Hey there folks. Got the Brabus Spoiler a few weeks ago, got it painted black like the car, and installed it today. I got to say the supplied templates have ALOT to be desired. Tape them on, then measure yourself. Use something with millimeters so your units of measurements are that much more precise. I drilled one hole, atached one mounting screw, then lined the spoiler up, and drilled the next hole, and so on and so forth, very slowly it came together. Total time to remove the top panel, bring it inside, tape it, drill it, remove tape, attach spoiler and re attach to car, then align the entire thing to fit right.... 2 hours, no help. Looks good, I'm happy.
