It's just a style, personel preference. A lot of people do it with Saxo's, Golfs etc. Guessing it's just something thats not been done to a Z and the OP wants to see what it looks like.
Some cars can pull it off, others are a no go!
That's pretty much it. . . .
Never seen one done before. .
Just bought a kit to do it, for the sake of £8 I'll give it a go and see what it looks like. . .
But it is also to serve a purpose the new strut brace I'm getting apparently touched on the bonnet so will hopefully stop it catching :-)
