[MENTION=11705]RPI Designs[/MENTION] I think you'd have better luck once you answer this. I'm in the market and would love to pull the trigger on purchasing a 350R style spoiler (and collect $100) but not if I'm left unhappy with a spoiler that vibrates.Then please answer people who keep asking about the GT350R type spoiler. I wanted one but I read about them flopping around. I asked you guys numerous times if those reports were true, I got no answer. Neither did the others who asked the same question.
