@ZInferno: Congrats to your KW! But your front is too low imho. Driving fast press the car down additionally (aerodynamics). Driving over small a small wrinkle or something will let your car hit the ground...or the fender, as you already mentioned.
Keep in mind that the car will settle after a certain period of time to max 5-6 mm front/rear. My car setttled about 5 mm front/rear. I don't have an actual photo to compare with the one taken on the Leipzig fair (suspension was built in 2 days before photo was taken). There's less room now between fender/tire.
