First off thanks to crfine88 for the excellent DIY! It was a great guide! My install differed a bit. I ended up bolting the factory undertray to the front bumper and installed the bumper, APR splitter, and factory undertray as one piece. Let me tell you that even without any of the adjustable rods this thing is really strong. I don't have any pictures yet of the whole thing on the car but here is a pic of the APR splitter, front bumper and factory under tray all bolted together before I took it out to put on the car.
