well i think your cars wicked steve with the mods you have done on it
i think you should save up and get a big spoiler+boot as a spare then you can give it a change now and then.
as for telling if a spoiler is real or a copy. look at the brake lite,at each end the real ones have wot looks like a bullet tip on the end of the brake lite. copys dont. i not 100%
i wish i had a turbo
