You've just saved me some cash, because I was thinking about getting mine colour coded and I don't like the idea now I've seen yours...sorry!
Also, I've just put 1.2 rear lights on mine as I thought it looked too grey at the back, and I think they work better. Hey, if we we had the same opinion everything would be the same. The rear lamps are definately sealed.
Oh and the spoiler? Sorry mate, but they've got the wrong spoiler in! Check the pic of mine below and you'll see its different. Maybe they put the wrong part number on the bag? I work in car parts, it happens a lot.
