I had the stage 1 spoiler installed today and I have to say, I'm very pleased! It adds a very nice touch to the rear of your GP and helps you stand out in the crowd. I even took it a little further and went with a two tone paint scheme! go here to see pics: http://www.cardomain.com/ride/2158579 I'm not a real big fan of the inferno spoiler...this was a great (lower cost) alternative! I promise you won't be disappointed.
