Maybe he is right - can only go one my experience, to me it is fine but I am sure a purest might have issues - I could probably do some more tweeking on alignment to get it perfect (and yep, painter mate sanded/prepped etc). Only issue I have is that at speed it can move a little (worried that it might fly off, but I am thinking this is more to do with the scoop providing lift and it hasn't budged yet). Thinking about bonnet pins, but also thinking that might look a bit too "try hard"
I did see the bolt on scoops, not really for me and I wanted the grill slots
I am sure there are some in the S550 group in Sydney, best check out a few
cheers
