, you won't be using the top hole for the mud flaps. You will put the top screw back in when you're done, but all the screws need to come out so the fender liner can be pulled out of the way during part of the installation.
-You'll need to remove the rear wheels or at least jack up that corner of the car. I jacked mine up, even so it was tight. Good opportunity to try out your jack before you're on the side of the road with a flat.
-I'd never drilled out a rivet before, but just get a bit a little bigger than the little hole in the center of the rivet, stick it in the hole, and take it slow. The rivet will come out once you've drilled deep enough.
-With the wheel on, the screws on the rear flaps are hard to get to/tighten. Remember the rear bumper cover will flex outwards (to a point.). A stubby or long-shafted screwdriver helps. The middle screw on the back flaps I still had to use pliers to tighten though.
Now for the pics. I wanted clearer pics from the rear, but it was getting late and then sun was behind the forest across the road, so it was getting dark in the driveway:
A rear flap. The logo is etched into the flap, you can't hardly notice it except when the light is right:
The hardware. Remember two screws are longer. In the top left are the original screws from the MS3 fender liner/side skirt.
Overall these are quality flaps, they are packed carefully with paper in between each flap, so they come to you undamaged. The hardware is good, only place they could use improvement is they need to invest in a color printer for the instructions.
I'm looking forward to having much less crap on the sides of my car.
