I have a set of tinted tails for the CS, but I didn't like them very much. I live 3 miles down a dirt road and the Cutty is lowered and it will scrape over a few of the ruts. I don't have plans to drop the GTP yet.
I don't think I will register the CS this year and it probably won't even get driven. Though I may take it in the back 40, and cruise around once or twice on the trails.
