I recently installed the HFP front lip on my sedan. I followed the instructions word for word, and everything came out looking good. However, I noticed when on the freeway, I hear a rattling sound coming from the front. Obviously I cant point out the exact area that it is coming from, as this only happens at 70+ mph. The one thing I did not use in the supplied hardware was the optional spacers, I felt no need for them. I know without being in the car its hard to say, but does anyone have ideas and or suggestions? Any would be greatly appreciated.
