Installed my RallyArmor flaps. Installation itself wasn't too bad. Just took a lot of time. The hardest part is making sure it's angled correctly. It's difficult to do with the wheel off and tilted by the jack. I had to put the wheels on and use a ratcheting offset screwdriver to adjust the flap angle. Easier to do with the fronts as you can turn the wheel. Pretty tight doing the rears.
