I'm not sure you could hit 155mph with 4.09s mine is stock with 10R80 and the optional 3.55 ratio and I could not exceed 147mph with my foot to the floor on a level road with 93 octane fuel. Perhaps I wasn't in the right gear for top speed idk I was not shifting manually.
I love my Vapor Blue GT, the metallic really sparkles and shows off the blue in sunlight, it is more grey and bland looking at night or under LED light.
