I have the CA Dreaming Ram Air hood, and I am going to go with a GT500 nose. It is purely coincidental that at a quick glance (from 20 feet away and at 20 mph) my car with a GT500 nose will briefly appear like a KR....I had my hood in mind and on my car long before the KRs came out.
I am going witht he GT500 nose, because I think it is more aggressive looking and in the end, it will give my car a very unqiue look.
On your car, I agree with Gary, you car looks fabulous and very unique with the set up you have now (eleanor hood). Have to admit, if you go with KR hood with your GT500 nose, people are going to think you are tyring to clone a KR. No need to clone when your car is a trend setter to begin with.
