Well for your car I would honestly say no,
But what you could do it just swap them and then generously swing the Gt copies my way (as long as they are the champagne colour)
But I must say I think you should keep the FTR's for now. They are a smaller wheel, but I think suit the shape a bit better.
(only reason I want the champagne ones is that it would go with the gold badges, exhaust tip etc on my car.)
Said it before, but that is a really nice car mate,
if for some strange reason I found my self in Vic, I would take some piccies with ya
P.S. I would say do yourself a favour and get yourself a bonnet protector.
Then colour code it by spraying it on the inside so it will not chip.)
