Looks good but I think it would look weird if you put it where the Nissan hamburger emblem is. I can picture it on the passenger side dashboard like how Ferrari has the "458 italia" badge. I guess i'll have to wait and see when it's on the car.
I've never been a fan of dash lettering though. I would maybe do like a R35 logo really small maybe on the dash all the way over by the passenger side vent designating which model of GTR. I was going to just center the GTR logo but I have seen a guy do that and it looks good but a little empty and I also still want o represent NISSAN because I love nissan cars. (Had a nissan hardbody pickup, armada, maxima,GTR...)
I centered it perfectly the fist time but it looked a little odd for some reason. I'll rock it this way for a bit but may move it down just a tad. When I was a designer I always would raise things just off center to kinda create movement in space or just for a different feel or transition from one space to another.
